Support for Python 3.10

[jacksund]

Hello all :wave:

Are there any plans to add python 3.10 support to this feedstock?

When installing spyder to a clean environment with:

conda create -c conda-forge -n test python=3.10 spyder

There are currently incompatible packages:

Collecting package metadata (current_repodata.json): done
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

Just some info: Python310 is automatically added to all feedstocks by conda-forge over time through PRs. Unfortunately, this failed for this feedstock as can be seen on the status page: https://conda-forge.org/status/#python310 under Bot Error. (But not a maintainer here, just wanted to add that)

@BastianZim, thanks for noticing that! I was waiting for that PR.

@conda-forge/core, how can we proceed with the migration manually?

[beckermr]

If check the logs to see what the error is if you can. Usually a bot error is something to be fixed.

[BastianZim]

Fix in #125. @beckermr The bot retries automatically, right?

[beckermr]

Yes. It can take sometime to circle back to older PRs

[BastianZim]

Hmm the new error is now

Error: not solvable (bot CI job): master: ["TypeError('__init__(): incompatible constructor arguments. The following argument types are supported:\\n 1. libmambapy.bindings.Transaction(arg0: mamba::MSolver, arg1: libmambapy.bindings.MultiPackageCache, arg2: List[libmambapy.bindings.Repo])\\n\\nInvoked with: , ')"] 

But I haven't seen that one before.

@wolfv, any ideas about this problem?

[BastianZim]

Might be a bot problem: https://gitter.im/conda-forge/conda-forge.github.io?at=6205118e51bd8b580c980f49

Happens a couple of times: https://conda-forge.org/status/#python310

[ccordoba12]

So, what can be done to move forward with this?

[BastianZim]

Seems like we need to wait for an update: https://gitter.im/conda-forge/conda-forge.github.io?at=62069615ced11857f9a59531
