一.nginx 安装参考：(亲测有用)

​​​​​​Mac 安装 brew（最新教程，绝对可行，一行代码搞定，不报错） - LeeHua - 博客园

nginx按照👆参考方法安装即可

二.switchhosts 在官网上下载即可

看准mac下载位置--我之前抓着第一条下载了好几遍，怀疑人生==

三.nginx配置
brew info nginx
#网页目录： /opt/homebrew/var/www
#默认配置文件：/opt/homebrew/etc/nginx/nginx.conf
#会被加载的配置文件:  /opt/homebrew/etc/nginx/servers/

 用命令行  open /opt/homebrew/etc/nginx 打开文件

配置nginx.conf

ps：连接不同wifi IP会不一样。

四.配置switchhosts 

五。配置完后，重启电脑，运行switchhosts，nginx,运行项目
