pfff no dice man, dependency error 😢

I've just tried this on my machine with a miniconda 3 for Python3.9 and conflicts creep up there too, making the solving go into slow mode, at least the memory is getting shored up at about 3GB now (still high); let me see if I can pin more stuff and try again

I had conflicts for Python>=3.6, but succeded for python >=3.7

Too bad it didn't work, I saw the build going past solving the esmvaltool environment without crashing, so I thought it worked, but sadly no.

@jvegasbsc can you commit please, we should be able to see the CI work though it, I can't get it to work no matter how many permutations I'd try on my machine and frankly am completely fed with trying 😆

[valeriupredoi]

what a turkey - conflict again! @jvegasbsc how did you get yours to work with pinning py at 3.7?

I also changed the version number to 2.2.0, try that

[jvegreg]

Also, the job will fail anyway because the tests are failing, but that should be fixed in other PR

[valeriupredoi]

yeah I just approved #2027 where that gets fixed, I just want to see the env being solved without Exit code 137 😁

[valeriupredoi]

@jvegasbsc you're a bloody genius! I just tested your solution with miniconda3 for Python39 (not the one labeled latest but a newer one made specifially for Python39) - and it works great 🙏 🍺

[jvegreg]

Finally!

[valeriupredoi]

@jvegasbsc 👏 🍺 and a small beer for me for identifying python as the troublemaker 😁

[valeriupredoi]

and the github actions are now all green and I have just got the news that my work contract has switched to permanent, good news all round 😁
