Note:

Some dependencies may need to be manually downgraded or upgraded.

Alternatively, try to edit "install_requires" in "setup.py" and the requirements file ("requirements/conda.txt" in the source files or "requires.txt" in the installed files).

@willemw Thanks, spyder works beautifully after changing the following in /usr/lib/python3.9/site-packages/spyder-6.0.0.dev0-py3.9.egg-info/requires.txt:

pyqt5>5.10
pyqtwebengine>5.10
spyder-kernels>=2.0.5

@jmd: Yes, some dependencies are either too old or too new, according to Spyder.

Some manual action is required to at least start Spyder without errors. See pinned comment.

@willemw Alright with the newest build(5.1.1.r252.g0a86dcdc5-1), this is spyder's output:

Spyder seems to segfault for me when I start it up: Commands:

[1]    53718 abort (core dumped)  spyder

@willemw Unfortunately, when installing python-spyder-kernels-git, spyder also didn't work, either with the community package, nor spyder3-git. I am honestly confused why doesn't it.

@NiceMicro: python-spyder-kernels-git is too new or you decided not to use it?

(Usually, you can install either python-spyder-kernels or python-spyder-kernels-git for spyder or spyder3-git.)

@willemw yeah, that bug is what causes me to not use Spyder for 2 months now.

Luckily I saw in the bugreport a new comment, and figured that if I just build spyder-kernels based on the PKGBUILD for the community package, but with the newest version (replace version number and sha in the file and then makepkg -si), and then I install Spyder from the community repo, it works.

@davidovitch maybe this info might be useful for you.

Same here, neither the community package or in my pip-based virtual environments it was working at some point. What did work was creating a fresh new pip-based virtual environment and pip install spyder in there (no mini/anaconda). I didn't further dig into why it worked again, or what versions I had installed differently in the old vs the new virtual env.

@NiceMicro: for community/spyder there is a bug, still open: https://bugs.archlinux.org/task/70689. Consider installing Spyder the upstream recommended way (Anaconda)?
