I don't know where Gem comes from, but I'm trying to install Jekyll from GitHub, and it says for start ups you need to install Gem. How do I install it?
I've looked up already on Google and on StackOverflow. The results didn't help at all. Thanks!
You need to have Ruby installed in order to use Gem. Depending on which OS you're using depends on the installation for Ruby but here is a link for windows.

Hi I'm a little stuck with with this. Never had this issue in the past. I get this error below in capistrano log details. I tried to update mimemagic and followed this here https://www.rubydoc.info/github/mimemagicrb/mimemagic
The error
Your bundle is locked to mimemagic (0.3.5), but that version could not be found in any of the sources listed in your Gemfile. If you haven't changed sources, that means the author of mimemagic (0.3.5) has removed it. You'll need to update your bundle to a version other than mimemagic (0.3.5) that hasn't been removed in order to install.
I appreciate your help with this.
So this is due to mimemagic being yanked due to copyright issues. Anyways, I'm on a mac and I'm using rails 6, I'm not sure what you'd do if you're using older versions of rails. My issue got solved by doing the following:
First please make sure you have work committed to git prior to doing anything.
In gem file
gem 'mimemagic', '>= 0.3.8'
Then in your terminal run
brew install shared-mime-info
or you may have to run
brew upgrade shared-mime-info
Finally run
bundle update marcel mimemagic
So that solved the issues for me. Here is a good reference.

Also you may want to follow up on any copyright infringements.
How to install rvm(ruby) on RHL7 using centos repo.
I know if we are using centos repository we should be using centos OS and not RedHat, but we have a proprietary software that require Redhat.
when I try to install ruby 1.93 using rvm I got this:
rvm install 1.9.3
Searching for binary rubies, this might take some time.
No binary rubies available for: redhat/6/x86_64/ruby-1.9.3-p551.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Checking requirements for redhat.
Unable to locate SystemId file. Is this system registered?
Our client does not have registered system with redhat, So I did configure centos repository.
But how can I tell RVM to use this centos repository?
I managed the problem running:
rvm autolibs read-only
In that way rvm do not try to download the dependencies from redhat. But it tell us what is missing, so we can install what is missing manually with yum install from centos repository.
RedHat uses the concept of software collection to offer update packages for Ruby, Python, etc:
softwarecollections
For your case, they have software collection for Ruby193 and Ruby22.
On each page you will find instructions on how to use it.
when I typed in $ ruby -v the output appeared as below:
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin11.4.0]
In the past, I used to see the output as:
ruby 1.9.3
Why is my ruby version appearing with more data now? I am new to programming and am wondering if I messed up my computer. Help! Thank you in advance!
Are you using RVM to manage your ruby versions? If not I would reccomend doing so.
https://rvm.io/
Chances are, you upgraded your Ruby installation somewhere along the line (or your system package manager did). It's very unlikely that you messed anything up.
It sounds like you are not using RVM, and that the system package manager installed an update. I would strongly recommend using RVM, it will save you tons of head ache in the future.
https://rvm.io/rvm/install/
If you are not familiar with it, it is a great version manager created by Wayne Seguin. It allows you use specific versions of ruby and specific gems for different projects.
I sucessfully installed Ruby, version 1.8.7 and have been trying to install Jekyll in the Terminal using sudo gem install jekyll. Here's the error I get:

I've read a bunch of topics, but can't get anything to work. Many topics say I have to have XCode first, but it won't even download, much less install. I read that in Lion you have to set up another administrator and install it under that profile, so I did that, but the install package doesn't exist. It won't even download. I think this may be because I'm not a registered Apple Developer?
Another recommendation was that I install Ruby RVM - this also won't install. Here's the command I used: bash < <( curl https://rvm.beginrescueend.com/releases/rvm-install-head )
And here's the error I get:

I only care about Ruby RVM and XCode to the extent that I need them to install Jekyll. I'm just trying to get my Github blog going and I can't seem to do it. I've read and read and read documentation and there's something I'm missing. I'm pretty sure it's knowledge everyone's assuming I have - I don't. I'm a beginner programmer. Any help would be much appreciated.
Ok, here's how I got it to work. It was kind of a random experimentation process until something worked.
I installed XCode and Ruby RVM per others' suggestions and the latter led to my resolution. One of the suggestions on this page said to run "rvm requirements" and read the text. It basically tells you what you need to run & upgrade rubies. This documentation was quite helpful. It explained that what I needed to install Jekyll wasn't really XCode - it was GCC. Evidently, older versions of XCode came with GCC, but newer versions do not, which is why installing XCode didn't solve my problem. It also directed me to where I could download & install GCC, warning me that installing GCC over a newer version of XCode is known to cause problems. So, I uninstalled XCode & headed over here to install GCC.
It was that simple - I installed GCC and Jekyll installed in seconds.
ERROR: Error installing jekyll: ERROR: Failed to build gem native extension.
So the error is "Failed to build gem native extension." when you run sudo gem install jekyll command. You'll find a tip in Jekyll Wiki's Install section:
If you encounter errors like Failed to build gem native extension on Windows you may ...
On OSX, you may need to update RubyGems:
$ sudo gem update --system
So, try to update your RubyGems and run sudo gem install jekyll after that. And I think you don't need to install ruby rvm if you're not a ruby developer.
Btw, I think Ruby v1.9.1 is a recommended version.
And for your Xcode related question, you can download it from App Store though you're not a registered Apple developer. It's free.
Xcode is useful when you need to build some libs with gcc (gcc will be installed together after you've installed the Xcode). But I've no idea whether you'll need it when you install the jekyll.
I tried all the solutions above and did not work. I posted my answer here originally:
RVM requirements error
but for brevity, this is what I posted:
It seems that on OSX 10.9 and XCode5 moved some libs around on us. So I had to install XCode5-DP6 (Dev Preview 6), opened up DP6 and in the settings, you have to tell the command line tools to use the new DP6 build and not the Standard XCode from the marketplace.
First, I had to install homebrew. Nothing liked to play with macports. I am on my first mac as of only a month ago, so macports was just what solved apache for me at the time. I then had to run 'brew install autoconf'
Once I did that I then ran rvm requirements, everything installed without issue. then sudo gem install jekyll from there and it all works like a charm now.
I'm sure once Mavericks is actually released this will get ironed out. We are using early releases after all...
Same issue encountered! After reading this article and random experimentation like following,
xcode install
curl -sSL https://get.rvm.io | bash
sudo gem install jekyll
fixed the issue and could successfully install jekyll
I have virtualenv set up and working correctly on my mac os (leopard) running python 2.6 & django 1.2.3. I want to install Satchmo but I haven't found solid instructions for a mac install using virtualenv. Can anyone help regarding this? thanks.
If you're using buildout with virtualenv then try this: https://github.com/shywolf9982/satchmo-buildout
Of course installing newest XCode ie. 3.1 or 3.2 is a must..
Unfortunatelly compiniling stuff on Mac can give you the creeps... My collegue and I, were fighting 12h with installation of geodjango on Spatialite database, and we didn't make it after all :)
If you're not using buildout then just use macports for installing modules listed in above repo's buildout.cfg file.
Good luck!
This Satchmo Project post contains the instructions I follow on Snow Leopard. I use Homebrew and/or MacPorts in lieu of the Debian package tools.
