I am trying to use LibGit2Sharp in Unity 2018.2 beta, because previous versions of Unity doesn't support .NET Framework 4.7.1, which will be needed for LibGit2Sharp.
I wanted to try a few things first and came across the following problems:
if I try to clone a repository (I have used the example on GitHub first: https://github.com/libgit2/libgit2sharp/wiki/git-clone), I get an "LibGit2SharpException: failed to send request" error in Unity.
I have also tried to get information from a working copy. I create a Repository with new Repository(string path), get the RepositoryStatus from it with rep.RetrieveStatus(new StatusOptions()). Now, if I try to access the state of files, it causes a crash in Unity. No matter if I iterate through all files and want to print file.State, or want to get a specific FileStatus list from the whole status (example: status.Added). However, printing the filepaths works.
Fetching does not works either for me, it throws the same exception as the clone command.
I think the second one is maybe just an issue, but clone and fetch should work.
Update: sadly, I keep facing problems in my project with libgit2sharp in Unity. I want to make a commit, now if i try to iterate through the StatusEntries to stage the files, Unity just crashes, but sometimes it works. It is really hard to reproduce the bug, and often I get different crashlog-entries for the same process. The last time I have tried today the error was:
0x00007FFB417386CE (git2-6311e88) [c:\projects\libgit2sharp-nativebinaries\libgit2\src\diff_generate.c:1352] git_diff_tree_to_index
I have created a test-repository in my program using the Github API and cloned this to my pc, this works fine so far. And then if I create some files in the folder and want to make a commit, I run into the error above. Sadly this is one of several other issues and I can't really make progress with my project.
I have installed libgit2sharp and binaries with the Nuget Package Manager of Visual Studio.
Does anyone have experience with LibGit2Sharp and maybe some ideas of what I could be doing wrong, or why these things don't work for me?
Update 2: I'm still trying to solve the problem. I have now tested multiple times the different ways to get informations about the file-status of a repository. The best way to do it in my project would be with Repository.RetrieveStatus(filePath), now if I try this, it throws an AmbiguousSpecificationException. Can somebody explain, what does this exactly mean and how can I avoid it? I have also tried to force a literal path evaluation with Repository.RetrieveStatus(new StatusOptions() { DisablePathSpecMatch = true }); as recommended in the message of the AmbiguousSpecificationException, but then Unity crashes with the error-log in the first Update of this Post.
I had the same problem where Unity crashed on RetrieveStatus(); call. Seems like this might be a bug in LibGit2Sharp since RetrieveStatus("filepath") worked for me. I used the latest libgit2sharp commit (0dcaefc) and Unity 2018.3.0f2.
I used the absolute filepath and "\" instead of "/" (running on Windows 10).

I'm facing this No such module 'SomeModule' error in an XCode solution that I've inherited from some other developers. Initially the error is No such module 'ObjectMapper', but I find that if I swap the position of that line with the one below, it becomes No such module 'Alamofire'.
I've tried all the simple things suggested on this site (and others), making sure I'm opening the .xcworkspace file, deleting everything and re-installing (derived data, the whole Pods directory, etc.), updating cocoapods, etc.
I suspect that what's actually going on is that either the pods themselves aren't building, but for some reason the errors there are making their way to XCode's obtuse errors list, or that they are building but somehow not being linked correctly.
This is actually a project I've inherited from some other developers, so it's hard to know what weird or wonderful configuration they've done to break things. They are using an approach that I've not seen before where there's 3 build schemes for different environments (in this case Develop, Stage and Prod) then this kind of parent scheme for all the other three.
I've also tried going to 'Manage Schemes' then ticking the 'Show' checkbox for the Pods-Sunflower project. When I try to build just that project, I get a bunch of errors (mainly for Facebook, Google and Realm pods) that say things like:
Unable to load contents of file list: '/Target Support Files/FBSDKCoreKit/FBSDKCoreKit-xcframeworks-input-files.xcfilelist'
I don't expect anyone will be able to provide me a set of steps on how to solve this issue (I mean, that would be great), but I am hoping that someone can help me find ways to just work out what the problem is here, like:
How can I verify that all the separate pods are actually building?
