也许你可以试试下面的方法:

你的终端-> 编辑- > 配置文件首选项-> 标题和命令-> . 检查“作为登录shell运行命令” 完成

正如您所说，所显示的错误可能是以下错误。

RVM is not a function, selecting rubies with 'rvm use ...' will not work.

You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use `/bin/bash --login` as the command. 
Please visit https://rvm.io/integration/gnome-terminal/ for a example.

如上所述，只需在您的终端中输入'/bin/bash——login'(重启终端后)，然后键入命令'rvm use 1.9.3'(例如)，它将开始使用相同的版本。

只需执行命令'ruby -v'来确认RVM使用的是ruby的更新版本。

您需要运行以下命令

$ source ~/.rvm/scripts/rvm

然后运行这个

$ type rvm | head -n 1

如果你得到

rvm is a function

问题解决了。

您还需要运行user$ rvm requirements以查看操作系统的依赖项要求

我忘记提到你需要把这个代码到你~/。Bashrc或~/。ZSHRC文件，您将不需要再次编写此代码。

尽管你接受了一个答案，我还是想建议另一种方法。~ /。Bashrc在任何shell被打开之前被加载。在最后加上这一行，你不需要任何login shell的东西

以上答案都是正确的。但当我面对同样的问题时，解决方案如下:

Update ZSH. (Tried to update directly din't work for some reason. So uninstalled and reinstalled updated version from here) Set default shell as zsh (i.e. if you prefer zsh) using sudo chsh -s $(which zsh) $USER Ensure that the following code is at the bottom of your .zshrc after you have installed the latest RVM probably using CURL from official RVM site [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" source ~/.profile MOST IMPORTANT POINT: Ensure that in your .zshrc file every export to PATH is appended with :$PATH. Which i believe was the root of my problems even after following the above steps. post this all my problems of RVM Not being a function went away. If it still does not work, give some error trace over here. After a few hours of struggle to solve this issue, i'm sure i must have seen all related errors.

希望能有所帮助。干杯!
