对于其他试图修复PATH变量的shell新手

在遵循已接受答案中的说明后，如果需要，检查并修改PATH变量:

env | grep PATH 

如果你在任何地方看到“rvm”，你需要弄清楚你在哪里设置PATH并修改。我把它设置在3个文件-所以检查所有以下文件:

vim .bashrc  

使用dd命令删除文件中引用rvm的行。:wq保存并退出。 Source .bashrc来“重载”

对.profile和.bash_profile重复这个过程(从vim命令开始)

注意，如果你通过apt-get安装RVM，你必须运行一些比RVM implode或apt-get remove ruby-rvm更深入的步骤来真正卸载它。

参见“在Ubuntu上安装RVM”。

如果其他答案不能完全为您删除RVM, RVM的故障排除页面包含此部分:

How do I completely clean out all traces of RVM from my system, including for system wide installs? Here is a custom script which we name as cleanout-rvm. While you can definitely use rvm implode as a regular user or rvmsudo rvm implode for a system wide install, this script is useful as it steps completely outside of RVM and cleans out RVM without using RVM itself, leaving no traces. #!/bin/bash /usr/bin/sudo rm -rf $HOME/.rvm $HOME/.rvmrc /etc/rvmrc /etc/profile.d/rvm.sh /usr/local/rvm /usr/local/bin/rvm /usr/bin/sudo /usr/sbin/groupdel rvm /bin/echo "RVM is removed. Please check all .bashrc|.bash_profile|.profile|.zshrc for RVM source lines and delete or comment out if this was a Per-User installation."

根据RVM的故障排除文档“如何从系统中完全清除RVM的所有痕迹，包括系统范围的安装?”：

Here is a custom script which we name as 'cleanout-rvm'. While you can definitely use rvm implode as a regular user or rvmsudo rvm implode for a system wide install, this script is useful as it steps completely outside of RVM and cleans out RVM without using RVM itself, leaving no traces. #!/bin/bash /usr/bin/sudo rm -rf $HOME/.rvm $HOME/.rvmrc /etc/rvmrc /etc/profile.d/rvm.sh /usr/local/rvm /usr/local/bin/rvm /usr/bin/sudo /usr/sbin/groupdel rvm /bin/echo "RVM is removed.

除了@tadman的回答，我删除了/usr/local/bin以及文件/etc/profile.d/rvm.中的包装器

包装材料包括:

erb
gem
irb
rake
rdoc
ri
ruby
testrb
