Description

When running a generator from a makefile target, flatpak-pip-generator cannot finish find the requirements-parser that it project virtual environment has installed:

 $ make
( \
	source ./builder-env/bin/activate && \
	pip3 install requirements-parser pipdeptree \
)
Requirement already satisfied: requirements-parser in ./builder-env/lib/python3.12/site-packages (0.9.0)
Requirement already satisfied: pipdeptree in ./builder-env/lib/python3.12/site-packages (2.21.0)
Requirement already satisfied: types-setuptools>=69.1.0 in ./builder-env/lib/python3.12/site-packages (from requirements-parser) (70.0.0.20240523)

( \
	cd /home/jreynolds/git; \
	if [ ! -d flatpak-builder-tools ]; then \
    	git clone https://github.com/flatpak/flatpak-builder-tools/; \
	fi \
)
( \
	source ./builder-env/bin/activate && \
	./builder-env/bin/python3 /home/jreynolds/git/flatpak-builder-tools/pip/flatpak-pip-generator \
		--requirements-file requirements.txt \
		--build-only -o requirements \
)
Requirements modules is not installed. Run "pip install requirements-parser"
make: *** [Makefile:34: requirements] Error 1

This is the same error I get when executing the command from bash, not in make.

Got this Requirements modules is not installed. Run "pip install requirements-parser" too. In Python interpreter got:

>>> import requirements
...
ModuleNotFoundError: No module named 'pkg_resources'
>>>

Running

pip3 install setuptools

fixed error.
