今天在 MacBook 上安装 Homebrew,结果中间断了网,想重新卸载重装,结果一直卸载失败。问题现象如下:
问题现象
卸载时错误如下:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
Failed to locate Homebrew!
重装时错误如下:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
It appears Homebrew is already installed. If your intent is to reinstall you
should do the following before running this installer again:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
The current contents of /usr/local are bin Cellar etc Frameworks Homebrew include lib opt sbin share var
问题分析
google 后发现有这样的问题讨论帖子,有人建议执行:
rm -rf /usr/local/.git
后再重新安装。貌似这个解决方案有很多人成功了。不过我这么做后还是出现卸载失败。
粗粗想了一下,大概因为是断网造成的,断网导致了安装不完全,在安装目录产生了一些不完整的目录文件。
查找了一下,找到一个目录
执行:
mdfind homebrew
找到:
/usr/local/Homebrew
cd
到/usr/local/
目录,ls -al
了一下,发现还存在几个安装时出现过的目录名字,于是一并删除了。
下面是当初安装时的提示信息:
? local ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
==> This script will install:
/usr/local/bin/brew
/usr/local/share/doc/homebrew
/usr/local/share/man/man1/brew.1
/usr/local/share/zsh/site-functions/_brew
/usr/local/etc/bash_completion.d/brew
/usr/local/Homebrew
==> The following new directories will be created:
/usr/local/Cellar
/usr/local/Homebrew
/usr/local/Frameworks
Press RETURN to continue or any other key to abort
下面是 ls -al
的信息:
? local ls -al
total 0
drwxr-xr-x 13 Ade wheel 442 9 12 19:15 .
[email protected] 12 root wheel 408 12 5 2015 ..
drwxrwxr-x 2 Ade admin 68 9 12 19:15 Cellar
drwxrwxr-x 2 Ade admin 68 9 12 19:15 Frameworks
drwxrwxr-x 3 Ade admin 102 9 12 19:15 Homebrew
问题解决
删除 Homebrew 安装时产生的目录
rm -rf Cellar Frameworks Homebrew
重新执行安装命令:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
按照提示 回车
继续执行,
最后出现下面的提示表示安装成功
==> Installation successful!
==> Next steps
Run `brew help` to get started
Further documentation: https://git.io/brew-docs
==> Homebrew has enabled anonymous aggregate user behaviour analytics
Read the analytics documentation (and how to opt-out) here:
https://git.io/brew-analytics
执行 brew help
,正常显示命令帮助,Nice !
