ruby update with rvm错误消息(rvm要求失败)

Question

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

据我所知，我已经安装了rvm和homebrew。下面的命令行给出了一个完全不同的消息。

对不起，如果它很长，但我找不到答案。谢谢。

Answer 1

下面的命令行给出了一个完全不同的消息。

以下是错误消息：

第一条错误消息：

无法更新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正常工作，然后再继续。\n‘

第二条错误消息：

无法更新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正常工作，然后再继续。\n‘

所以它看起来像是一个安装自制软件的问题。我认为访问给出的链接，阅读在更新自制软件时遇到的常见问题将是值得尝试的事情。

Answer 2

我也有同样的问题，你有没有试着用sudo来运行它？

sudo rvm install ruby-2.1.2
