I could install this squel npm with the XSA Client successfully, but somebody told me, I've to push it, otherwise it'll be only local on my computer. Is that true?
(I can't check it at this moment.)
So, now I tried to push (xs push) it, but I don't know how. And I'm not sure that is necessary.
As I said, I could execute this command - npm install squel@4.4.1 - successfully on the Client, but I'm still not able to build it.