Is there some folder where I can see all the built pods?
When you get a No such module 'SomeModule' error, where is Xcode trying to find the modules (like, in the file system? where?)
Thanks. I know this is one of those perennial issues, appreciate any advice.
The solution which worked for me was:
First thing i do when i got project from another developer is make a copy of pods and completely delete following files
Podfile
Pods folder
Podfile.lock
xcworkspace
In case you already once use that same project try deleting derived data
After deleting pods, reinstall pods and open project and let xcode do indexing of your project and after indexing look left side where warnings and errors shows, In there sometime you just have to just click and update or convert whatever xcode suggesting.
Note: - Sometimes doing same thing doesn't work try changing sequence because its xcode sometimes become dumb. Also try restarting
Honestly in these situation all i do is hit and try.
But above steps generallt works for me.
I am having an issue in Unity where every time I launch the editor it asks me to enter in safe mode because there are a lot of errors and when I press ignore it launches and I can see in the console a lot of errors with the UI and I found out that I cant create UI elements directly in the hierarchy. I tried to update from 2020.3.13f1 to 2020.3.14f1 and for the first launch everything was fine, with no errors, and I could create UI elements but then when I restarted to make sure everything was actually fine, all the errors popped up again and I cant create UI. Why does this happen and does anyone have a fix because I can't find it anywhere online.
Try not to enter Safe Mode. Enter the editable project. There go to Assets-Reimport All.
It did it to me too, it's probably a Unity bug, this method fixes it. Practically it reimports the whole project by itself, avoiding that the bug gives you problems (such as those like UnityEngine.UI does not exist or Monobehavior does not exist, etc.)
Obviously you will not lose any assets and everything will be fine as before receiving the errors.
Have this issue with any template 2020+ versions
Always shows 2 empty errors on console at first run ,even on an empty project
Will try to install 2019 and hopefully work again
in my case some side app ran caused some error in the installation of Unity.
Nothing amid aboves helped.
Thus I decided to fully reinstall it from scratch to default one.
Now it worksok. But before that . To wipe out the Unity thorowly you need in:
uninstalling Unity and UnityHub in windows' settings
remove all related/remained folders in "C:\Program Files"
remove related/remained folders in "C:\Users\myname\AppData\Local "
in Register Editor go to clean unity like folders in "Computer\HKEY_CURRENT_USER\SOFTWARE"
optionally, remove sample projects in "C:\Users\myname"
You're very likely simply opening the wrong folder, it's a common mistake
Or, you have possibly moved around the folders that you cannot move
Also - it's a nuisance but it's best to install the "hub"
Im getting this weird error that I have never seen before and i have like 400 of them and they i think are all different. Here is an example Library\PackageCache\com.unity.test-framework#1.1.20\UnityEngine.TestRunner\NUnitExtensions\Runner\UnityTestExecutionContext.cs(125,34). This also happened right after my pc shorted out. I fixed it loaded up unity and all my files were gone. I was planning on trying to redo some of my stuff when this came up. I'm also having a warning about a meta data file existing but its packages cant be found. I don't know if these are connected or not. This is also a brand new project so its not anything old.
Answer: Go to your library and you will find all your projects and such there. If you locate to the project you are currently working on find a folder called package cache. Delete this and you will have no more errors!
I try to get the machine learning project of Unity running. The project can be found here: https://github.com/Unity-Technologies/ml-agents
Following all the necessary steps to set everything up, everything works fine until I try to use a pre-trained model in an internal brain, e.g in the 3D-Ball example. On pressing play in the editor, it says to have stopped working and the editor crashes. Same goes for a successfully compiled executable.
Since I can't find any crash logs, I absolutely don't know what's the cause to this. Anybody had the same issue and solved it, or any ideas on this?
