ruby - 如何避免 "cannot load such file -- utils/popen"来自 OSX 上的 Homebrew 软件

Question

当我在终端中运行 brew 时出现错误:

 /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- utils/popen (LoadError)
from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'

这些是我的 gem 设置:

原始答案

问题主要发生在将 OS X 更新到 El Capitan (OS X 10.11) 或 macOS Sierra (macOS 10.12) 之后。

这是因为 El Capitan 或更高版本的 macOS 的文件权限问题 new SIP process .尝试更改 /usr/local 目录的权限:

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

如果仍然不起作用，请在终端 session 中使用这些步骤，一切都会好起来的:

cd /usr/local/Homebrew
git reset --hard origin/master
brew update

如果 /usr/local/Library/Homebrew 不起作用，请尝试 /usr/local/Homebrew。问题可能是 Homebrew 已过时。

上述命令不适用于 macOS High Sierra 或更高版本，如本 GitHub issue 中所述.你必须改为运行它:

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