How to expose/install as executable an entrypoint from a virtualenv type RPM package

[John15321]

I created an RPM package using fpm like this:

fpm --verbose -s virtualenv -t rpm -n dupa_cli -v 1.0 -p dupa_cli-1.0.rpm -m "Your Name <your@email.com>"  /root/dupa-cli/

The package is created without a problem, the pyproject:

[tool.poetry]
name = "dupa-cli"
version = "0.1.0"
description = ""
authors = ["Your Name <you@example.com>"]
readme = "README.md"


[tool.poetry.scripts]
dupa-cli = 'dupa_cli.main:main' # this is the entry point as specified in Poetry documentation https://python-poetry.org/docs/pyproject/#scripts


[tool.poetry.dependencies]
python = "^3.11"
typer = {extras = ["all"], version = "^0.9.0"}


[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"

The package builds:

[root@7b13937f1d89 dupa-cli]# fpm --verbose -s virtualenv -t rpm -n dupa_cli -v 1.0 -p dupa_cli-1.0.rpm -m "Your Name <your@email.com>"  /root/dupa-cli/

After installation the package is visible and also present in /usr/share...:

[root@7b13937f1d89 dupa-cli]# rpm -i dupa_cli-1.0.rpm
[root@7b13937f1d89 dupa-cli]# rpm -qa | grep dupa
dupa_cli-1.0-1.aarch64

But although the python pyproject.toml specifies an entry point, the entrypoitn is nowhere to be seen:

[root@7b13937f1d89 dupa-cli]# rpm -i dupa_cli-1.0.rpm
[root@7b13937f1d89 dupa-cli]# rpm -qa | grep dupa

How can I/should I make it a normal executable from the perspective of the system?
