Hi. I was having the same problem and was able to fix it by applying this patch to node_modules/promisify-node/utils/args.js :

< var args = func.toString().match(/functions.?(([^)]))/)[1];

var args = func.toString().match(/functions?.?(([^)]))/)[1];

You just need to add that extra "?" character after s .

Cheers.

Hello,
I got the same problem during my installation.
I upgrade promisify-node in package.json
"promisify-node": "^0.5.0",

I got a problem with sqlite3 as well, i upgrade it in package.json:
"sqlite3": "^4.0.0",

rm -rf node_modules
npm i

And all seems to work.

Can you try again? I released a major new version recently (0.6) which I think also fixed this issue. Assuming this is now fixed, if not please comment :)
