How can I specify a local gem in my Gemfile

Question

I'd like Bundler to load a local gem. Is there an option for that? Or do I have to move the gem folder into the .bundle directory?

Hello @kartik,

In order to use local gem repository in a Rails project, follow the steps below:

1. Check if your gem folder is a git repository (the command is executed in the gem folder)

   git rev-parse --is-inside-work-tree

2. Getting repository path (the command is executed in the gem folder)

   git rev-parse --show-toplevel

3. Setting up a local override for the rails application

   bundle config local.GEM_NAME /path/to/local/git/repository

   where GEM_NAME is the name of your gem and /path/to/local/git/repository is the output of the command in point 2

4. In your application Gemfile add the following line:

   gem 'GEM_NAME', :github => 'GEM_NAME/GEM_NAME', :branch => 'master'

5. Running bundle install should give something like this:

   Using GEM_NAME (0.0.1) from git://github.com/GEM_NAME/GEM_NAME.git (at /path/to/local/git/repository) 

   where GEM_NAME is the name of your gem and /path/to/local/git/repository from point 2

6. Finally, run bundle list, not gem list and you should see something like this:

   GEM_NAME (0.0.1 5a68b88)

   where GEM_NAME is the name of your gem

Hope it helps!!

Thank You!
