但是，依赖关系似乎安装了 – 我在项目目录中运行’npm install’，它运行良好，没有任何错误，只是一些警告。它将依赖关系文件夹添加到名为node-modules的父文件夹中，我可以在Windows资源管理器中清楚地看到。 node-modules文件夹包含angular2，bootstrap，copy-webpack-plugin等的文件夹。

有谁知道为什么Visual Studio告诉我他们没有安装？我也尝试从Package Manager Console运行npm安装，并进行“右键单击” – >在这些文件夹上恢复软件包，在解决方案资源管理器中给我警告。

这是我的package.json文件：
