Download all gems dependencies

by

That’s precisely the problem I had.

After searching around for a while I found a solution that works using Bundler https://bundler.io/

Getting Gem with Dependencies:

  • Create a new Folder with a File named Gemfile.
  • Write a Source and the Gem you want to have the dependencies for into the File
  • Example:

    source “http://rubygems.org”
    gem ‘rails’, ‘3.2.1’

  • Open a Commandline at this Folder and Execute: bundle install
  • This should download and install all dependencies
  • Execute the Command bundle list if you wanna see it
  • Execute the Command bundle package
  • This should create the Directory Structure vendor/cache
  • Inside the cache directory are now all the dependencies you need for your gem

Install Gem on Machine without internet connection:

  • Copy the cache Folder to the Machine
  • Open a Commandline inside the Cache Folder and execute gem install –local Gemname.gem
  • Example:

gem install –local rails-3.2.1.gem
