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

在vue項目中使用了vuex，但是項目跑起來之後控制台告警：

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

這是因為在引入vuex的時候有的地方首字母大寫有的地方首字母小寫引起的。具體代碼如下：
store/index.js引入代碼如下：

import Vuex from "Vuex";

在vue文件引入vuex的代碼如下：

import { mapMutations } from "vuex";

將index.js引入的vuex首字母改成小寫就解除了這個告警信息
