我知道已经过了一年，但是我相信问题在于您的devtool配置:

I know it's over a year later, but I believe the issue was your devtool configuration:

webpackConfig.devtool = 'eval-source-map';

显然，IE11不喜欢webpack为它们插入的eval()代码.使用webpackConfig.devtool = 'none'(或替代值之一)应该可以解决该问题.

IE11 isn't a fan of the eval() code that gets inserted by webpack for those, apparently. Using webpackConfig.devtool = 'none' (or one of the alternative values) should fix it.
