vite ts 找不到模块@/xxxx 或其相应的类型声明

一、找到项目下的 tsconfig.json

二、添加如图所示baseUrl和paths

{
  "compilerOptions": {
    "target": "ESNext",
    "useDefineForClassFields": true,
    "module": "ESNext",
    "moduleResolution": "Node",
    "strict": true,
    "jsx": "preserve",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "esModuleInterop": true,
    "lib": ["ESNext", "DOM"],
    "skipLibCheck": true,
    "noEmit": true,
    //解析非相对模块的基础地址，默认是当前目录
	"baseUrl": "./",
	//路径映射，相对于baseUrl
	"paths": {
		"@/*": ["./src/*"]
	},
  },
  "include": ["src/**/*.ts", "src/**/*.d.ts", "src/**/*.tsx", "src/**/*.vue"],
  "references": [{ "path": "./tsconfig.node.json" }]
}

三、找到vite.config.ts

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import path from 'path' //引入path模块

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [vue()],
  resolve: {
    alias: {
      vue: "vue/dist/vue.esm-bundler.js",
      '@': path.resolve(__dirname, 'src'), //配置@路径
    }
  }
})
