    Uninstalling psutil-5.8.0:
      Successfully uninstalled psutil-5.8.0
  DEPRECATION: psutil is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

Do I have to install Visual Studio Build Tools? If yes, which workloads?

Hi @shivamshrey!

I also work on a Windows system, but I use WSL to develop fpdf2 in a Linux environment, so I never faced this kind of issue.

That being said, I found some intructions regarding psutil installation there: https://github.com/giampaolo/psutil/blob/master/INSTALL.rst#windows-build

I have just tested running pip install -r test/requirements.txt in a Windows environment and I had to install Windows binaries for SWIG but then everything got installed fine.
Regarding psutil, I got those log lines:

Collecting psutil==5.7.3

     ---------------------------------------- 239.4/239.4 kB 3.7 MB/s eta 0:00:00
Installing collected packages: psutil
Successfully installed psutil-5.7.3

The fact that you had a different behaviour on your computer (= the psutil package being compiled from sources) may be due to using an old version of pip (try pip install --upgrade pip) or not having installed the wheel package (try pip install wheel).

I hope this information will help you. Please keep me informed if you are still stuck, and good luck! 😊

[shivamshrey]

Thanks for your response @Lucas-C
I updated pip, installed wheel, and SWIG but got the same error as mentioned in the original post above.
I then tried installing psutil from sources and got the following:

$ pip install --no-binary :all: psutil
DEPRECATION: --no-binary currently disables reading from the cache of locally built wheels. In the future --no-binary will not influence the wheel cache. pip 23.1 will enforce this behaviour change. A possible replacement is to use the --no-cache-dir option. You can use the flag --use-feature=no-binary-enable-wheel-cache to test the upcoming behaviour. Discussion can be found at https://github.com/pypa/pip/issues/11453
Requirement already satisfied: psutil in c:\python\python39\lib\site-packages (5.8.0)

But after that, I just tried running the code example from readme and it worked. Does that mean that everything's in place?

On Ubuntu WSL, I got the following error initially:

But after that, I just tried running the code example from readme and it worked. Does that mean that everything's in place?

psutil is a transitive dependency used by memunit.
To check that everything is correctly installed, you can run pytest test/image/test_load_image.py that uses memunit, and verify that all the unit tests pass.

All the tests from test/image/test_load_image.py pass.
