node.js - Polymer CLI 安装在 gecko 驱动程序处挂起

Question

我正在尝试安装polymer-cli，但它卡在这里:

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

selenium install:

我该如何解决这个问题？我已经尝试通过 NVM 使用不同的 Node 版本 v4 和 v6。尝试安装旧版本 0.14 与 0.16。两者似乎都有同样的问题。尝试下载 geckodriver ( https://github.com/mozilla/geckodriver/releases/download/v0.10.0/geckodriver-v0.10.0-macos.tar.gz )，在 Chrome 上没有出现问题。怎么了？

我在 Mac 上也遇到了同样的问题。最后这对我有用:

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