Lerna throws a error when there is nothing to publish

Expected Behavior

Lerna should not throw an error but just log out that there’s nothing to publish and carry on.

Current Behavior

> @ publish /home/ubuntu/apis
> lerna publish --cd-version=patch --yes

Possible Solution

I’m not sure why this is throwing an error but I think a warning would be enough here.

Steps to Reproduce (for bugs)

1. Publish all your unpublished changes.
2. Make sure there are no changes when running lerna updated.
3. Run lerna publish.
4. Notice error.

Context

I’m trying to run in a monorepo and don’t wan’t to fail a step because of this.

If there’s a way to check if there’s something to publish or not I could also just do that but couldn’t find anything in the docs. Something like:

lerna there-are-updates && lerna publish
