Question

尝试使用npm安装@angular cli时，我遇到了巨大的错误我在公司网络工作。这在我在家创建cli项目时有效。

npm install -g @angular/cli
C:\Users\nitin.shekhar\AppData\Roaming\npm\ng -> C:\Users\nitin.shekhar\AppData\Roaming\npm\node_modules\@angular\cli\bin\ng

> node-sass@4.5.3 install C:\Users\nitin.shekhar\AppData\Roaming\npm\node_modules\@angular\cli\node_modules\node-sass
> node scripts/install.js

Downloading binary from https://github.com/sass/node-sass/releases/download/v4.5.3/win32-x64-48_binding.node
Cannot download "https://github.com/sass/node-sass/releases/download/v4.5.3/win32-x64-48_binding.node":

getaddrinfo EAI_AGAIN github.com:443

Hint: If github.com is not accessible in your location
      try setting a proxy via HTTP_PROXY, e.g.

      export HTTP_PROXY=http://example.com:1234

or configure npm proxy via

      npm config set proxy http://example.com:8080

Answer 1

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，如：

npm config set proxy http://company-proxy-here:port
npm config set https-proxy http://company-proxy-here:port

了解详情结帐Using npm behind corporate proxy .pac

Answer 2

转到Windows的用户目录，然后转到具有您名字的目录你会找到一个名为.npmrc

的文件

使用任何文本编辑器编辑它。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

严格的SSL =假
