Cannot find module 'commitizen'

[travi]

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.

i notice that if i install commitizen locally, things work again, so it seems that git cz is not finding the globally installed version for some reason

[travi]

looks to me like the issue is the direct dependency on the commitizen package in order to use its config loader. This package only marks commitizen as a devDependency, so when commitizen is installed globally, but cz-conventional-changelog is installed locally, it isn't able to access commitizen.

i'll put up a PR to mark commitizen as a dependency instead of a devDependency. i could see this as a potential reason to split the config loader to a separate package, but that decision is totally in your hands.

I had a similar problem when updating an old package and in my case the problem was that in my package.json I had the following config:

  "config": {
    "commitizen": {
      "path": "./node_modules/cz-conventional-changelog"
    }
  }

I was getting the issue even when I'd updated to ^3.0.2, and found I had to update the config to:

  "config": {
    "commitizen": {
      "path": "cz-conventional-changelog"
    }
  }

This is actually what's documented in the setup instructions 😅 so I'm just putting this here in case it helps anyone.

@morphatic thanks for this. I got the message 'Could not resolve' after following the docs and installing -g and also setting up the repo to be Comitizen friendly.
I updated the package.json config as you suggested

"config": { "commitizen": { "path": "cz-conventional-changelog" } }
and it now works! - this was effecting cz-cli@4.3.0, cz-conventional-changelog@3.3.0
