Mac下安装homebrew，并解决brew慢到不行的问题

最简单的安装homebrew

运行命令即可： /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
如果网络太卡，一直动不了的话，可以试试：
1）早上用WIFI，避免晚上和下午
2）再不行，就用手机热点，移动的不错，挺快，就是流量用得厉害，快1G
3）再不行？试试下面的方法，使用了国内的源，稳定性好点，就是偶尔也会炸锅。

装好后，建议使用国内的最受欢迎的源：https://mirrors.ustc.edu.cn/

cd "$(brew --repo)"
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git

cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git

echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile
source ~/.bash_profile
brew update

使用Launchrocket管理MacOS的服务 - 开机自动启动服务

注意：httpd（或apache）需要勾选“as root”才行

方法2: 安装homebrew（国内源-阿里云）

下载安装脚本（已优化）：https://download.csdn.net/download/qq285744011/12564109
cd ~/Downloads/
chmod 0777 ./brew_install_from_aliyun.sh
./brew_install_from_aliyun.sh

安装时，如果命令执行中卡在下面信息：

==> Tapping homebrew/core
Cloning into '/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core'...

请Control + C中断脚本执行如下命令：

cd "$(brew --repo)/Library/Taps/"
mkdir homebrew && cd homebrew
git clone git://mirrors.ustc.edu.cn/homebrew-core.git

cask 同样也有安装失败或者卡住的问题，解决方法也是一样：

cd "$(brew --repo)/Library/Taps/"
cd homebrew
git clone https://mirrors.ustc.edu.cn/homebrew-cask.git

成功执行之后继续执行前文的安装命令:

cd ~/Downloads/
./brew_install_from_aliyun.sh

以上几个命令，均参考自： https://zhuanlan.zhihu.com/p/90508170

安装以后，更新brew的源为“阿里云”

cd "$(brew --repo)"
git remote set-url origin https://mirrors.aliyun.com/homebrew/brew.git

cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.aliyun.com/homebrew/homebrew-core.git

brew update

再做些改动

brew install brew-cask-completion
sudo nano ~/.bash_profile

添加以下内容：

if [ -f ~/.bashrc ]; then
source ~/.bashrc
fi
export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles

上述的脚本内容为：

#!/bin/bash
set -u

# First check if the OS is Linux.
if [[ "$(uname)" = "Linux" ]]; then
  HOMEBREW_ON_LINUX=1
fi

# On macOS, this script installs to /usr/local only.
# On Linux, it installs to /home/linuxbrew/.linuxbrew if you have sudo access
# and ~/.linuxbrew otherwise.
