homebrew安装报错汇总

首先参考官网安装
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

1. 报错 curl: (7) Failed to connect to raw.githubusercontent.com port 443: Operation

先在浏览器输入这个地址:
https://raw.githubusercontent.com/Homebrew/install/master/install
看是否能打开，不能打开就是你网络有问题，不要问我哦。
能打开如下：

把这个网页保存名为brew_install.rb的文件，保存的位置你随便，只要自己能找到。
则在终端输入curl
$ curl
curl: try 'curl --help' or 'curl --manual' for more information
这样就没错，要是报错，那我就不知道了！
然后在终端进入存放这个文件的目录（这个不用我教吧），然后终端输入
ruby brew_install.rb
然后等安装homebrew吧！

2. 报错：fatal: unable to access 'https://github.com/Homebrew/brew/': Could not resolve proxy: proxy.server.com

I, too, just had this problem start all of a sudden within the past few days. It's definitely not Homebrew as mentioned above; I ended up doing

git config --global --unset http.proxy
git config --global --unset https.proxy
and then restarting my term session and it works again

3. 报错 Permission denied @ rb_file_s_symlink - (../../../Homebrew/completions/zsh/_brew, /usr/local/share/zsh/site-functions/_brew) Failed during: /usr/local/bin/brew update --force

Try to sudo chown -R $USER:admin /usr/local/*

4. 报错 sudo chown -R $USER:admin /usr/local/bin/brew illegal user name
