google-crc32c C extension could not be imported

[msxdan]

Hi, I installed keepercommander using pipx and python 3.12 and I'm getting a warning about google-crc32c C extensión not being loaded.

/home/user/.local/share/pipx/venvs/keepercommander/lib/python3.12/site-packages/google_crc32c/__init__.py:29: RuntimeWarning: As the c extension couldn't be imported, `google-crc32c` is using a pure python implementation that is significantly slower. If possible, please configure a c build environment and compile the extension
  warnings.warn(_SLOW_CRC32C_WARNING, RuntimeWarning)

Steps to reproduce:

OS: Ubuntu 24.04 WSL Python: 3.12 Python env: pipx Command: pipx install keepercommander

Any idea how I could install the extension?

According to the PyPi page for the dependency in question ("google-crc32c"), only Python versions <= 11 are supported. That said, you can either 1) install the previous version of python instead (3.11 or earlier) or 2) compile the C extension referred to in your error message (this is what the PyPi page above suggests, but requires a dev setup of sorts)

It's probably much easier to do the former than the latter, and without much of a downside.

I installed python 3.11 and installed google-crc32c 1.5.0 but still showing the same warning

Could be something related to pipx, I'll try to install it without it

Even when installing keepercommander using python 3.11.9 without pipx shows the warning

Algo using python 3.9.5

The Commander does not use this library directly. It is a dependency of the aiortc package. This warning means that there is no native package build for your system. The list of all builds can be checked here https://pypi.org/project/google-crc32c/#files

There is no build for Python3.12 (cp311 means Python3.11) Ubuntu 24 WSL uses Python 3.12. It was suggested to install older versions of Python from add-apt-repository ppa:deadsnakes/ppa

Python3.11 from that repo works fine

(test) username@hostname:~$ python
Python 3.11.9 (main, Apr 27 2024, 21:16:11) [GCC 13.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import google_crc32c
>>>`

Google provides a valid build for Python3.12 eventually.

Anyway it is just a warning. It does not affect the Commander's core functionality.

The warning is a bit anoying because I use it with chezmoi but I can live with it.

Thank you both!

Here is how I mitigated that warning in my Fedora 40 (Python 3.12.3) installation:

1. Installed python3-google-crc32c using sudo dnf install python3-google-crc32c
2. Uninstalled the wheel google-crc32c that was previously installed by pip3 in my $HOME/.local/lib/python3.12

No warning anymore
