Question

我是angular2的新手，并尝试在ubuntu上设置angularjs2.0项目。我在根目录my angular2 app中安装了npm。但在npm start上，它会出错：

以下是npm-debug.log

中显示的错误

0 info it worked if it ends with ok

我在同一目录中也有package.json文件：

请告诉我如何解决此问题。感谢

您没有package.json文件以供npm使用。您需要创建一个包含所有依赖项的域。修复/添加package.json到您的根文件夹，你应该没问题。

这是一个简单的package.json：

{
  "name": "myapp",
  "version": "0.0.1",
  "dependencies": {},
  "devDependencies":{}
}

更新：我克隆了这个项目https://github.com/AngularClass/angular2-webpack-starter.git，并且能够安装并启动。该项目的当前版本更先进，就像一个魅力。你怎么试试？
