bundler/setup (LoadError)

Question

I cloned a repository and tried to run rails s. However, I received the following error:

/Users/me/.rbenv/versions/1.9.3-p547/lib/ruby/1.9.1/rub         


        

Answer 1

On the mac, it is possible that you installed gems to ./vendor/bundle in order to avoid to use SUDO. You can find it if you run gem install bundler and at the end of the output you see the following:

Using turbolinks-source 5.1.0
Using turbolinks 5.1.0
Using uglifier 4.1.4
Bundle complete! 13 Gemfile dependencies, 68 gems now installed.
Bundled gems are installed into `./vendor/bundle`

If this is the case than in your app root directory delete the bundle directory. After this run the following commands:

[sudo] gem install bundler
bundle install

It solved the problem for me

Answer 2

You likely have bundler gem missing.

To get it to work run (first command may need be executed with sudo, depending on your environment):

[sudo] gem install bundler
bundle install
