Your bundle is locked to rest_client (1.8.3), 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 rest_client (1.8.3) has removed it. You'll need to update your bundle to a different version of rest_client (1.8.3) that hasn't been removed in order to install.

  • How does your `Gemfile` look like? Is there a line like `gem 'rest_client'`? – spickermann Oct 24 '17 at 11:12

rest_client is deprecated. That's why your bundler couldn't find it in any source. Either you have to install it from git or you have to use rest-client which is in the source (RubyGems.org). But your Gemfile.lock file has rest_client locked. Follow these steps:

  1. Remove your Gemfile.lock file.
  2. Remove rest_client from your Gemfile.
  3. Add gem 'rest-client' to your Gemfile.
  4. bundle install.

Your problem is solved hopefully.
