一、安装node

Node 版本要求

框架安装需要 Node.js ^16.17.0 || >=16。你可以使用 nvm 或 nvm-windows 在同一台电脑中管理多个 Node 版本。

二.安装watchman

Watchman是facebook的一个开源项目，它开源用来监视文件并且记录文件的改动情况，当文件变更它可以触发一些操作,例如执行一些命令等等。
在使用React Native时，官方推荐推荐安装Watchman，否则你可能会遇到一个Node.js监视文件系统的BUG。

$ brew install watchman

可能会报如下错误，大概就是我Mac的系统版本太新了，不支持当前Mac系统版本

解决办法

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

source ~/.zshrc

brew update

然后再安装Watchman

查看安装版本