I'll just add the steps I made to set my project up, in case somebody wants to reproduce or check for mistakes I made:
Download zipped project from github
Open project with Unity 2018.1.1f1
Add ENABLE_TENSORFLOW to predefined symbols
Download and install TensorflowSharp Plugin
In the 3DBall Scene select the brain and switch BrainType to Internal
Run in editor or compile and run, results both times in a crash
EDIT
What's making me wonder is that I got it working just fine training an external brain in python using a compiled executable. So my thoughts were it should be much more easy to just forward pass a trained net, if it's working doing forward pass and back propagation. But it says though that external brain still is experimental, so not sure if that just will not work until some future patches.
EDIT 2
So I tried using an internal brain in an older version of the githubs project, which then worked quite fine. Also I used an older version of the TensforflowSharp Plugin. I'll try to figure out, which version still works and gonna post my results here ;)
To conclude, the problem was actually the recent version of the TensorflowSharp Plugin. Using an older version, which I found somewhere worked fine. I don't have the link to that version anymore, but in case someone experiences the exact same problem, I could search for it or upload it somewhere.
I accidentally published Composite C1 from Visual Studio with "Precompile during publishing" when I first set it up and have now come to realize that several plugins do not work with precompile turned on. Unfortunately I have no idea how to reverse this. I've tried several things to no avail. I usually end up with a 500.0 error. If I go to the admin interface everything is working properly, and I can even preview the pages, but from the customer side all I get is a 500.0 error.
Of course I could republish from the Visual Studio project I have, but that project has the default template on it. I've tried copying what appears to be changed on the server to the original project but I end up with a 500 error. I've tried removing all the precompiled stuff on the server but I end up with a 500 error. I'm pretty lost.
At this point I'm willing to do anything. Is there a doc explaining how to copy the content to a newly downloaded copy, kind of like an upgrade doc but "side-grading"? I am using the most current version at the time of writing this 4.2 Update 1
Thank you
Solved use the PackageCreator suggested by wysocki's answer. It was not exactly straight forward to create the package. The errors can very cryptic at times. So here are some of the issues I encountered and how I got past them:
wysocki was correct to suggesting starting with a bare bones installation even though my original project was started with the Venus theme. I tried both ways.
I encountered issues with the MasterLayout and the Page Template Features which are currently not supported by the PackageCreator, although they may be supported in future versions. The solution was to add the missing elements to the fresh C1 project from the original C1 installation in the App_Data/PageTemplates and App_Data/PageTemplateFeatures folders.
A few times I ran into an issue where I added the same page or function twice to the PackageCreator. This was obviously my fault, but it should be mentioned that you can add the same site element twice which throws and error on import. Make sure you are careful to only getting one of each when creating the package to be exported.
If you are getting and error and it uses and Id like "4061397b-ee9e-4512-984d-f2b2d41eb654" I've found that it was very helpful to extract the zip file you are trying to import and then search the extracted folders for that Id. The lines with the Id usually have more information on them that will help you to identify exactly what content page or whatever the error is being generated from.
If you are using installed packages in your project like SimpleSearch for example, make sure you don't add it's functions to the PackageCreator. Install them separately.
I had an issue where I somehow had an element in the Data section that didn't have a "type". The error simply "The type cannot be empty". This was obviously tough to find so I suppose the lesson is, less is more. If you think your project might have a few elements that are unnecessary, don't add them at first and see if the project you import them into complains about missing them. It's much easier to troubleshoot missing elements than it is to figure out which element is causing the issue that you really didn't need.
Is there a doc explaining how to copy the content to a newly downloaded copy
You can try and export content / templates / anything else related to a "package" via Composite.Tools.PackageCreator.
Its latest version gives you quite a lot of flexibility in what you can export ("package") - please its user manual.
Once the package is made and downloaded, you can go on and install it on a new website. If you export / import a lot of content / templates etc, it makes sense to have a "Bare Bones" site as the new one.
All the starter sites like "Neptune", "Venus" are installed as a bunch of packages in specific order during Composite C1's initial setup.
