Hi, I have a dude, the singer-sdk library says it runs on python 3.10, but it depends on pipelinewise-singer-python = "1.2.0" and this library does not run on python 3.10 because this library depends on ciso8601 and this one does not run on python 3.10. I tried install singer-sdk in python 3.10.5

I'm using the sdk on 3.10.5 without issues on Linux. What OS are you using?

Oh, sorry, I use ubuntu on WSL, when I run the

poetry install

I get an error because ciso8601 doesn't support python 3.10, in the ciso8601 docs say that and singer-sdk library depends of ciso8601 .

Hey @michael_lan, what’s the error message you’re seeing?

ciso8601

does seem to be compatible with Python 3.10, but the maintainers of the package don’t publish any binary wheels so it has to built on every system and so the build tool-chain has to be installed in your system. In the case of linux that means python3-dev, etc. Also, we’re looking to remove that (transitive) dependency in the near term 🙂.

When I use python 3.9 with poetry all work, but with python 3.10 the error is:

EnvCommandError

Right, so it might depend on how you installed Python 3.10:

You may be able to work around this by setting

C_INCLUDE_PATH

to the location of the directory containing

Python.h

, which might be

/System/Library/Frameworks/Python.framework/Headers

. Depends on how you installed Python. It’ll be in a different location if you used Homebrew.

Regardless,

ciso8601

is definitely causing problems for some users.

Installing python3.10-dev solved the problem.
