npm install PATH for postinstall scripts on Jenkins - jenkins

Question

My JS project uses a NPM package called commitizen:
https://github.com/commitizen/cz-cli
commitizen is added to my devDependencies in package.json file.
commitizen uses internally a package called opencollective as you can see here: https://github.com/commitizen/cz-cli/blob/master/package.json
commitizen on postinstall hook is calling opencollective postinstall which is supposed to run opencollective package binary.
Locally I've no problems running the postinstall hook, however, when I build my project on my Jenkins CI box I get this error when it runs the postinstall hook of commitizen package
sh: 1: opencollective: not found

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
I tried to add node_modules/opencollective/dist/bin dir to the PATH but with no luck, I think because the opencollective alias is defined in opencollective package.json
Any idea about how to be able to run opencollective command without installing globally opencollective package?
Thank you!
