带有 rvm 错误消息的 ruby​​ 更新（rvm 要求失败）

Question

我是 ruby​​ 新手，我正在尝试使用 rvm 更新到 ruby​​ 的最新稳定版本。我收到以下错误消息：

据我所知，我已经安装了 rvm 和 homebrew。以下命令行给出了完全不同的消息。

对不起，如果它很长，但我无法在任何地方找到答案。谢谢。

Answer 1

以下命令行给出了完全不同的消息。

以下是错误消息：

第一条错误信息：

未能更新 Homebrew，请按照此处的说明进行操作： https://github.com/Homebrew/homebrew/wiki/Common-Issues 并确保 brew update 在继续之前有效。\n'

第二条错误信息：

未能更新 Homebrew，请按照此处的说明进行操作： https://github.com/Homebrew/homebrew/wiki/Common-Issues 并确保 brew update 在继续之前有效。\n'

所以看起来这是一个安装自制软件的问题。我认为转到给出的链接并阅读更新自制软件时遇到的常见问题是值得尝试的。

Answer 2

我遇到了同样的问题，你试过用 sudo 运行它吗？

sudo rvm install ruby-2.1.2
