While trying to troubleshoot another issue with my project, I must've broken something along the way, but I have no idea how to fix this.
These are my import statements for the project:
pragma solidity >=0.6.6;
import "#openzeppelin/contracts/token/ERC721/ERC721.sol";
import "#chainlink/contracts/src/v0.6/VRFConsumerBase.sol";
And this is my brownie-config.yaml
depencencies:
- OpenZeppelin/openzeppelin-contracts#3.4.0
- smartcontractkit/chainlink-brownie-contracts#1.0.2
compiler:
solc:
remappings:
- '#openzeppelin=OpenZeppelin/openzeppelin-contracts#3.4.0'
- '#chainlink=smartcontractkit/chainlink-brownie-contracts#1.0.2'
But despite all this working until yesterday, trying to compile only gives me these errors:
PS C:\Users\XXX\Desktop\Project> brownie compile
INFO: Could not find files for the given pattern(s).
Brownie v1.16.4 - Python development framework for Ethereum

How do I solve this?
I've seen some answers to similar issues referencing node.js or local copies of the stuff I'm trying to import, but isn't this command supposed to pull stuff off github?
Why is it failing to do so out of nowhere?
Install Openzeppelin at the root of your folder by using npm
npm i #openzeppelin/contracts
same thing for Chainlink
This is because the solidity extension is looking in the wrong directory.
Below step fixed the issue for me -
Change the settings in Solidity extension in VSCode.
The default settings include: "solidity.packageDefaultDependenciesContractsDirectory": "contracts" Users need to change the setting from contracts to an empty string. "solidity.packageDefaultDependenciesContractsDirectory": ""

I've imported the Open Zeppelin ERC721 token standard into my VS Code with the Solidity extension, but see the following warnings on all my OZ import statements:
Screenshot of error
Why is this happening and what is the workaround for this warning?
What I've tried:
change default workspace compiler to localNodeModule (began to throw other warnings like on the pragma solidity line)
Example of solution I've tried
Just install the Solidity+Hardhat Extension ,this will take care of the errror.
run below command
npm install #openzeppelin/contracts
Change the import line like this
import "./node_modules/#openzeppelin/contracts/token/ERC721/ERC721.sol";
You could try this solution here, the only one that helped me.

