在现有的angular2应用程序使用cliangular度通用安装

我正在按照以下链接https://universal.angular.io/quickstart/的指示，在现有的angular 2应用上实现通用cli时遇到一些问题

在第一个命令安装angular-universal

npm install body-parser angular2-universal preboot express --save 

我得到下面的错误

 npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules\chokidar\node_modules\fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.0.17: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"}) npm WARN enoent ENOENT: no such file or directory, open 'C:\test-app\node_modules\node_modules\package.json' npm WARN angular2-universal@2.1.0-rc.1 requires a peer of zone.js@~0.6.21 but none was installed. npm WARN angular2-universal-polyfills@2.1.0-rc.1 requires a peer of zone.js@~0.6.21 but none was installed. 

在执行第二个命令之后，我正面临下面列出的错误

我错过了什么？

没有什么，这些是警告，而不是错误。 你很可能安全地忽略这些。 在依赖关系之后安装依赖关系时会发生这种情况。

types的使用有点不赞成@types 。 而不是这些命令执行这些，并删除您的本地types文件夹：

 npm install --save-dev @types/node npm install --save-dev @types/express npm install --save-dev @types/body-parser npm install --save-dev @types/serve-static npm install --save-dev @types/express-serve-static-core npm install --save-dev @types/mime
