Answer 1

在执行命令npm install之前执行此cd myproject，然后执行以下操作：npm install

已解决。谢谢。

Answer 2

看起来您没有将package.json文件放在根目录中。如果你刚开始新的，你需要克隆这个回购。 https://github.com/angular/angular-phonecat

Answer 3

像Bilhan A说：你需要更改到克隆项目的文件夹。从你的问题我假设你是编程新手并且想要主要学习Angularjs。这不需要Node.js.如果您真的想学习Angular，我推荐像this one这样的教程，它们不需要node.js.当您了解它的工作原理时，请返回node.js并将它们组合起来。

Answer 4

name中的

package.json字段应与项目目录的名称相同。
