What version of node are you running?

[7feilee]

npm version 3.10.9
node version 7.0.0

[joassouza]

I guess you're having the same error reported in #3074 .
Can you downgrade the node version and try again?

[7feilee]

Thanks ,but i solve the problem by npm install xxx@xxx. Then problem raises where i run the xx.js.

[7feilee]

So i think it's not about dependencies.

[lpagliari]

@DannieFly as @joassouza mentioned, you're having the same error we're having when trying to update the dependencies to work with node v. 7 (see here). Using node 6.9 would probably work for you, but if you must use v. 7, then you'll have to wait for #3074 to be fixed.

Thanks
