Module not found: Error: [CaseSensitivePathsPlugin] `D:\F\XX\project-SPH\app\src\pages\search\index.vue` does not match the corresponding path on disk `Search`.

The incorrect index.js code at this point is as follows:

// Where to configure routing
import Vue from 'vue ';
import VueRouter from 'vue-router ';//Using the plug-in
//Introduction of routing components
import Home from '@/pages/Home'
import Search from '@/pages/search'
import Login from '@/pages/Login'
import Register from '@/pages/Register'
//configure routing
export default new VueRouter({
//configure routing
        path : "/home",
        path: " /search",
        path: " /login",
        path: " /register",


At first, it was because Vue-router could not be installed. I suspected that Vue-router was not installed properly.

After an afternoon of Googling to find the cause, I decided to look at the code myself to see what the error meant. There are a total of 3 code: all point to the index.js file.

The first place: pointing to Search, I looked at the reference Search place, found written in lower case.

The second place: the reference to vue and vue-router, after careful observation, I found that I wrote an extra space.

After correction, it can be run again without any error.
