brewupdate失败提示:/System/Library/Frameworks/Ruby.framework/。。。解决方法 ...

原作者: [db:作者] 来自: [db:来源] 收藏 邀请

情况大概是这样的:执行sudo brew update之后,提示:

 /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'
from /usr/local/Library/Homebrew/utils.rb:6:in `<top (required)>'
from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'
from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'
from /usr/local/Library/Homebrew/global.rb:9:in `<top (required)>'
from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'
from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'
from /usr/local/Library/brew.rb:16:in `<main>'

不管执行什么brew命令提示依旧,这种情况多发生在 El Capitan系统上,原因大概是更新失败,下面是stackoverflow找到的答案,亲测有效:

The problem mainly occurs after updating OS X to El Capitan (OS X 10.11). This is mainly because of file permission issues with file El Capitan’s new SIP process. Try changing permissions of/usr/local directory.

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

If it still doesn't work, use following steps and everything will be fine. This may be because homebrew is not updated.

1. open terminal  
2. $ cd /usr/local  
3. $ git reset --hard  
4. $ git clean -df
5. $ brew update
