安装brew遇到的问题解答,Operation not permitted问题解决
一,安装brew

1,安装brew

curl -LsSf http://github.com/mxcl/homebrew/tarball/master | sudo tar xvz -C/usr/local –strip 1

2,安装完成后执行

brew

提示:Please run brew update!

3,按照提示更新,执行

brew update

报错:Error: /usr/local must be writable!

4,赋给/usr/local目录权限,执行sudo chown -R $(whoami) /usr/local,即

sudo chown -R fxp /usr/local

其中fxp为系统当前用户名。

5,再次执行

brew update

提示:

HEAD is now at c3f959d Merge pull request #1542 from woodruffw/deprecate-utils-json

To restore the stashed changes to /usr/local run:

‘cd /usr/local && git stash pop’

Homebrew no longer needs to have ownership of /usr/local. If you wish you can

return /usr/local to its default ownership with:

sudo chown root:wheel /usr/local

6,按照提示删除/usr/local/share/doc/homebrew,执行

rm -r -f /usr/local/share/doc/homebrew

7,再次执行

brew update

其实这样依旧不能解决安装失败的问题,如果项顺利的安装成功,可能是你第一次安装失败了,又安装了一次,下面是撤销安装的命令,以及重新安装的命令
在brew update的时候出现报错:Error: /usr/local must be writable! 错误,对于高版本的OS来说,是解决不了的,会报chown: /usr/local: Operation not permitted错误。

后来在https://stackoverflow.com/questions/46459152/cant-chown-usr-local-for-homebrew-in-osx-10-13-high-sierra网页上给出了解决办法,下面简单总结一下:

先卸载已安装的homebrew,命令如下:

/usr/bin/ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)”
然后重新安装:
/usr/bin/ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”

博主第一次写的博客,万分激动,这个问题弄了好久

补充:
如果新的本子没有安装好brew
可以这样搞
/usr/bin/ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”
