说明已安装配置完成，可以愉快的使用了~~~

下面内容是本人在2020年写的教程，作为参考

Homebrew 是一款 Mac OS 平台下的软件包管理工具，拥有安装、卸载、更新、查看、搜索等很多实用的功能。官方地址 https://brew.sh/

安装方法一：官方安装方式

在终端执行下面指令：

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
1

通常国内访问不到，会出现下面的问题

curl: (35) LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to raw.githubusercontent.com:443

建议解决方法：

1. 本地网络能访问https://raw.githubusercontent.com地址即可
2. 更换下载来源，即按照安装方法二（推荐）
3. 从github下载brew对应的仓库进行安装 https://github.com/Homebrew/brew

安装方法二

第一步：创建Homebrew文件夹

sudo mkdir /usr/local/Homebrew
1

第二步：获取Homebrew文件

sudo git clone https://mirrors.ustc.edu.cn/brew.git  /usr/local/Homebrew
1

第三步：创建快捷方式到/usr/local/bin目录

sudo ln -s /usr/local/Homebrew/bin/brew /usr/local/bin/brew
1

第四步：创建homebrew-core文件夹

sudo mkdir -p /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core
1

第五步：获取homebrew-core文件

sudo git clone https://mirrors.ustc.edu.cn/homebrew-core.git /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core
1

第六步：验证安装

1. 查看版本信息

brew --version
1

输出以下内容

Homebrew 2.2.17-105-g1aee867
Homebrew/homebrew-core (git revision dd2556; last commit 2020-05-25)

2. 更新操作

brew update
1

提示下面错误问题

mkdir: /usr/local/var/homebrew/locks: Permission denied
Error: Can’t create update lock in /usr/local/var/homebrew/locks!
Fix permissions by running:
sudo chown -R $(whoami) /usr/local/var/homebrew

解决方法

• 步骤1：sudo mkdir /usr/local/var
• 步骤2：sudo mkdir /usr/local/var/homebrew
• 步骤3：sudo chown -R $(whoami) /usr/local/var/homebrew

重新更新操作，指令 update 与 up 一样

brew up
1

输出下面内容，表示成功

Already up-to-date.

第六步：设置环境变量

echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.zshrc
1

macOS Catalina 默认为zsh，如果你使用的是bash，执行下面

echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile
1

问题记录

1、/usr/local/Homebrew is not writable

➜ local brew up
Error: /usr/local/Homebrew is not writable. You should change the
ownership and permissions of /usr/local/Homebrew back to your
user account:
sudo chown -R $(whoami) /usr/local/Homebrew

问题解决:

sudo chown -R $(whoami) /usr/local/Homebrew
