Can't build

[fusmau]

Hi! I tried to build your project using gulp electron:all but that's what I get:

C:\Users\fusmau\Desktop\iesm>gulp electron:all

I also tried to change the gulpfile.js in order to start the build for Windows only

gulp.task('electron:all', function () {
    return runSequence('clean', 'build', 'copy-package-json', 'electron:win');
});

but I got the same problem

I didn't make any change to the project, just ran the npm install and tried to build it.
What am I doing wrong?

Thanks,
