Any way of installing Spyder IDE on Manjaro (without Anaconda)?

[Shirshendu]

The Spyder IDE in the repos installs without errors but then does not run (gives errors regarding PySide and others). The installation via pip is also the same. Can Spyder not be installed in Manjaro without installing Anaconda??
Terminal output when running spyder (installed via pip) -

$ spyder
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

@Shirshendu

gives errors regarding PySide and others

Can you share the errors it gives? Ideally the full output.

The OS (via pamac )successfully install Spyder but it cannot start

Added that in the original post.

Looks like this is a know issue since May 2021
https://bugs.archlinux.org/task/70689?project=5&string=spyder
https://bbs.archlinux.org/viewtopic.php?id=268482

In the other hand, for the pip issue, someone have the same issue as the original author has in Manjaro since August 2020.

Spyder requesting PySide but unable to install the module.

With the stable update of 2021-11-19, spyder installed from the official repos works (for now, at least).
