我得到以下错误。

我的bash配置文件如下：#start＃.bash_profile
# Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs #PATH=$PATH:$HOME/bin PATH=$HOME/.gems/bin:$HOME/bin:$PATH GEM_HOME=$HOME/.gems GEM_PATH=$HOME/.gems:/usr/lib/ruby/gems/1.8 export PATH GEM_HOME GEM_PATH #export PATH #END
另外，供您参考，我的gem环境如下：

请建议出现什么问题以及如何纠正错误。 提前致谢。
尝试观察铁路gem的路径：
bundle show railties
如果失败，请尝试手动安装gem：
gem install railties
尝试安装通用ruby版本：
sudo apt-get install ruby-dev
然后尝试，
sudo gem install railties
