无法在MAC OS X el capitan中更新brew，并通过`require`不断收到Load错误.

问题描述

我不确定为什么会这样，但是我无法在我的MAC OS X El Capitan中更新brew.我做到了:

I am not sure why this is happening but I cannot update brew in my MAC OS X El Capitan. I did:

brew update

并得到:

warning: unable to unlink CONTRIBUTING.md: Permission denied
warning: unable to unlink SUPPORTERS.md: Permission denied
fatal: cannot create directory at '.github': Permission denied

要解决该问题，我对上面的命令进行了处理，但又遇到了更多问题:

to go over that issue I sudoed the above command but got further issues:

sudo brew update

    from /usr/local/Library/brew.rb:16:in `<main>'

现在每当我进行brew安装时，我都会得到:

now whenever I do brew install I get:

brew update

    from /usr/local/Library/brew.rb:16:in `<main>'

实际上，似乎只要执行任何操作(例如键入brew)，它都会收到相同的消息.有人知道如何解决这个问题吗?

in fact, it seems that whenever I do anything, like just type brew it gets the same message. Does anyone know how to fix this?

推荐答案

您不应将sudo与Homebrew一起使用.首先运行以下命令以确保您拥有/usr/local下的所有内容:

You shouldn’t use sudo with Homebrew. First run the following to ensure you own everything under /usr/local:

sudo chown -R $(whoami):admin /usr/local

更新的macOS版本的替代命令:

Alternative command for newer macOS version:

sudo chown -R $(whoami) $(brew --prefix)/*

然后将您的Homebr存储库重置为干净状态:

Then reset your Homebrew repo to a clean state:

cd /usr/local && git fetch && git reset --hard origin/master

它应该解决您的问题.

(如果在其他位置安装了Homebrew，请用$(brew --prefix)替换/usr/local)

(replace /usr/local with $(brew --prefix) if you installed Homebrew elsewhere)
