• 我正在使用Webpack和babel的最新版本。
• 当我尝试在IE11上运行代码时，出现指针函数的语法错误。
• 我检查了该块，并且它仅来自“ react-html-parser”。
• 该代码在chrome上正常工作，因为它支持指针功能。
• 我觉得babel不在node_modules上运行，因为我可以看到 指针函数将从src中删除，但不会从node_modules中删除。 （令人惊讶的是，material-ui和其他node_module似乎没有指针功能。）

以下是我的webpack配置：

      },{ //tried adding explicitly! doesn't work
        test: /\.(eot|jsx?)$/,// Transform all .js and .jsx files required somewhere with Babel
