python3.10 bdist_wheel did not run successfully when install cffi

Question:

i installed Ubuntu 22.04 (fresh installation) an create an virtualenv with Python 3.10.

The installed packages are as follows:

libpython3.10:amd64
libpython3.10-dbg:amd64
libpython3.10-dev:amd64
libpython3.10-minimal:amd64
libpython3.10-stdlib:amd64
python3.10
python3.10-dbg
python3.10-dev
python3.10-minimal
python3.10-venv

When I try to install the application requirements file I see this error:

note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.

any ideas??

I have tried reinstalling the Python installation packages but the problem persists, I have read some publications and indicate that the problem may be caused because there are no headers related to the python dev package.

Answers:

Most probably cffi==1.14.0 is not compatible with Python 3.10. Try the latest version:

pip install cffi==1.15.1
