[npm install在我看来似乎不起作用

我下载了node.js，当我运行CLI命令npm install -g @angular/cli时出现以下错误：

npm ERR! code ENOTFOUND
npm ERR! errno ENOTFOUND
npm ERR! network request to /@angular%2fcli failed, reason: getaddrinfo ENOTFOUND proxy.example
npm ERR! network This is a problem related to network connectivity.
npm ERR! network In most cases you are behind a proxy or have bad network settings.

请任何帮助

如果有这样的错误...

npm ERR！网络“代理”配置设置正确

那么您必须正确设置代理

$ npm config set proxy http://XXX.XXX.XXX.XXX:XXXX

加号

$ npm config set https-proxy http://XXX.XXX.XXX.XXX:XXXX

您可以通过以下方式检查当前代理：

$ npm config get proxy

如果需要删除代理，请继续执行：（首先尝试以下操作）

$ npm config rm proxy   
$ npm config rm https-proxy
