在macOS 10.15.7上安装Homebrew

可以使用以下步骤。由于macOS 10.15.7是一个较旧的版本，建议使用国内镜像源来加速安装过程。

安装前准备

1. 确保系统要求：

   • macOS 10.15.7

   • 已安装 Command Line Tools (CLT)

2. 安装 Command Line Tools：

   bash复制

   xcode-select --install

更新了git

gitee安装

/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"

进入界面

选择的2

继续

安装成功 但还需要重启终端 或者 运行 source /Users/skyhx/.zprofile   否则国内地址无法生效

source /Users/skyhx/.zprofile

查看 Homebrew 版本：

skyhx@HXdeMacBook-Pro bin % brew --version

Homebrew 4.4.16

权限问题

sudo chown -R $(whoami) $(brew --prefix)/*

sudo chown -R $(whoami) $(brew --prefix)/*

重置镜像源（恢复官方源）：

# 重置 brew.git
git -C "$(brew --repo)" remote set-url origin https://github.com/Homebrew/brew.git

skyhx@HXdeMacBook-Pro bin % python

Warning: You are using macOS 10.15.
We (and Apple) do not provide support for this old version.
It is expected behaviour that some formulae will fail to build in this old version.
It is expected behaviour that Homebrew will be buggy and slow.
Do not create any issues about this on Homebrew's GitHub repositories.
Do not create any issues even if you think this message is unrelated.
Any opened issues will be immediately closed without response.
Do not ask for help from Homebrew or its maintainers on social media.
You may ask for help in Homebrew's discussions but are unlikely to receive a response.
Try to figure out the problem yourself and submit a fix as a pull request.
We will review it but may or may not accept it.
