gulp build does not work on Ubuntu 18.04

Hello,
when I launch gulp build, I obtain this error:

$ gulp build
[07:00:14] Using gulpfile ~/desktop/gulpfile.js
/usr/lib/nodejs/gulp/bin/gulp.js:132
gulpInst.start.apply(gulpInst, toRun);
^

TypeError: Cannot read property 'apply' of undefined

Thank you for your help.

Try this next time:

Use npx to launch gulp. NPX will launch the gulp version specifically

npx gulp build
npx gulp run
...

I've switched to gulp 4.0 so check the globally installed version if gulp 4.0

On ubuntu 18.04 it's the 3.9.1.6 version, I understood I can no more use gulp to build your PopcornTime version until Ubuntu update the version.

I can still start PT with this command:
npm install
npm start
