聚合物CLI安装在gecko驱动程序处挂起

Question

我正在尝试安装polymer-cli，但它挂在这里：

node_modules/polymer-cli/node_modules/wct-local
> node scripts/postinstall.js

selenium install:

我该如何解决这个问题？我已经尝试过通过NVM使用不同的Node版本，v4和v6。已尝试安装较旧的版本0.14与0.16。两者似乎都有相同的问题。已尝试下载geckodriver (https://github.com/mozilla/geckodriver/releases/download/v0.10.0/geckodriver-v0.10.0-macos.tar.gz)，在Chrome上没有问题。怎么了？

我的mac也有同样的问题。最后，这对我起作用了：

sudo npm cache clean
sudo npm install npm@latest -g
sudo npm install -g polymer-cli
