VsCode 执行 npm run dev 失败

今天在执行 npm run dev 时 ,启动不成功 .

异常代码

    Note that the development build is not optimized.
    To create a production build, run npm run build.

解决方法 :

方法一 :

在环境变量Path中添加 C:\Windows\System32

1.右键此电脑-- 属性 – 高级系统设置 – 高级 – 环境变量 – 系统变量，找到Path，双击新建路径。

2.重启项目就OK了

如果不是以上问题 ,可以看一下,下面的文章
