@realdennis does it works for you after the merge?

[realdennis]

Hey, I thought the root cause about Node v10 is the node_pcap(namespace error & depend old socketwatcher) but it fixed after merge 243

In this repo's(kickthemout) pull request, I just remove broken badge, update some dependencies and add Greenkeeper(but you need to open it).

Greenkeeper continuous check project's dependencies version and tell you CI result.
(You can merge it when build pass.) Like this.

By the way, I thought we need to write more test case to keep a robust CI not just check coding style.

[roccomuso]

Yeah, PRs are welcome. I had no time to write tests.

Btw right now the inquirer selection is stuck when i run it with node 8. Are you having the same issue?

[realdennis]

I don't have this issue in Node v8, but I found that Inquirer.js doesn't support version under Node v6, I am sorry to aware it too late.
