For a Rails app, I tried running $ bundle install. But, even after I ran $ gem install bundler, I got the same message.

this is what happened:

Run `bundle install` to install missing gems.
Davids-iMac-2:213calendar davidburton$ bundle install
ERROR: Gem bundler is not installed, run `gem install bundler` first.
Davids-iMac-2:213calendar davidburton$ gem install bundler
Successfully installed bundler-1.3.5
1 gem installed

rvm list

rvm rubies

   ruby-1.9.2-p290 [ x86_64 ]

检查您的主目录中的~/.bash_profile文件。

如果它存在，并且您不记得创建它，请将其内容复制到该文件并完全~/.bashrc删除。.bash_profile

默认情况下，rvm 会在安装.bash_profile后附加使用 rvm 功能更新路径的命令rvm。Ubuntu，一次只.bash_profile在它存在或不存在.bashrc时使用.bash_profile。这会导致PATH设置不正确，并且即使安装了 gem，也不会检测到它，因为它不在您的路径上。
