XS Advanced Try reinstalling `node-fibers` error

[Former Member]

Hello

I got error when I push my first XS app.

I took the app from Github (myapp1) then I added Node Modules then I pushed it.

Here my error logs:

Can you please help with this ?

I don't know how can I fix it.

Hi there, I got the same error after update my XSA (to 1.0.66).

Looks like the older sap-xsjs nodejs module have difficulties to compile his own fiber module dependency with the most recent nodejs version available on xsa nodejs build pack.

Try to set the nodejs engine compatibility on your app by setting the following inside package.json file (works for me):

"dependencies": {
   <your modules dependencies>...
},
  "engines": {
    "node": ">=4.4.6 <5"
  }

You could also try to replace your sap-xsjs nodejs lib with the new sap@xsjs latest version. It will probably works too (just remember to take off the nodejs-engine restriction of package.json in this case).
