vue 运行时报错 There are multiple modules with names that only differ in casing.

There are multiple modules with names that only differ in casing.

出现有时大写, 有时小写的盘符​

* D:\www\ktcargo\node_modules\_css-loader@3.6.0@css-loader\dist\runtime\api.js

    Used by 16 module(s), i. e.

* d:\www\ktcargo\node_modules\_css-loader@3.6.0@css-loader\dist\runtime\api.js

    Used by 54 module(s), i. e.

    d:\www\ktcargo\node_modules\_css-loader@3.6.0@css-loader\dist\cjs.js??ref--9-oneOf-3-1!d:\www\ktcargo\node_modules\_postcss-loader@3.0.0@postcss-loader\src\index.js??ref--9-oneOf-3-2!d:\www\ktcargo\node_modules\_sass-loader@10.2.1@sass-loader\dist\cjs.js??ref--9-oneOf-3-3!d:\www\ktcargo\src\styles\vab.scss

后来细想一下, 是自建立的cmd, 入口写在了 d:\www\ktcargo

windows盘符是大小的, 正确写法是D:\www\ktcargo

这种小小地方, 有时很难找!
