默认的webpack箭头功能IE11问题

问题描述

我对webpack和IE11有问题。我使用Babel进行编译，所有功能和内容都经过了webpackbootstrap函数的编译。如图所示，您可以看到打破IE11的箭头功能。我还创建了我自己的函数和JS，并对其进行了转译，因此仅webpack自己的js不进行转译。有没有人见过同样的问题？我已经在互联网上搜索了2天，并尝试了许多解决方案，但没有一个解决此问题。

您可以在图像中看到babel正确地编译了除默认webpack javascript之外的所有内容。

我对此感到迷茫，请帮助我！

谢谢。

解决方法

他在webpack v5中也遇到类似的问题。
