这个问题可能由于MacOS从10.11升级到10.12所导致,运行brew命令会提示如下错误:
/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 -- mach (LoadError)
首先打开终端进入 /usr/local路径,如果你的brew不是按照在如上路径,则进入如下目录:
cd `brew --prefix`
运行git status命令,如果Homebrew是dirty的,则运行如下命令:
git reset --hard && git clean -df
然后运行如下两个命令:
brew doctor brew update
然后brew会提示你因为用的是10.12运行时会报如下警告:
Formula file is modified!
所以需要安装以下几个包:
brew install gtk-mac-integration libepoxy py2cairo pygobject pygtk
我是做到这一步就ok了,如果brew还报错误,你可以尝试如下两条命令:
$ sudo rm /System/Library/Frameworks/Ruby.framework/Versions/Current $ sudo ln -s /System/Library/Frameworks/Ruby.framework/Versions/1.8 /System/Library/Frameworks/Ruby.framework/Versions/Current
good luck!
