Failed to resolve import “@/views/index.vue“ from “src\router\index.ts“ vue3 routing configuration@file not found

 Introduce router in main.ts

import { createApp } from 'vue'
import './style.css'
import App from './App.vue'
import router from './router/index.js'
// 导入Unocss
import 'uno.css'

createApp(App).use(router).mount('#app')

Error message can't find path

[vite] Internal server error: Failed to resolve import "@/views/LoginView.vue" from "src\router\index.ts". Does the file exist?
  Plugin: vite:import-analysis
  File: D:/project/vue3-shopping/src/router/index.ts
  4  |      path: "/login",
  5  |      name: "Login",
  6  |      component: () => import("@/views/LoginView.vue"),

solve:

Modify vite.config.ts configuration

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
// 引入Unocss
import Unocss from 'unocss/vite';
import { presetUno, presetAttributify, presetIcons } from "unocss"
import path from 'path' // 需安装此模块

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [vue(),
    Unocss({ // 使用Unocss
      presets: [
        presetUno(),
        presetAttributify(),
        presetIcons()],
    })],

  resolve: {
    alias: {  // 这里就是需要配置resolve里的别名
      "@": path.join(__dirname, "./src"), // path记得引入
      // 'vue': 'vue/dist/vue.esm-bundler.js' // 定义vue的别名，如果使用其他的插件，可能会用到别名
    },
  }

})

Install the path module

Three ways, the first one I use.

npm install --save-dev @types/node

cnpm install --save-dev @types/node

yarn add @types/node -D

After the configuration is complete, run

 npm run dev

Solve it, sprinkle flowers!
