# only the first time we install something 
pipx ensurepath
# close and open terminal again

# build, install and run to make sure it works
poetry build
poetry install
poetry run

# install localy with pipx
pipx install .

# now we're able to run it from anywhere
file-enlarger

in this case we invoke it as file-enlarger as the .toml declares it as such

[tool.poetry.scripts]
file-enlarger = "FileEnlarger:main"

Broken pipx?

Install your program with

# install
py -3.14 -m pip install --user .

# find installation to add to PATH
py -3.14 -m pip show fileenlarger

# add it to PATH; logout; restart console
file-enlarger

This will install it in your local /scripts or /Roaming folder. Remember to add it to your path. In this case it’s in

C:\Users\{user}\AppData\Local\Python\pythoncore-3.14-64\Scripts
C:\Users\{user}\AppData\Roaming\Python\Python314\site-packages
