This is because of #4604, which assumes Node 7.6+. If you upgrade to Node 8, that should solve your issue.

@connec should we put some kind of if on the async-in-REPL code so that it only loads on Node 7.6+?

[coderofsalvation]

ok thx. Not sure, but wasn't there a package.json-attribute to force a node-version?

[coderofsalvation]

it seems there is: https://stackoverflow.com/questions/29349684/how-can-i-specify-the-required-node-js-version-in-packages-json

@coderofsalvation We already have { "engines" : { "node" : ">=7.6 } } in package.json. Unfortunately, npm (at least version 3) does not seem to give any kind of warning when installing, though.

Closing as this isn’t really a bug, but after #4679 the coffee command should work in Node 6 too.
