And this command also works fine: ``` ruby -e 'require "webmock/rspec"' ``` I doubt that there is something wrong with my bundler. But when I check my bundle. ``` more /usr/local/bin/bundle ``` I saw: ``` #!/usr/local/bin/ruby ``` This means bundle is using the same ruby as I test. Here is the ruby version I am using: ``` ruby 1.9.3p392 (2013-02-22 revision 39386) [x86_64-linux] ```
