报错原因：未配置 @符号为指定路径别名，直接使用导致

处理方法：

安装path模块：

npm install --save-dev @types/node

 修改vite.config.ts

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import path from 'path'
 
// https://vitejs.dev/config/
export default defineConfig({
  plugins: [vue()],
  server: {
    host: '0.0.0.0'
  },
  resolve: {
    alias: {
      '@': path.resolve(__dirname, 'src')
    }
  }
})

修改tsconfig.json：

配置 baseUrl、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,
    "baseUrl": ".",
    "paths": {
      "@/*": ["src/*"]
    }
  },
  "include": ["src/**/*.ts", "src/**/*.d.ts", "src/**/*.tsx", "src/**/*.vue"],
  "references": [{ "path": "./tsconfig.node.json" }]
}

最后重新运行项目
