问题描述

我的react应用无法在Internet Explorer 11上运行.在边缘和Chrome上运行正常.

My react app is not working on Internet explorer 11. It is working fine on edge and chrome.

我已经创建了很多文件,但我不认为我可以尝试npx create-react-app.(正如其他答案中针对类似问题所指出的那样)

I have already created a lot of files and i do not think I can try npx create-react-app.( As pointed out in the other answers for similar questions)

我已经在我的两个index.js文件中都包含了此文件,但是它不起作用.

I have included this in both my index.js file but it does not work.

import 'react-app-polyfill/ie11';

这是我得到的错误:

我查看了链接,他们要求解决方括号错误,但是当我看到代码时没有问题.

I have looked at the links and they ask to resolve a bracket error but there is no issue when I see the code.

这是我的package.json文件:

This is my package.json file:

{
      "name": "insurance_automation",
      "version": "0.1.0",
      "private": true,
      "dependencies": {
        "axios": "^0.18.0",
        "babel-polyfill": "^6.26.0",
        "bcryptjs": "^2.4.3",
        "body-parser": "^1.19.0",
        "config": "^3.1.0",
        "cors": "^2.8.5",
        "express": "^4.17.1",
        "jsonwebtoken": "^8.5.1",

        "node": "^11.15.0",

      },
      "scripts": {

        "test": "react-scripts test",

        "server": "nodemon server",
        "dev": "concurrently \"npm run server\" \"npm start\" "
      },
      "eslintConfig": {
        "extends": "react-app"
      },
      "browserslist": {
        "production": [
          ">0.2%",
          "not dead",
          "not op_mini all"
        ],
        "development": [
          "last 1 chrome version",
          "last 1 firefox version",
          "last 1 safari version"
        ]
      },
      "devDependencies": {
        "concurrently": "^4.1.0",
        "nodemon": "^1.19.1"
      }
    }

推荐答案

这对我有用.

更新package.json中的开发数组

Update the development array in package.json

    "development": [
      "ie 11",
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }

在src文件夹的index.js中添加以下代码

Add the below code in index.js in the src folder

// These must be the first lines in src/index.js
import 'react-app-polyfill/ie11';
import 'react-app-polyfill/stable';

然后删除node_modules文件夹并运行

Then delete the node_modules folder and run

npm install

默认情况下,IE不支持许多ES6 +功能.有关更多信息,请参考.

IE does not support a lot of ES6+ features by default. For more info, refer this.
