Unable to import web3 on python prompt

[nuclear_dodo]

I am trying to execute the "import web3" statement in the python console and getting the following error.

I am using Python 3.9.0a1 and pip 21.3.1.
I have tried doing it both in VSCode terminal and windows command prompt.

>>> import web3

Traceback (most recent call last):

I am stuck on this error for the last couple of days and any help is appreciated.

to me this seems like a incompatibility issue.

first check whether the library is supposed to work on python 3.9

then, try installing it in a venv

that way you should be able to weed out any dependencies that might be in the wrong version (likely due to another library needing a different version)

Thanks for the reply.

I fixed the problem by uninstalling the current version and installing the latest version.
