javascript - react 16 : script1002 syntax error on IE11 and below

Question

在 IE11 及更低版本上查看我的应用时出现此错误。该应用程序还返回一个白页。

更糟糕的是，控制台没有显示行号来指示问题所在/位置。这使得很难找出问题所在。我正在使用 Webpack 4 和 babel-polyfill。

谁能指出我正确的方向？

Webpack 配置

const HtmlWebPackPlugin = require("html-webpack-plugin");
const ExtractTextPlugin = require("extract-text-webpack-plugin");

const webpack = require('webpack');
const extractSass = new ExtractTextPlugin({

Answer 1

我想重申一下Jornve意识到了，因为我也花了一段时间才弄明白这一点。 query-string包在 IE 中不起作用。正如文档中所述，

This module targets Node.js 6 or later and the latest version of Chrome, Firefox, and Safari. If you want support for older browsers, or, if your project is using create-react-app, use version 5: npm install query-string@5.

删除依赖项并编写我自己的函数实现解决了我的问题。我没有尝试使用该软件包的第 5 版，但也许这也能解决问题。
