npm ERR！无效名称:"@ angular/core"遵循Angular 2快速入门时 [英] npm ERR! Invalid name: "@angular/core" when following the Angular 2 Quick Start
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:

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! argv "/usr/local/bin/node" "/usr/local/bin/npm" "install"

如果有帮助的话，这里是npm-debug.log的完整回溯:

推荐答案
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>
