Question

我已经按照Angular2教程并在package.json文件中包含相关行：

"@angular/http": "2.0.0-rc.4",

然而，出于某种原因，当Angular2服务器模块（井节点，基本上......）尝试加载依赖项时，我得到404。谁能告诉我加载这种依赖的正确方法？所有其他依赖项加载正常，但我需要http模块加载来自JSON文件的数据。

运行npm install时，我收到以下警告：

npm WARN cannot run in wd angular2-quickstart@1.0.0 typings install (wd=/root/OrderOfTheMouse2-0)

哪个可能与它有关？

此外，启动时的GET请求正在寻找以下路径，该路径似乎不存在：

[1] 16.08.07 19:52:31 404 GET /node_modules/angular2/bundles/http.dev.js

完整的package.json文件，按要求：

我的猜测是你需要先运行npm install - g typings命令。（警告信息也是如此）。然后尝试运行npm install。
