`command_runner` with `psutil` 5.5.1 (or lower)

[brendan-simon-indt]

I tried installing command_runner on via an embedded linux build system targeting a Debian 10 Buster distribution.
The build effectively does a pip install command-runner inside a ARM qemu system.

However the install fails due to the requirement for psutil>=5.6.0. pip tries to download this and build it, however I don't have the necessary build tools (i.e. gcc and friends) installed in the qemu system.

Debian 10 does have psutil 5.5.1 available as a package so I can install that easily.

Is there anyway to make command_runner work (install) with psutil 5.5.1 ??

What features of command_runner specifically need psutil > 5.6.0?

Interestingly command_runner installs ok for Python 2 (pip install command_runner), but not for Python 3 (pip3 install command_runner). I had to use psutil-5.7.2 from buster-backports to get it to install for Python 3.

# pip list | grep "runner\|psutil"
command-runner                1.4.0      
psutil                        5.5.1    

# pip3 list | grep "runner\|psutil"
command-runner     1.4.0  
psutil             5.7.2  

NOTE:

• psutil 5.7.2 is available from Debian Buster Backports repo, but only for Python 3.
• I could install the build tools (gcc, etc) but I didn't want them on my embedded filesystem (might take up too much space) - I might be able to remove those tools after the build?
• I might be able to build a wheel manually and locate that somewhere where I could install it.
• Might be time to finally upgrade legacy Python2 codebase to Python3 ;-)

The requirements seems to be introduced in commit 7ac85be9a1cb23475f957bc70a5331882ce689b9.

Actually psutil 5.6.0 was a requirement since I built command_runner when that was the actual version.
Having read the changelogs at https://github.com/giampaolo/psutil/blob/master/HISTORY.rst, I see no reason you could not use psutil 5.5.1.

Btw, really still on Python 2 ? Python 2 gives me so much work for retrocompat :(

Yes I know. I still have legacy code to support. Eventually I will be able to migrate it to Python 3, but not now unfortunately. But I need/want to run on both Python 2.7 and Python >= 3.7.

Would you be able to do another release will the psutil dependency lowered to 5.5 or 5.5.1?

[Orsiris de Jong]

Not really, I'm not making non battle tested releases.
Perhaps you could just raw download command_runner and use it without pip ?
Do you have to build distributables for other computers ?

[brendan-simon-indt]

I have migrated all my code to Python3 and am using psutil 5.7.2 from Debian Buster Backports (buster-backports).

I intend to update my embedded distro to a newer version (Debian 12 Bookworm) sometime in 2023, which will avoid the backports (for a while at least).

I will close this issue.

Worked around using psutil 5.7.2 from Debian Backports (python3-psutil/buster-backports)

Thanks for the feedback.
