Error arising from socket.io

[jat255]

Hello,

I cannot run markmon on Arch Linux using the latest node. After installing with npm, I get the following error when running markmon:

$ markmon                                                                                                                                                                                               express deprecated app.configure: Check app.get('env') in an if statement ../../usr/lib/node_modules/markmon/lib/Server.js:32:9

node --version   ->    v7.2.1
npm --version    ->    4.0.3

Installing v6.9.2 works as expected

Is the actual issue here Node 7 support? Broke for me when I upgraded Node on Mac OS.

Edit: fixed mine by downgrading, works in Node 6.7.0:
brew switch node 6.7.0
