问题:找不到模块“@/…”或其相应的类型声明

解决方法：
tsconfig.json 中添加配置

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