Hey everyone! I’m trying to figure out how to get a gem installed straight from its GitHub repository instead of the usual gem sources. I know it’s possible, but I’m not sure about the exact steps. Does anyone have experience with this?
I’m particularly interested in grabbing the most recent version from the main branch. Is there a special command or something I need to add to my Gemfile? Any tips or tricks would be super helpful!
Also, are there any potential pitfalls I should watch out for when installing gems this way? Thanks in advance for any advice you can share!
yo, i’ve done this b4. u can also use the :github shortcut in ur Gemfile:
gem ‘coolgem’, github: ‘user/repo’
its faster to type. just remember, github gems can be unstable sometimes. test well b4 going live!
I’ve dealt with this situation quite a few times in my projects. While the other answers cover the basics, there’s a bit more to consider. When installing from GitHub, you’re essentially working with potentially unstable code. I once spent hours debugging an issue caused by a gem I pulled directly from GitHub.
One thing I always do now is check the repo’s issues and pull requests first. This gives you an idea of any ongoing problems or upcoming changes. Also, if you’re working on a team or planning to deploy, make sure everyone’s aware you’re using a non-standard gem source.
Another tip: you can specify a ref (commit hash) in your Gemfile for extra stability. It looks like this:
gem ‘gem_name’, git: ‘https://github.com/user/repo’, ref: ‘abc123’
This way, you’re pinned to a specific commit, reducing the risk of unexpected changes breaking your app. Just remember to update it periodically to get new features and fixes.
Having worked with GitHub-sourced gems, I can share some insights. While the Gemfile approach is common, you can also install directly via the command line:
gem install specific_gem --git https://github.com/user/repo.git
This method is useful for quick testing without modifying your Gemfile. However, be aware that this doesn’t track the gem in your project dependencies, which can lead to versioning issues down the line.
For production use, I strongly recommend sticking to released versions when possible. GitHub-sourced gems can introduce unexpected behavior, especially if the repo is actively developed. Always thoroughly test your application after introducing a gem from GitHub, regardless of the installation method.
hey there! to install a gem from github, just add this to ur Gemfile:
gem ‘gemname’, git: ‘https://github.com/user/repo.git’
then run bundle install. it’ll grab the latest from main. watch out tho, it might break stuff if the gem’s not stable yet. good luck!
Installing gems directly from GitHub can be quite useful, especially for accessing the latest features or fixes. I’ve done this several times in my projects. Here’s the process I follow:
In your Gemfile, specify the gem with its GitHub repository like this:
gem ‘gem_name’, git: ‘https://github.com/username/repository’
You can also target a specific branch, tag, or commit if needed:
gem ‘gem_name’, git: ‘https://github.com/username/repository’, branch: ‘develop’
After adding this to your Gemfile, run ‘bundle install’. Be cautious though, as using unreleased versions can introduce instability. Always test thoroughly before deploying to production.
