所需的红宝石明显安装。我也试过了

Do you have rvm in your path? If not, add the following line to your ~.bashrc file...

你的路上有rvm吗？如果没有，请将以下行添加到〜.bashrc文件中......

PATH=$PATH:$HOME/.rvm/bin

Be sure and open and close the terminal after you all this. At the terminal you should be able to type 'echo $PATH' and see RVM listed.

完成所有这些后，请确保打开并关闭终端。在终端，您应该能够输入'echo $ PATH'并查看列出的RVM。
