我正在开发一个使用 create-react-app 引导的 React 应用程序，它在 Chrome 中完美运行，但我无法让它在 IE11 中运行。
启动应用程序后，我从控制台收到以下错误:
对象不支持属性或方法“条目”
我花了几个小时在 Google 上搜索，试图找到解决方案，但推荐的解决方案都不起作用。
我尝试过的事情:
- 在
index.js顶部导入react-app-polyfill/ie11和react-app-polyfill/stable >
- 在
index.js顶部导入core-js/es/object/entries和core-js/features/object/entries> - Adding the following to
index.js:
if (!Object.entries) {
Object.entries = function( obj ){
var ownProps = Object.keys( obj ),
i = ownProps.length,
resArray = new Array(i); // preallocate the Array
while (i--)
resArray[i] = [ownProps[i], obj[ownProps[i]]];
return resArray;
};
}

请您参考如下方法:
您可以降级您的react-scripts版本。 在 package.json 中，更改为 "react-scripts": "3.2.0"。
