RN环境配置问题

安装前要先确认python环境是3.0以上

执行brew install watchman发生了以下的错误

Error: An unexpected error occurred during the `brew link` step

The formula built, but is not symlinked into /usr/local

Permission denied @ dir_s_mkdir - /usr/local/Frameworks

Error: Permission denied @ dir_s_mkdir - /usr/local/Frameworks

发现是python没有进行link并且不存在/usr/local/Frameworks文件夹

于是执行以下命令

sudo mkdir /usr/local/Frameworks

sudo chown $(whoami):admin /usr/local/Frameworks

brew link python

继续执行

brew install watchman

安装成功
