ModuleNotFoundError: No module named 'psutil'

[electronhead]

Summary

• OS: macos 11.2.1 big sur
• Architecture: intel 64-bit
• Psutil version: Version: 5.8.0
• Python version: 3.9
• Type: { build }

Description

psutils works perfectly in my application on the mac as well as raspberry pi os, but when I invoke
python3 -m build I get the traceback below.

I then tried pip install --no-binary :all: psutil per the psutil documentation, still ending up with the stack trace below. xcode is installed BTW.

I've moved import statements around in the code with no effect.

I've also deleted venv, rebuilt it, installed all of the necessary packages, with the same traceback.

I've uninstalled and reinstalled psutil with pip and have deleted the two directories in site-packages and then pip-reinstalled. Same results.

Any tips would be greatly appreciated.

I resolved this issue as below: It seems, every time i was trying to upgrade psutil using "pip install psutil" it just showing "the requirement is satisfied and showing 5.7.2."

Use below steps to resolve this issue:

1. Go to the folder where Python is install and psutil is available e.g. "C:\Python\Lib\site-packages"
2. find all psutil related filesand rename them to something else e.g. Old__psutil Old_psutil-5.7.2.dist-info
3. Run "pip install psutil" from bash or command line
4. It updated for me to 5.8.0
   This resolved my issue.
