问题描述

问 题

warning in ./~/vue-style-loader/lib/addStylesClient.js

There are multiple modules with names that only differ in casing.
This can lead to unexpected behavior when compiling on a filesystem with other case-semantic.
Use equal casing. Compare these module identifiers:

• E:WebProjectUFAPPDYJJnode_modulesvue-style-loaderlibaddStylesClient.js

  Used by 4 module(s), i. e.
  E:\WebProject\UFAPP\DYJJ\node_modules\vue-style-loader\index.js!E:\WebProject\UFAPP\DYJJ\node_modules\css-loader\index.js?{"minimize":false,"sourceMap":false}!E:\WebProject\UFAPP\DYJJ\node_modules\vue-loader\lib\style-compiler\index.js?{"vue":true,"id":"data-v-f7c02f2c","scoped":false,"hasInlineConfig":false}!E:\WebProject\UFAPP\DYJJ\node_modules\vue-loader\lib\selector.js?type=styles&index=0!E:\WebProject\UFAPP\DYJJ\src\App.vue

warning in ./~/vue-style-loader/lib/listToStyles.js

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

Use equal casing. Compare these module identifiers:

• E:WebProjectUFAPPDYJJnode_modulesvue-style-loaderliblistToStyles.js

  Used by 1 module(s), i. e.
  E:\WebProject\UFAPP\DYJJ\node_modules\vue-style-loader\lib\addStylesClient.js

解决方案

There are multiple modules with names that only differ in casing.
有多个模块同名仅大小写不同
This can lead to unexpected behavior when compiling on a filesystem with other case-semantic.
这可能导致在一些文件系统中产生不是预期的行为
Use equal casing.
使用唯一的写法

猜测是因为你的文件名和引用不一致，举个例，文件名是App.js，但是你引用的时候是写的app.js
