Npm编译器：无法读取未定义的属性'startsWith'

我没有设置https://github.com/vuejs/vue-cli Vue CLI与webpack template，它工作正常。但是，当我改变模板文件中的东西，它会抛出错误。Npm编译器：无法读取未定义的属性'startsWith'

请帮助在以下问题上，

问题是没有关系的，似乎引起由webpack-dev-server的依赖。 https://github.com/webpack/enhanced-resolve/issues/102 – Garth

太好了，谢谢。它解决了我的问题 – Hari

我能够在v3.4.0重现，但不是在V3.4.1（这后来被释放约5小时）。

要确认你在v3.4.0：

npm list enhanced-resolve

请更新增强的决心V3.4.1：到VUE-CLI

npm i enhanced-resolve
