Packaging custom Python applications

[fgadaleta]

Is there a way/tutorial to package custom/local Python applications (that eventually depend on other modules usually installed from pip and requirements.txt file) ?

[indygreg]

Yes. PythonDistribution Starlark types have various methods to run pip, gather resources from virtualenvs, etc. See https://pyoxidizer.readthedocs.io/en/stable/config_api.html#pythondistribution-pip-install-args-extra-envs and the sections below it.

We could probably do with more examples outside of the low-level config API documentation.

Yes, I was following that Documentation and setup.py fails. I wonder what I am doing wrong. My config is

def make_exe(dist):
    python_config = PythonInterpreterConfig(
        run_module="black",
        sys_paths=["$ORIGIN/lib"],
    )

    return dist.to_python_executable(
        name="black",
        config=python_config,
        extension_module_filter='all',
        include_sources=True,
        include_resources=False,
        include_test=False,
    )

def make_install(dist, exe):
    files = FileManifest()
    files.add_python_resource(".", exe)
    files.add_python_resources("lib", dist.pip_install(["black==19.3b0"]))
    files.add_python_resources("lib", dist.setup_py_install(package_path="/home/frag/Documents/myapp-python"))
    return files

register_target("python_dist", make_python_dist)
register_target("exe", make_exe, depends=["python_dist"])
register_target("install", make_install, depends=["python_dist", "exe"], default=True)

resolve_targets()

and the error:

Of course myapp-python contains a setup.py that is installed successfully on a regular Python interpreter via python setup.py install
