[Python] Python Package Installation Fails: 'Getting requirements to build wheel did not run...

In my python projects I create a list of required packages by pip freeze > requirements.txt it automatically list the packages with version. But after a while when I reinstall the package or trying to run other people project I have to install the dependencis with pip install -r requirements.txt. In this process some of the packages(For example, Pillow, numpy, etc) can't install the specific version that listed. By removing the version number it can install successfully.

In my current case, My project have requirement of pillow==10.3.0 but it shows the following error.

Collecting pillow==10.3.0 (from -r requirements.txt (line 6))

Then I tried to install the package with the same version manually and still fails. So, I installed pillow without version specification and it installed successfully.

(venv) D:\LMS>pip install pillow

I face this situation often, so I want to know why this happens or what to do in this situations.
