无法启动Angular2-webpack-启动

Question

我在github上学习了以下教程：https://github.com/AngularClass/angular2-webpack-starter/

我安装了node+npm并运行了npm install。克隆git存储库，运行npm install，然后当我想运行npm start时，它会失败并显示错误消息。

这是调试日志

您的npm版本相对较旧，您应该更新到最新的npm 3.x。

Npm 3引入了很多变化，比如最大程度的扁平依赖树，支持具有奇怪名称的包，等等。

所有这些入门教程都使用最新的npm运行。不需要更新节点，4.3就可以了。尝试执行以下步骤，看看是否正常工作：

将npm升级到npm 3并删除node_modules

• run npm
