在Windows环境下启动VUEJS报错,大致错误如下:

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR! 
npm ERR! Found: webpack@5.11.1

解决方法
降级npm到6版本

使用npx指定npm的版本

npx -p npm@6 npm i --legacy-peer-deps

Windows下启动vue项目
Windows下,打开DOS窗台,替换到VUE项目的根目录下,在其终端下运行如下命令:

npm install

npm run serve 或 npm run dev

出现类似下面的界面,则表示成功
