【问题描述】：
我在 Ubuntu 11.10 上运行 RubyMine 4，RubyMine 中的一切都很好，我可以运行服务器、开发等等。但是，当我需要在命令行上工作时，我什么也做不了。 .
我 cd 到我的应用程序目录，然后我尝试：
$ rails s
我明白了：
The program 'rails' is currently not installed. You can install it by typing:
sudo apt-get install rails
奇怪，怎么没有安装，而我在RubyMine IDE中可以正常工作！
我需要使用命令行来卸载 gem，发现我不能正常使用命令行..
sam@ubuntu:~/Documents/RoR/course_builder$ gem uninstall 'capybara-firebug'
ERROR: While executing gem ... (Gem::InstallError)
cannot uninstall, check `gem list -d capybara-firebug`
$ gem list -d 会给我：
*** LOCAL GEMS ***
那里没有宝石..
如果我输入：
$ bundle install
我明白了：
/usr/lib/ruby/vendor_ruby/bundler/rubygems_ext.rb:8:in `require': no such file to load -- rubygems (LoadError)
from /usr/lib/ruby/vendor_ruby/bundler/rubygems_ext.rb:8
from /usr/lib/ruby/vendor_ruby/bundler.rb:11:in `require'
from /usr/lib/ruby/vendor_ruby/bundler.rb:11
from /usr/bin/bundle:4:in `require'
from /usr/bin/bundle:4
尽管 RubyMine 中的 bundle install 工作正常
那么，我在这里缺少什么？！为什么我不能使用命令行..？
这是我的 gem 环境：

如果我输入 ruby -v
sam@ubuntu:~/Documents/RoR/course_builder$ ruby -v
ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-linux]
【问题讨论】：
-
输入“rvm”有什么作用？ ruby -v 怎么样？
-
请参阅上面的编辑以获得 rvm 结果，ruby -v 结果
-
你真的安装了rvm吗？您是否在命令行中
rvm use xxxx选择了您的 Ruby 和 gemset？ -
您能否也发布您的 .bashrc 或 .bash_profile（如果您更改了它们）？
-
感谢 Dave，我使用 rvm use 来选择 ruby 版本和 gemset，它运行良好.. 很抱歉，但是，我是 rvm 的新手..
