@vvjin Do you mind posting what version of Node you're using too? Thanks!

[vvjin]

E:\Users\vjin>node -v
v6.9.4
sorry for late reply, I was trying to figure out the problem.

[mewtaylor]

@vvjin thanks! I'm wondering if this is related to nodejs/node#7294 at all? It looks like it should've been fixed for v6.4 though...

I wonder if downgrading to LTS v4.x might be worth trying to see if that works, perhaps. Also, did you find anything else in your investigation by any chance?

Closing because of age. @vvjin Please reopen if you need more help!
