我正在关注Michael Hartl的Ruby on Rails教程＆amp;一切都运转良好，直到我到达this stage。
出于某种原因，当我尝试运行一个bundler或者rails命令时，它说它们没有安装，即使它们之前正在工作＆amp;我试图重新安装它们。
这可能与我的rvm gemset有关吗？我不确定如何检查rvmrc文件。
或者它可能与我的操作系统有关。我在Windows 7中托管的虚拟机上使用ubuntu 12.10。
提前感谢您的帮助。
如果有帮助的话，那就是应用的repo。

看起来你错过了last step of rvm install section of the tutorial：
$ rvm use 1.9.3@rails3tutorial2ndEd --create --default
Using /Users/mhartl/.rvm/gems/ruby-1.9.3 with gemset rails3tutorial2ndEd

此问题是由我对〜/ .bashrc文件所做的修改，以自定义终端中的提示。我已将PS1='\[\033[01;31m\]\W: \[\033[01;33m\]\$ \[\033[01;37m\]'放在〜/ .bashrc文件的底部。
我必须删除PS1='\[\033[01;31m\]\W: \[\033[01;33m\]\$ \[\033[01;37m\]'＆amp;完全卸载＆amp;删除RVM＆amp; Ruby来自我的系统＆amp;重新安装它们。我尝试rvm implode删除所有内容，但这一开始没有用，它说没有安装rvm！当我尝试source ~/.rvm/scripts/rvm时，我能够成功运行rvm implode。
我可以通过输入：
来自定义我的提示PS1='\[\033[01;31m\]\W: \[\033[01;33m\]\$ \[\033[01;37m\]'
source ~/.rvm/scripts/rvm
进入我的〜/ .bash_profile
