无法通过Angular 2中的npm安装依赖项 [英] Can't install dependencies via npm in Angular 2

问题描述

我已经从主站点(quickproject)下载了Angular 2，但是在安装其他库时遇到了很多问题.例如，当我尝试安装angular2-modal模块时，我得到:

I have downloaded Angular 2 from main site (quickproject) but I have a lot of problems with install additional libraries. When, for example I try to install angular2-modal module I get:

 npm install angular2-modal --save
angular-quickstart@1.0.0 C:\WebServ\httpd\quickstart
`-- angular2-modal@2.0.2

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 @angular/upgrade@2.2.4 requires a peer of @angular/platform-browser-dynamic@2.2.4 but none was installed.

由于这个fsevents，我无法安装任何东西.当我尝试做

I cannot install anything because of this fsevents I think. When I tried to do

npm update 

我收到了

推荐答案

从node_modules删除所有内容.从终端运行"npm install".然后尝试运行"npm start".确保您已安装最新版本的node&npm

Delete everything from node_modules. run "npm install" from terminal. then try to run "npm start". Make sure you have installed latest version of node & npm
