after the latest release, i am seeing the following error when running git cz the same way i always have: Cannot find module 'commitizen'. I noticed the same problem when attempting to test this PR, but assumed at the time that I was simply pulling it down incorrectly during my attempt to test.

The simplest way to reproduce is probably to

• clone https://github.com/travi/javascript-scaffolder
• nvm install
• npm install -g commitizen (this is v4.0.2 for me currently)
• npm install
• make some code change and stage it for commit
• git cz
• see error

i'll try to find a chance to dig a bit to see if i can understand why this is happening for me and will add comments if i find anything, but wanted to at least get this opened in case the cause might be obvious to one of the core team.
