我得到这个错误使用RVMRVM：如何将默认路径更改为主目录？
[email protected]:22:59 ~ $ rvm install 1.9.3
mkdir: cannot create directory ‘/usr/local/rvm/log/ruby-1.9.3-p448’: Permission denied
Could not detect ruby version/name for installation, please be more specific.
如何更改默认的目录/home/kithokit/.rvm
你可以通过执行这个脚本
#!/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."

确保重新启动机器以摆脱任何指向o的环境变量ut到旧的位置（是的，在系统安装时需要）。
