我看过很多相关的问题和帖子，但我无法解决我的问题。我正在运行 El Capitan，我想让 Homebrew 和 Ruby 运行。但是，如果我想运行 Homebrew，我会收到以下权限错误：

bio89093:~ jonbra$ brew doctor
/Library/Ruby/Site/2.0.0/rubygems.rb:1219:in `register_default_spec': undefined method `default_gems_use_full_paths?' for Gem:Module (NoMethodError)

我曾尝试使用 RVM 安装单独版本的 Ruby，但它似乎需要 Homebrew...

【解决方案1】：

尝试再次删除并安装自制软件：

卸载：

$ cd `brew --prefix`
$ rm -rf Cellar
$ brew prune
$ rm -rf Library .git .gitignore bin/brew README.md share/man/man1/brew
$ rm -rf ~/Library/Caches/Homebrew

然后：

$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

谢谢，但仍然出现同样的错误... bio89093:local jonbra$ ruby -e "$(curl -fsSL raw.githubusercontent.com/Homebrew/install/master/install)" /Library/Ruby/Site/2.0.0/rubygems .rb:1219:in register_default_spec': undefined method default_gems_use_full_paths？对于 Gem:Module (NoMethodError) ...

【解决方案2】：

我遇到了类似的问题。在你的终端试试这个：

cd "$(brew --repo)" && git fetch && git reset --hard origin/master && brew update

他们在 brew github 页面的顶部有一个注释，按照这些说明解决了我的问题。

【解决方案3】：

确保下面的文件夹不包含额外的文件和文件夹，

/Library/Ruby/Site/2.0.0

为此，请运行，

$cd /Library/Ruby/Site/2.0.0
$rm -rf /Library/Ruby/Site/2.0.0/*
$/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

有时您可能会遇到 SSL 错误，在这种情况下，请在 curl 中添加 -k 选项。

$/usr/bin/ruby -e "$(curl -k -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
