npm只是不会安装节点sass

我在尝试使用离子时遇到了这个问题，它需要依赖于它的模板 . 然后当我尝试用npm自己安装node-sass时，问题仍然存在 . 这是在 Windows 10 Version 1703 ， nodejs 6.11.3 和 nodejs 8.4.0 都试用了，结果相同 . 和VPN，http代理尝试没有运气 . 基本上，它说：

无法下载“https://github.com/sass/node-sass/releases/download/v4.5.3/win32-x64-57_binding.node”

什么都没有摆弄，它说：

连接ECONNREFUSED 127.0.0.1:443

当使用npm set config proxy时，它表示如下：

隧道无法 Build

使用VPN时，它会永远等待：

node scripts / install.js

或输出相同的东西，好像什么都没有摆弄 .

报告错误时，您必须提供以下信息：

• NPM版本（npm -v）：5.3.0，节点最新（8.4.0），默认版本，节点6.11.3

• 节点版本（节点-v）：LTS（6.11.3）和LATEST（8.4.0）

• 节点进程（node -p process.versions）：

{http_parser：'2.7.0'，节点：'8.4.0'，v8：'6.0.286.52'，uv：'1.13.1'，zlib：'1.2.11'，ares：'1.10.1-DEV' ，modules：'57'，nghttp2：'1.22.0'，openssl：'1.0.2l'，icu：'59 .1'，unicode：'9.0'，cldr：'31 .0.1'，tz：'2017b'}

• 节点平台（node -p process.platform）：win32

• 节点体系结构（node -p process.arch）：x64

• node-sass版本（node -p "require('node-sass').info"）：错误：找不到模块'node-sass'

• npm node-sass版本（npm ls node-sass）：` - （空）

并且有输出

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

然后有人告诉我：

ECONNREFUSED很简单 - 您已将npm配置为与127.0.0.1（localhost）端口443处的代理通信，但代理似乎对此端口不起作用 . 请检查代理/ VPN软件配置 - 端口号必须匹配 .

但问题是我没有配置代理 . 我尝试了 npm config rm proxy 和 npm config delete proxy ，我甚至尝试使用它并设置代理然后将npm指向该代理，如上所述，没有任何效果 . 这里是powershell环境配置，以防万一：
