webpack --progress Error: write EINVAL

Question

I'm on Windows 10 recently upgraded my node.js to version 7.1.0. I started to get the following error every time I ran the webpack command with --progress flag.

$ webpack --progress
Node Environment: development                                                                                                                                       events.js:160
      throw er; // Unhandled 'error' event
      ^

It works fine without the --progress flag and webpack --progress was working fine on node.js v6.xx Using webpack --progress with node v.7.1.0 on the same project but another windows 10 machine also works fine.

What does this error mean?

Answer 1

This is a problem of the version node, use the version 6.9 and success

I had the same problem, and i uninstall node7.1, reboot and install node6.9 and all ok

Answer 2

It seems there a bug at node js v7.1.0 nodejs/node#9542 . Update to the latest version v7.3.0 and everything will be ok.
