无法在 MAC OS X el capitan 中更新 brew 并不断收到“require”加载错误

Question

我不确定为什么会这样，但我无法在 MAC OS X El Capitan 中更新 brew。我做到了：

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

为了解决这个问题，我对上面的命令进行了 sudo，但遇到了更多问题：

sudo brew update

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

现在，每当我执行 brew install 时，我都会得到：

brew update

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

事实上，似乎无论何时我做任何事情，比如键入 brew，它都会收到相同的消息。有谁知道如何解决这个问题？

你不应该将 sudo 与 Homebrew 一起使用。首先运行以下内容以确保您拥有 /usr/local 下的所有内容：

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

较新 macOS 版本的替代命令：

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

然后将您的 Homebrew 存储库重置为干净状态：

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

它应该可以解决您的问题。

（如果您在其他地方安装了 Homebrew，请将 /usr/local 替换为 $(brew --prefix)）
