I tried with all Ruby versions on rubyinstaller website. I also tried both versions on railsinstaller site. I been having same issue over and over with different versions of rubygems and such.

However When i do "rails new my_app --skip-bundle" it works, It also works when i manually go to the app folder and do bundle install. Just the bundle install while creating the app does not work at all.

Answer 1

I also had this problem with Ubuntu and OS X, I tried reverting rails to 4.2.4, it worked the first time, but the error persisted afterwards. The weird thing that I could normally 'bundle' or 'bundle install' inside the newly created app.

I tried playing with everything; rbenv, ruby, rails, bundler, etc nothing worked. I just reverted back the Rubygem version as you said and it worked like a charm!

Thank you! :)

Answer 2

I Actually found the problem which is Rubygem, I reverted back to 2.4 and it worked fine. The 2.5 was causing this problem. it had nothing to do with bundler or ruby version. Thank you everyone for your help.

Answer 3

`require': cannot load such file -- bundler (LoadError)

This error just means the bundler gem is missing for your current Ruby version.

So, you need to install the gem by doing this:

gem install bundler

and try again.

Update

If you are using rvm for managing your Ruby versions, Try doing the following to specify the Ruby version (2.2.3):

rvm use 2.2.3

Looking at the error message (C:/Ruby22-x64/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:128:in require': cannot load such file -- bundler (LoadError)), it's using Ruby 2.2.0 but not 2.2.3.

Answer 4

You don't have bundler installed. To install it run gem install bundler. Just like what K M Rakibul Islam said you must ensure you have bundler installed for each version of ruby. So you'll need to install bundler for ruby version 2.2.0.
