What's the aiohttp version and the rest of the context? I can only guess this is running the pure-python variant under Android but that's about it...

[bdraco]

It looks like we don't set a minimum Cython version

We should probably pin that in the build-system to what we use internally so we know we get the same result for manual builds.... the downside is it will install Cython to build even if extensions are disabled and won't use it (which is probably ok)

Assuming thats the problem, I opened #9876 for that, but I don't want to move it forward until we confirm

How did Cython appear in the system at all, despite it was brand new or outdated?

@FlutterGenerator how did you install aiohttp in your system?

termux mobile https://github.com/Netuzb/UMod Throws an error

[asvetlov]

Looks like @bdraco is right, old Cython version installed in the @FlutterGenerator box.
Installation on mobile is an edge case for aiohttp, we have no consensus on how to manage the problem once for everybody yet.

If you could install modern Cython it will fix the error.
Sorry, I never executed python on mobile and cannot provide comprehensive instructions.
