解决vue项目拉取后安装依赖报python问题

给项目安装依赖时报python问题，如下

Downloading binary from https://github.com/sass/node-sass/releases/download/v4.11.0/win32-x64-83_binding.node
Cannot download "https://github.com/sass/node-sass/releases/download/v4.11.0/win32-x64-83_binding.node": 

HTTP error 404 Not Found

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
