windows - npm 不会安装 node sass

Question

我第一次遇到这个问题是在尝试使用 ionic 时，它需要依赖于它的模板。然后，当我尝试自己使用 npm 安装 node-sass 时，问题仍然存在。这是在 Windows 10 Version 1703 上，nodejs 6.11.3 和 nodejs 8.4.0 都试过了，结果一样。和 VPN，http 代理都试过了，但没有成功。基本上，它是说:

Cannot download "https://github.com/sass/node-sass/releases/download/v4.5.3/win32-x64-57_binding.node"

当什么都没有摆弄时，它说:

connect ECONNREFUSED 127.0.0.1:443

当使用 npm set config 代理时，它说的是这样的:

tunnel cannot be established

当使用 VPN 时，它永远等待在:

node scripts/install.js

或输出相同，就好像没有任何东西被摆弄一样。

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 (node -v):LTS(6.11.3) 和 LATEST(8.4.0)

• 节点进程 (node -p process.versions):

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

还有输出

      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:

Well ECONNREFUSED is easy - you have configured npm to talk to the proxy at 127.0.0.1 (localhost) port 443 but the proxy does not seem to be active for this port. Please check proxy/VPN software configuration - port numbers must match.

但问题是我没有配置代理。我尝试了 npm config rm proxy 和 npm config delete proxy，我什至尝试使用它并设置一个代理，然后像我上面描述的那样将 npm 指向该代理，没有任何效果。这里是 powershell 环境配置以防万一:

⚡ rick@DESKTOP-1NVA03E  ~  $reg = "HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings"

⚡ rick@DESKTOP-1NVA03E  ~  $settings = Get-ItemProperty -Path $reg

我刚遇到同样的问题。通过在 C:\Python27\中安装 Python v2.7 解决了这个问题。 (我之前只在 C:\Program Files\Python36\中安装了 Python 3.6)
