write EINVAL "Unhandled 'error' event" on Windows 10 with Node 7.1.0 #2577
Description
Hello all,
New to mocha here. I have npm install mocha --save-dev. I have a folder named test with an empty file messages.js. If I run mocha, I get the following error:
Mocha 3.1.2
events.js:160
throw er; // Unhandled 'error' event

Windows 10
Node v7.1.0
Any ideas what could be causing this?

Hmm... So, this is an error calling
process.stdout.write('', <callback>)orprocess.stderr.write('', <callback>). (Took me a moment to figure out the stack trace was from 2.5.3, but I found the code.) Are you piping or redirecting the output anywhere?DeividasK commentedon Nov 10, 2016
I'm not doing anything apart from the steps mentioned above - install mocha, create empty file, run mocha.
DeividasK commentedon Nov 10, 2016
I realized, that the output in OP was from mocha 2.5.3. I have updated the OP with output from mocha 3.1.2.

Have it error on Windows 10 with Node v7.1.0 (mocha 2.5.3/3.1.2)
But with node v.7.0.0 and older work nice!.

This error in others projects
react/react-native#10824
electron/electron#7919

I filed an issue in the Node.js repo: nodejs/node#9542
Please head over there in case you have any additional (and useful) information to share.
Thanks

Reverting to LTS node version 6.9.1 solves the issue.

Thanks everyone for being one step ahead on this!
