vue使用vuex后报警：There are multiple modules with names that only differ in casing.

在vue项目中使用了vuex，但是项目跑起来之后控制台告警：

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:

• F:\dch\workspace\PMS\node_modules\Vuex\dist\vuex.esm.js
  Used by 1 module(s), i. e.
  F:\dch\workspace\PMS\node_modules\babel-loader\lib\index.js!F:\dch\workspace\PMS\node_modules\eslint-loader\index.js??ref--0!F:\dch\workspace\PMS\src\store\index.js
• F:\dch\workspace\PMS\node_modules\vuex\dist\vuex.esm.js
  Used by 9 module(s), i. e.
  F:\dch\workspace\PMS\node_modules\babel-loader\lib\index.js!F:\dch\workspace\PMS\node_modules\vue-loader\lib\selector.js?type=script&index=0!F:\dch\workspace\PMS\src\views\server.vue

这是因为在引入vuex的时候有的地方首字母大写有的地方首字母小写引起的。具体代码如下：
store/index.js引入代码如下：

import Vuex from "Vuex";

在vue文件引入vuex的代码如下：

import { mapMutations } from "vuex";

将index.js引入的vuex首字母改成小写就解除了这个告警信息
