踩坑记录：

1.执行npm install -g yarn时候报错

(base) zoes-MacBook-Pro:~ zoe$ sudo npm install -g yarn

> yarn@1.22.18 preinstall /usr/local/lib/node_modules/yarn
> :; (node ./preinstall.js > /dev/null 2>&1 || true)

npm ERR! code EEXIST
npm ERR! syscall symlink
npm ERR! path ../lib/node_modules/yarn/bin/yarn.js
npm ERR! dest /usr/local/bin/yarn
npm ERR! errno -17
npm ERR! EEXIST: file already exists, symlink '../lib/node_modules/yarn/bin/yarn.js' -> '/usr/local/bin/yarn'
npm ERR! File exists: /usr/local/bin/yarn
npm ERR! Remove the existing file and try again, or run npm
npm ERR! with --force to overwrite files recklessly.

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/zoe/.npm/_logs/2022-04-26T07_29_58_787Z-debug.log

尝试加上--force to overwrite files recklessly，依旧报错

进入/usr/local/bin 目录删除yarn和yarnpkg后重新执行命令，解决

2.执行brew tap homebrew/cask-versions时报错

参考博客：https://www.cnblogs.com/fanstudy/p/13795885.htmlhttps://www.cnblogs.com/fanstudy/p/13795885.html

解决方案：

首先安装homebrew-cask：

git clone https://mirrors.ustc.edu.cn/homebrew-cask.git

/usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask

其次安装homebrew-cask-versions：

git clone https://gitee.com/excelsi0r/homebrew-cask-versions.git

/usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask-versions

3.执行brew install --cask zulu11出错

(base) zoes-MacBook-Pro:~ zoe$ brew install --cask zulu11
Error: Cask 'zulu11' is unavailable: No Cask with this name exists.

解决方案：

直接去官网下载 Zulu.jdk

下载第一个.dmg的即可，下载后打开安装即可

4.执行npx react-native init AwesomeProject时出错

error Error: Failed to install CocoaPods dependencies for iOS project, which is required by this template.
Please try again manually: "cd ./AwesomeProject/ios && pod install".
CocoaPods documentation: https://cocoapods.org/

解决方案 ：首先安装一下Xcode（如果你和我一样把Xcode删了>）

然后尝试一下修改cocoapod镜像：

添加ruby镜像时出错，需要更新ruby：

但是我上面两个方法都没成功
