如何在没有配置文件的情况下修复导入/导出 babel-eslint？

Question

当我点击 npm start 时，出现以下错误：

Parsing error: 'import' and 'export' may only appear at the top level

当我查看此错误时，他们说我需要更新 eslint 配置文件，并在解析器选项中设置为 true 等等。但是，我没有 eslint 配置文件，我的包 json 如下所示：

{

  "name": "client",

  "version": "0.1.0",

  "private": true,

  "dependencies": {

    "@material-ui/core": "^3.6.1",

    "@material-ui/icons": "^3.0.1",

    "material-icons-react": "^1.0.4",

    "react": "^16.6.3",

    "react-dom": "^16.6.3",

    "react-scripts": "2.1.1",

    "truffle-contract": "^4.0.0-beta.1",

    "web3": "^1.0.0-beta.36"

  },

  "scripts": {

    "start": "react-scripts start",

    "build": "react-scripts build",

    "test": "react-scripts test",

    "eject": "react-scripts eject"

  },

  "eslintConfig": {

    "extends": "react-app"

  },

  "browserslist": [

    ">0.2%",

    "not dead",

    "not ie <= 11",

    "not op_mini all"

  ]

}

更新：整个错误：

./src/App.js

  Line 131:  Parsing error: 'import' and 'export' may only appear at the top level

  129 |     );

  130 | 

> 131 |   export default App;
