          rchitect 0.3.40 has just released, it contains wheels for python 3.11.

Ubuntu 22.04 running on Termux on Samsung A52s with Android 13, aarch64, I'm getting:

pip 23.1.2 from /root/VirtualEnviron/lib/python3.11/site-packages/pip (python 3.11)
(VirtualEnviron) [root@localhost](mailto:root@localhost):~# python3 -m pip install -U rchitect --only-binary :all:
ERROR: Could not find a version that satisfies the requirement rchitect (from versions: none)
ERROR: No matching distribution found for architect

Should it be able to find the wheel?

I think the answer to my question is NO. There is no wheel for my environment. I edited the original post to describe it better. Please, could anybody confirm? Thanks!

As stated in Python Packaging User Guide » Tutorials » Installing Packages Source » Distributions vs Wheels section:

"If pip does not find a wheel to install, it will locally build a wheel and cache it for future installs, instead of rebuilding the source distribution in the future."

Thus, I conclude that what I'm seeing here is an issue when locally building a rchitect wheel.

I don't know if building a wheel is more demanding than any other possible alternative to install rchitect in my system. Any insight will be very welcome! Thanks in advance!

why do you need to build the wheel? it should be easy to install it from source.

I'm just trying to avoid screwing up things by following installation advice on the documentation. To the best of my current understanding, building a wheel implies a compilation. I guess what I'm getting is the same error. See below.

I also guess the key part of the error message is "is not accessible for the namespace "(default)", but I'm not able to understand that message and act accordingly. I can locate _cffi_backend.cpython-311.so and libpython3.11.so.1.0, but not able to understand the error message and correct the situation.

Any help is very welcome! Thanks!

I think that I'm failing to build from source or build the wheel for the same reason: my Python installation is in Termux's files structure, while Python packages required by the compilation sit on Ubuntu 22.04 LTS running on Termux:

(VirtualEnviron) root@localhost:~# file /data/data/com.termux/files/usr/lib/libpython3.11.so.1.0
/data/data/com.termux/files/usr/lib/libpython3.11.so.1.0:

I can build from source in mac OS X, and on a standalone Ubuntu 22.04 LTS installation. Thus, there is no issue affecting rchitect, but how I'm trying to use/build it. I will look for help at the concerned development site and insert references to this issue. Any insight and/or confirmation of my understanding of the issue is welcome! Thanks!
