Npm package installed but still goes on error.

When installing a package,
Is wix installing both “Dependencies” and “DevDependencies”??

if I compare with a similar Git HUB Project that works on WIX:
(This one works )

https://github .com/soldair/node-qrcode/blob/master/package.json

they put their “canvas” requirement in the “DevDependencies” block.

In the package I’d like to use:
https://github .com/ushelp/EasyQRCodeJS-NodeJS/blob/master/package.json

it is in “dependencies” .

Still stuck…
