Describe the bug

I tried to build locust 2.13.0 on slackware-current but it failed to run with the following error message

locust

i have psutil 5.9.4, which is the latest version

Expected behavior

locust run normally

Actual behavior

locust failed to run

Steps to reproduce

build all dependencies of locust and locust 2.13.0

Environment

• OS: Slackware-Current
• Python version: 3.9.15
• Locust version: 2.13.0
• Locust command line that you ran: locust

Huh. That's strange. Can you try an older version of psutil just in case? Otherwise my guess is that your installation is corrupt somehow... Its not really a locust thing, as it happens directly on import of psutil.

[willysr]

i think it's because of this commit
giampaolo/psutil@25a2ab6

[willysr]

@cyberw which version of psutil did you use currently now?

[cyberw]

I have been using 5.9.1, but now updated to latest (5.9.4) now and both worked for me.

[willysr]

that's strange. I'm sure that my psutil installation is ok since i tested other code and it's working just fine

[cyberw]

very strange...
