Angular/cli 安装错误
Angular/cli installation Error
我在尝试使用 npm 安装@angular cli 时遇到了巨大的错误
我在公司网络中工作。这在我在家创建 cli 项目时有效。

好像你在代理服务器后面，所以 npm 无法访问 github
您需要通过公司代理配置 npm，例如：
npm config set proxy http://company-proxy-here:port
npm config set https-proxy http://company-proxy-here:port
查看更多详情Using npm behind corporate proxy .pac
转到 Windows 的用户目录并转到有您名字的目录
您会找到一个名为 .npmrc
的文件
使用任何文本编辑器对其进行编辑。
添加以下行：
注册表=http://registry.npmjs.org/
proxy=http:// username:password@ip:port
http-proxy=http:// username:password@ip:port
https-proxy=http:// username:password@ip:port
strict-ssl=false
