pendulum-3.0.0 Dependency

[flexyboooy]

While updating my flexget pyenv today I got this error:

Python 3.9.2
pip 23.3.2
flexget 3.10.7
Latest release: 3.11.0

Is this to be expected? Do we need to install Rust/Cargo now?

[gazpachoking]

Hmm, there should be precompiled wheels available. What platform are you on?

[gazpachoking]

you could also try to set the environment variable PENDULUM_EXTENSIONS=0 before building. Either way, report back your platform. If this is a common issue I'd like to make installation go more smoothly somehow.

[flexyboooy]

I tried again while setting PENDULUM_EXTENSIONS=0 before updating but got the same error.

This is on a Raspbian GNU/Linux 11.8 (bullseye) on ARMv7 (armv7l).

[gazpachoking]

I built pendulum 3.0 without the rust extensions. Try to grab this version, remove the .zip extension, then in your virtualenv run pip install path/to/downloaded/pendulum-3.0.0-py3-none-any.whl
pendulum-3.0.0-py3-none-any.whl.zip (EDIT: I put a broken build up at first, this is now edited to be the proper one.)

This isn't a permanent solution, but might work before we figure a better way.

Here's the pendulum ticket for this issue. sdispater/pendulum#784

[flexyboooy]

I tried that and it let me upgrade to flexget v3.11.2 but unfortunately then flexget failed to start.

I am going back to a fresh install of flexget==3.10.7 for now and wait it out.

Thank you!

Oops, sorry about that, I made a broken one at first and turns out I uploaded that accidentally. You could run pip uninstall pendulum in your virtualenv, then try again with the same procedure with this one.
pendulum-3.0.0-py3-none-any.whl.zip

[gazpachoking]

Can everyone having this issue please post what platform you are on here? (what processor and OS) Is everybody with this issue on a 32 bit OS?

I'm experiencing the same or similar problem using Raspberry Pi OS () / 64 bit (Linux raspberryPi 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr 3 17:24:16 BST 2023 aarch64 / Raspbian GNU/Linux 11 (bullseye)).

After setting PENDULUM_EXTENSIONS=0, "pip install --upgrade flexget" results in:

I also downgrade to 3.10.7 for the moment.

Big thanks for your great work and support!

Ah, this one did it, I was able to upgrade and start Flexget: 3.11.2.

Again, thank you!

[SpaceRat42]

Just wantet to add, that my problem might be related to the mssion virtal environment. On a second Raspberry Pi (Raspberry Pi Bookworm / 64 bit), flexgte is installed in an virtual environment I was able to update to 3.11.3 without problems.

Building of Pendulum 3.0.0 failing on venv:
Debian 8.11 armv7l (32bits)* - Kernel 3.2.68
Python 3.11.5
rustc 1.73.0
cargo 1.73.0

Workaround from #3905 (comment) worked. Thanks for that.

(*) Also seeing the PYO3_ENVIRONMENT_SIGNATURE="cpython-3.8-64bit" described in sdispater/pendulum#784 (comment)

[abugher]

Processor: armv7l (ARMv7 Processor rev 3)
OS: Debian 12, bookworm (Armbian)
cargo: 0.66.0 (OS package)
rustc: 1.63.0 (OS package)
python: 3.11.2 (OS package)

The problem I observed matched the general description: Installing or updating flexget depends on pendulum, causing an attempt to build, which fails. The pre-built wheels file worked around the problem for me as well. (Thank you.)

The specific error looks different. I don't see mention of variable type definitions or bit widths, but I do see noise about unstable features.

$ virtualenv flexget
$ flexget/bin/pip3 install flexget
