npm ERR！无效名称:"@ angular/core"遵循Angular 2快速入门时

本文介绍了npm ERR！无效名称:"@ angular/core"遵循Angular 2快速入门时的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试遵循 Angular 2快速入门，第一步是设置环境.我对npm并不完全陌生-我设法安装并试用了Ember，但是仅此而已.

I am trying to follow the Angular 2 Quick Start and one of the first steps is to setup the environment. I am not completely new to npm - I managed to install and try out Ember, but that's about it.

下面是我创建的package.json文件(从上面的链接复制). 当我运行npm install时，这就是我得到的. 快速入门说，我应该不看到任何npm错误！线.

Below is the package.json file I created (copied from the above link). When I run npm install here is what I get. The quick start says I should not see any npm ERR! lines.

npm WARN optional Skipping failed optional dependency /chokidar/fsevents: npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.0.12 npm WARN angular2-quickstart@1.0.0 No description npm WARN angular2-quickstart@1.0.0 No repository field. npm ERR!

Please include the following file with any support request: npm ERR! /home/john/development/angular/angular2-quickstart/npm-debug.log

其他尝试只会给我更多相同的体验:

additional tries just give me more of the same:

$ npm install npm ERR! Linux 3.13.0-85-generic npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "install" npm ERR! node v5.10.1 npm ERR! npm v3.8.3 npm ERR!

Please include the following file with any support request: npm ERR! /home/john/development/angular/angular2-quickstart/npm-debug.log

如果有帮助的话，这里是npm-debug.log的完整回溯:

Here is the full traceback from the npm-debug.log if that helps anyone:

由于我的评论回答了这个问题，因此我将以答复的形式提供给将来访问此页面的人.

Since my comment answered this question I will provide it in the form of an answer for the future people visiting this page.

经过一段时间的谷歌搜索后，我发现有两个页面存在相同的问题； 第1页和第2页.似乎某些版本的NPM中存在错误，因此只需升级到较新版本即可解决此问题:

After a little Googling I found two pages having the same problem; page 1 and page 2. It seems there's a bug in some versions of NPM so simply upgrading to a newer version should fix the problem:

sudo npm install -g npm

降级也可以解决此问题:

Downgrading could also fix the problem:

sudo npm install -g npm@<version here>

希望这会有所帮助
