\> [OK] compiled file is ready (myApp.jx)
it successfully created myApp.jx and myApp.jxp
But when I executed command
\> jx myApp.jx
It gives errors as:

exports.formatters.o = function(v) {

Answer 1

I dont think,the problem is with NPM, step by step compile each of the .js file, and introduce required NPM package one by one , you will get the solution.

Answer 2

Since it is not a JXcore issue (the app fails with node too), you might want to seek the problem related with js-bson: Failed to load c++ bson extension, using pure JS version.
For example I saw this answer: Failed to load c++ bson extension, and they say it could be fixed by reinstalling modules with npm install.
