Load Error for rails-4.2.4 - will not load

Question

This is the error I get in my terminal when I am trying to spin up rails server or even when I input rails -v.

/Users/lukeduncan/.rbenv/versions/2.2.0/bin/rails:23:in `load': cannot load such file -- /Users/lukeduncan/.rbenv/versions/2.2.0/lib/ruby/gems/2.2.0/gems/rails-4.2.4/bin/rails (LoadError)
from /Users/lukeduncan/.rbenv/versions/2.2.0/bin/rails:23:in `<main>'

I have looked into the issue and noticed it may be because I have two versions of ruby installed. But not entirely sure so don't want to remove one just in case. When I gem install rails, it says it updates to the latest 4.2.4 but still does not load once I try to run a rails app or even trying to run rails -v. Other apps that I have also spin up the same error so it is not app specific.

Here is my gemfile.lock

Help would be much appreciated!

Answer 1

Figured it out. I had two versions of rails installed. Uninstalled both of them and railties as well. Reinstalled rails 4.2.4 and everything is working now.

Answer 2

You haven't published your Gemfile and Gemfile.lock, so I can only make assumptions. I assume that your Gemfile.lock contains a reference to rails 4.2.4, correct? If yes, make sure that you start rails from the directory where it resides; since Rails 3 it is Bundler-aware, so it executes rails command in the context of the current bundle.
