module 'connect-livereload' not found on heroku

Question

I created a basic app via yo angular fullstack generator (default options, yes to everything except mogodb / mongoose integration). I try to deploy using (https://github.com/DaftMonk/generator-angular-fullstack#deploy):

yo angular-fullstack:deploy heroku

A quick local test via grunt serve does not show any errors. However the app fails to run on heroku.

Apparently this module: Error: Cannot find module 'connect-livereload' cannot be loaded. I found this Heroku Deploy Error: Cannot find module './errors/cast' on stackoverflow but I did not manage to solve the problem.

Hopefully someone could help me out.

Answer 1

as pointed out here: How can I get rid of Error: Cannot find module 'models' on Heroku

the environment variables for heroku have to be set
