In FME (2025.1.0.1, build 25609 at the time of writing), according to the official documentation, one can install Python packages using this command, e.g. on Windows:

C:\<install_dir>\FME> fme.exe python -m pip install <package_name>

and this works fine.

Indeed, it installs packages under:

C:\Users\<username>\Documents\FME\Plugins\Python\python<version>\

But how to properly uninstall a Python package in FME Form?

As one would naturally do in a standard Python environment, I naively attempted to run:

C:\<install_dir>\FME> fme.exe python -m pip uninstall <package_name>

But this fails in an obscure way:

C:\<install_dir>\FME> fme.exe python -m pip uninstall numpy
 
Python version 3.13 loaded successfully
 
Usage:
  C:\<install_dir>\FME\fmepython313\python.exe -m pip uninstall [options] <package> ...
  C:\<install_dir>\FME\fmepython313\python.exe -m pip uninstall [options] -r <requirements file> ...
 
no such option: --target
 
Error in running the Python command 'python %0'
Program Terminating
 
Translation FAILED.

The official documentation tells us how to install a Python package, but nothing about uninstalling.
