npm start：启动脚本失败＆＃39; ng serve＆＃39;

Question

  

只是为了澄清这一点：我对AngularJS 以及任何人都是全新的   网络技术。我是Web开发的初学者。

     

我试图安装它并且我必须承认，经过许多＆＃34; 未知按钮按下＆＃34;，我可能已经做了很大的混乱，或者也许不是。

我按照 AngularJS网站教程安装Angular，然后我只是想推送＆＃34;红色按钮＆＃34;：

npm start

但它提出错误说：

所以我在Google Globe周围搜索过，但一无所获。

另外，我不知道这是否相关，但在我的TypeScript代码中：

import { View, Component } from '@angular2/core';
[... Components Here ... ]

它会抛出错误：

Cannot find module '@angular2/core'

如果有人能够启发我，那会让我很开心！

Answer 1

如果您刚刚开始使用角度2，请按照角度网站上提及的步骤进行操作。

1从这里下载入门项目。把它保存到本地文件夹让我们说c：\ test \。 location = https://github.com/angular/quickstart.git quickstart这就是你需要为hellp world app做的所有事情。

2）转到命令提示符然后cd c：\ test。 3）如果没有安装，请输入节点js。 4）npm安装 5）npm start

这将显示你的第一个有角度的2 hello world app。

此网站最适合学习角度2。 https://angular.io/docs/ts/latest/guide/setup.html

Answer 2

它有点奇怪，但根文件夹应该像这个模式，my-app，tour-of-heroes一样命名。

今天早些时候我遇到了这个问题，错误地复制了我的应用程序，如下所示： sudo cp -rv my-app tourOfHeroes 然后在tourOfHeroes里面运行npm start 得到了那个错误

几个小时后决定这样做： sudo cp -rv my-app tour-of-heroes 然后在英雄之旅中开始运行 然后就像魔术一样，我又回到了商业
