Question

我一直在研究一个Angular2项目（Webpack + Karma）几个月，它基于这个启动器的稍微旧版本： https://github.com/preboot/angular2-webpack

在我在另一台计算机上检查我的项目之前，一切都运行良好。使用

安装依赖项之后

npm install

我试着运行我的测试。这是出现这个错误消息的地方，我无法解释....

Can not load "webpack"!
WebpackOptionsValidationError: Invalid configuration object.
Webpack has been initialised using a configuration object that does 
not match the API schema.

我的package.json中的任何内容都没有改变很长时间：

有没有人知道这里发生了什么？

Answer 1

Webpack 2.2.0或其依赖项似乎存在问题。如果您将"webpack": "^2.1.0-beta.25"替换为"webpack": "2.2.0-rc.3"，我将再次使用。 rc.4是它破坏的重点

Angula2 Karma无法加载“webpack”！
