sockets - node-sass：无法建立隧道套接字

Question

当我尝试安装 node-sass 时出现此错误。我需要它来让工作吞下量角器。

C:\Windows\system32>cd C:\Program Files (x86)\Jenkins\workspace\testnew

C:\Program Files (x86)\Jenkins\workspace\testnew>npm install node-sass
npm WARN package.json testproject@0.0.0 No repository field.
npm WARN package.json 2@0.0.1 No repository field.
-
> node-sass@2.1.1 install C:\Program Files (x86)\Jenkins\workspace\testnew\node_
modules\node-sass
> node scripts/install.js

tunneling socket could not be established, cause=socket hang up

> node-sass@2.1.1 postinstall C:\Program Files (x86)\Jenkins\workspace\testnew\n
ode_modules\node-sass
> node scripts/build.js

有人知道如何解决这种错误吗？
