【问题描述】：

我尝试通过 RVM 安装 Ruby 2.0。好像我安装了 Ruby 没有任何问题。但是，当我输入 ruby -v 时，什么也没有出现。我认为命令 ruby 尚未设置。

我想知道如何使用“ruby -v”。

【问题讨论】：

你source ~/.rvm/scripts/rvm了吗？

标签： ruby installation rvm

【解决方案1】：

你应该有类似的东西

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

在您的 .profile 文件中。

如果它在那里，你可能没有启动一个新的登录 shell，因为它被添加了，所以只需手动获取它。

那么你应该会看到一些与 ruby 相关的路径

echo $PATH
