poetry 1.2.0b3 lock fails with no output

[vstrimaitis]

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: macOS Monterey 12.4
• Poetry version: 1.2.0b3
• Link of a Gist with the contents of your pyproject.toml file: click

Issue

I've discovered a case where the latest pre-release version of Poetry (1.2.0b3) fails to lock dependencies in some cases. Unfortunately, I haven't been able to track down why exactly this happens, but I do have a concrete example (linked above).

Steps to reproduce:

• Install Poetry 1.2.0b3 (I installed it with pipx install --suffix @1.2.0b3 'poetry==1.2.0b3' to distinguish from my other installations)
• Create a pyproject.toml with kfp = "1.8.12" and gsutil = "^5.6.0"
• Run poetry@1.2.0b3 lock

The output I get is:

$ poetry@1.2.0b3 lock
Updating dependencies
Resolving dependencies... (0.1s)



$

Running the same command with -vvv:

$ poetry@1.2.0b3 lock -vvv

The line 1: selecting gsutil (5.11) seems very weird to me because gsutil==5.11 is incompatible with kfp==1.8.12 because the first one depends on google-auth >=2.5.0 and the second one - on google-auth >=1.6.1,<2

With some other combinations of dependencies I also ran into a similar issue where there is no output from running poetry@1.2.0b3 lock, but poetry@1.2.0b3 lock -vvv reveals an OverrideNeeded exception, which sounds similar to #5791 (and also prints the same line with pandas and numpy). If needed, I can try to find a combination of dependencies that reveals this exact exception, but I don't have it right now.

If I try to do the same with Poetry version 1.2.0b2, everything works fine and resolves gsutil to version 5.6 because that's the latest version compatible with the other library (kfp).

introduced at #5770: which is not to say that fix was necessarily wrong... @radoering

[dimbleby]

Tweaking the #5770 fix so that it only kicks in if a direct-origin-dependency is involved seems to limit it sufficiently that it un-breaks this new example.

But I'm not sure whether this is actually sensible or it is just putting one dodgy fix on top of another
