cra 配置路径别名 @ 后，出现 ts 报错：找不到模块“@/App”或其相应的类型声明。ts(2307)

然后可以在 tsconfig.json 中配置 baseUrl 和 paths ：

{"compilerOptions": {"target": "es5","lib": ["dom","dom.iterable","esnext"],"allowJs": true,"skipLibCheck": true,"esModuleInterop": true,"allowSyntheticDefaultImports": true,"strict": true,"forceConsistentCasingInFileNames": true,"noFallthroughCasesInSwitch": true,"module": "esnext","moduleResolution": "node","resolveJsonModule": true,"isolatedModules": true,"noEmit": true,"jsx": "react-jsx","baseUrl": ".","paths": {"@/*": ["src/*"]}},"include": ["src"]
}
