cannot load such file -- bundler/setup (LoadError)

I'm setting Rails 4 application with Ruby 2.0, but I'm getting "Web application could not be started" and get this trace:

cannot load such file -- bundler/setup (LoadError)

My apache2.conf is:

LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-4.0.19/buildout/apache2/mod_passenger.so
   PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-4.0.19
   PassengerDefaultRuby /usr/local/bin/ruby

bundle -v is:

Bundler version 1.3.5

ruby -v is:

ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]

gem env is:

echo $GEM_PATH is:

/usr/lib/ruby/gems/1.8:/usr/lib/ruby/gems/1.8

Shouldn't GEM_PATH be /usr/lib/ruby/gems/2.0?

Inside the virtual host in apache2.conf I added:

SetEnv GEM_HOME /usr/lib/ruby/gems/1.8

And now it is working.

Is it the right way to fix this?

Solution

  • It could be that there was a previous Ruby env installed on your system prior to your installation of 2.0? This might have had an existing GEM_PATH that lead to the /1.8 directory which the installation of version 2.0 simply kept.

    The problem you where likely having, then, was that Passenger/Apache was looking in the /2.0 directory when in fact the gems were in the /1.8 directory. Your explicitly telling apache to use the /1.8 directory thus makes sense to fix the problem.

    SetEnv GEM_HOME /usr/lib/ruby/gems/1.8

    You might also try using the Ruby Version Manager to handle multiple Ruby envs.
