Cannot run Unicorn with Ruby 2.0
ruby, ruby-2.0, ruby-on-rails, unicorn
Solution
Try reinstalling the gem with 2.0.0.
The problem must have been caused by the fact the gem was installed in 1.9.3.
Problem
On my ubuntu machine, I can run unicorn on ruby 1.9.3, however, it does not seem to work with ruby 2.0. Any idea why? ``` root@dev:/home/karan# rvm use 1.9 Using /usr/local/rvm/gems/ruby-1.9.3-p429 root@dev:/home/karan# unicorn -v unicorn v4.6.3 root@dev:/home/karan# rvm use 2.0 Using /usr/local/rvm/gems/ruby-2.0.0-p195 root@dev:/home/karan# unicorn -v /usr/local/rvm/rubies/ruby-2.0.0-p195/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require': cannot load such file -- unicorn/launcher (LoadError) from /usr/local/rvm/rubies/ruby-2.0.0-p195/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require' from /usr/bin/unicorn:3:in `<main>' ```
