我使用universal-starter 作为主干。

当我运行npm start 时，我得到了错误：

我尝试了here提到的walkaround方式，让webpack回到2.1.0-beta.22版本

npm uninstall webpack --save-dev
npm install webpack@2.1.0-beta.22 --save-dev

但是，我仍然遇到了这个问题。

还有其他可能导致此问题的原因吗？谢谢

【问题讨论】：

可能是你的 webpack 也升级了 23.beta 请检查 webpack 版本
@CodeBuster 我试过npm uninstall webpack --save-dev，npm install webpack@2.1.0-beta.22 --save-dev。甚至是全球的npm install -g webpack@2.1.0-beta.22，但仍然是同样的问题......
我遇到了类似的问题，那是因为 webpack 版本，我猜这个错误是因为版本问题（可能是一些包或 npm）。

【解决方案1】：

对于大多数人来说，问题可能是因为您更新到最新的webpack@2.1.0-beta.23（有重大更改）而您尚未更新 webpack.config.ts。

所以你可以这样做

npm uninstall webpack --save-dev
npm install webpack@2.1.0-beta.22 --save-dev

但是，我的错误是我改变了

styles: [
  require('./app.component.scss')
],

到

styleUrls: ['./app.component.scss'],

但是我没有正确设置 webpack，所以当我改回来时，它现在又可以工作了。

所以我想只要 webpack.config.ts 中有错误，就会发生这个错误。它只是没有说清楚错误在哪里。
