InstalledVersions::getPrettyVersion and InstalledVersions::getReference will be return null sometimes.

Could you please take a look ?

Thanks

Thank you for this PR, I was looking into this same issue because I was getting CI failures in getsentry/sentry-php#1170

While debugging there, I've found that the issue that caused that was the fact that I was asking for the version of a replaced package; so, returning a version there doesn't make sense.

What's your use case here then? I see that You're splitting ||, but that to me seems like you're working on a composer.json constraint, and not an exact version.

This seems the same stuff that I tried tackling in #16...

Sure, it is not an exact version.

It is a guess version.

Not a guess, it's a constraint, see the excellent explanation by Jordi (Composer creator) in #16 (comment).

I'm closing this in favor of #31, which is my proposed solution for this issue.

Ok
