What is the expected behavior?

If I use Python, I can install Falcon using your APT source's python-pip.

pypy3 tries to call setxattr for a file in shutil.copymode. You can remove or comment the line 338 in $PREFIX/opt/pypy3/lib/pypy3.9/shutil.py.

Thank you.

I only fix the xattr issue for pypy(2) but not for pypy3.

I'm refactoring the build script these days, but have some other issues on pypy3. It's not easy to figure out why.

I'm Sorry. I forgot, the ones that passed the test just now were all directly pasted with my script, so the patch was directly applied to pypy3, which gave the illusion of passing the test. When testing the 4.x version kernel, it was not at the same time as the 5.x version kernel. As a result, when testing on my 4.x machine, I directly apt install -y pypy3;pypy3 -m ensurepip;pypy3 -m pip install falcon and got an error, mistakenly thinking that this fix was only for the 5.x kernel. I apologize to you again.