When you compile programmatically using solc, new syntax was introduced, which you have to include in compile.js.
// New syntax (supported from 0.5.12, mandatory from 0.6.0)
var output = JSON.parse(
solc.compile(JSON.stringify(input), { import: findImports })
);
You should have a helper function for finding imports
function findImports(relativePath) {
//my imported sources are stored under the node_modules folder!
const absolutePath = path.resolve(__dirname, 'node_modules', relativePath);
const source = fs.readFileSync(absolutePath, 'utf8');
return { contents: source };
}
Unfortunately I ran into this error too & just gave the path manually:
import "/home/ev1lclow3n/node_modules/#openzeppelin/contracts/token/ERC721/ERC721.sol";
This solved my error.
(I'm a linux user so path may differ for you)
Thanks ;-)
you have to manually guide the open zepplin import to its source file if you have it downloaded in your node modules then all you have to do is to change its path like this " ../node_modules/" and also make sure to use the latest extension of juan blanco's solidity extension and solidity and hardhat extension and if you are following a tutorial your first lines of codes would probably be import "hardhat/console.sol"; all you have to do here is to manually direct only this file to its designated place and the others would do it by themselves.
What you have to do is:
If you have "Solidity by Juan Blanco" for Truffle and "Solidity by Nomic Foundation" for Hardhdat, and if you are using Hardhat, disable the one by Juan Blanco and just use the one by Nomic Foundation, it just worked for me.
Screenshot
Make sure to create a Hardhat project (npx hardhat) and install:
npm install --save-dev "hardhat#^2.12.7" "#nomicfoundation/hardhat-toolbox#^2.0.0"
npm i #openzeppelin/contracts
Ok. That was a dumb question. Two things you have to do:
(1) Install the OZ library via
npm install #openzeppelin/contracts
(2) If you see Error HH606 (i.e. project can't compile), it's likely because The Solidity version pragma statement in these files doesn't match any of the configured compilers in your config.. Ensure that your pragma version matches the version in your hardhat config.
Hope this helps.
I am having trouble installing a module I created in Julia. I am running the Julia plugin under Visual Studio Code. If I run the file below with Ctrl+F5 I get a message
ERROR: LoadError: ArgumentError: Package Utils not found in current path:
- Run `import Pkg; Pkg.add("Utils")` to install the Utils package.
This is the file:
module demo
using Utils
greet() = print("Hello World!")
end # module
If I follow the advice on the error message I get another error message:
ERROR: LoadError: The following package names could not be resolved:
* Utils (not found in project, manifest or registry)
I also tried inserting this line:
import Pkg; Pkg.add(path="C:/Dropbox/Code/Julia/demo/src/Utils.jl")
and got this message (although the path definitely exists):
ERROR: LoadError: Path `C:/Dropbox/Code/Julia/demo/src/Utils.jl` does not exist.
The files demo.jl and Utils.jl are in C:\Dropbox\Code\Julia\demo\src\ and the demo project has been activated as can be seen in the REPL. The OS is Windows 10 Pro.
Any help will be greatly appreciated. Lots of time wasted trying to make this work.
Module and packages are not the same things. In short, packages are modules plus a set of metadata that make it easy for the package to be found and interact well with other packages. See here for a tutorial to write Julia packages:
https://syl1.gitbook.io/julia-language-a-concise-tutorial/language-core/11-developing-julia-packages
In your case, if you want to load a local module, just type include("fileWhereThereIsTheModule.jl") followed by a using Main.MyModule or using .MyModule. Note the dot... without it, Julia would indeed look for a package and to let it find your Demo or Util module you would have to either change an environmental variable or place your module file in certain predefined folders. Using include followed by the "absolute or relative position" of the module you don't have to do either.
I have stumbled upon a problem in importing the package in Flutter, I tried to solve this by running flutter packages get and also shutting down the project in Android studio and reopening it.
import 'package:task_02_category_widget/category.dart';
Here is the line above, and the error I'm running into when I run it gives the following error in the console.
Your application could not be compiled, because its dependencies could
not be established.
The following Dart file:
/Users/username/Documents/flutter_rectangle_2/lib/main.dart
...refers, in an import, to the following library:
package:task_02_category_widget/category.dart
That library is in a package that is not known. Maybe you forgot to
mention it in your pubspec.yaml file?
If task_02_category_widget/category.dart is part of an old project you are reusing you should put it in a folder in your flutter application and include it like "../ folder /task_02_category_widget/category.dart ". If it is part of github repository you have copy pasted from, just copy the file and use the step above. Most probably you are looking for that . In any other case check here to find the source code.
You should have in your project at a file called pubspec.yaml a definition like this:
name: my_app
dependencies:
task_02_category_widget:
Let’s say that your package is laid out as follows:
task_02_category_widget/
lib/
category.dart
Then, you can import it:
import 'package:task_02_category_widget/category.dart';

What's weird is that im using the same linting configuration with another project, and i had no issues at all.
I'm using:
babel-eslint#7.1.1
eslint#4.0.0-beta.0
Any ideas ?
Even though I had same package.json, babel-eslint was set as "7.1.1" in one and "^7.1.1" in the other.
Basically ESLint v4 uses a new fork of escope, which was then updated on version 7.2.3 of babel-eslint.
So, adding the little ^ to my configuration fixed my problem.
Maybe I am making a fundamental error, but I assume you have to install the Import / Export plugin on IP3.9 to make the zip file before you import it to the new ip4.1 site ?
The plugin will not install in IP3.9 there is an error "plugin.ini doesn't exist"
The Import / Export plugin is not in the IP3.x format
ip_plugins/group_name/plugin_name/files
so I do not see how it can be installed.
If I try exporting data from IP4.1 I get the following error message
Error:
Fatal error: Call to undefined method Ip\Page::getType() in /var/www/ip41/Plugin/ImportExport/ManagerExport.php on line 207
I am probably doing something stupid, but I cannot see what
Alan
For v3.x version you must download a 3.x branch of the plugin - https://github.com/impresspages-plugins/ImportExport/tree/3.x
For the error in v4.1 open an issue on GitHub - https://github.com/impresspages-plugins/ImportExport/issues
I hope it does make sense now.
