I would like to find a way to install my own python package which depends on other custom python packages.

I followed this guide to create my own python packages: https://python-packaging.readthedocs.iao/en/latest/

For all packages, the minimal structure is:

myOwnPackage/myOwnPackage/__init__.pysetup.py

Now, I created a package which depends on other custom packages. Its structure is:

myOwnPackage/dependencies/packageApackageBmyOwnPackage/__init__.pysetup.py

My question is: How to easily install myOwnPackage and its custom dependencies with pip ?

For the above example, I would like to install myOwnPackage, packageA and packageB when I call pip like that: pip install myOwnPackage

I did not find a way to include dependency names in setup.py like I can do for official python packages like numpy, pyqt5 etc.

I find a way to solve my problem partially by using a requirements.txt with pip:

pip install -r requirements.txt myOwnPackage

and here is how I wrote the requirement file:

./dependencies/packageA
./dependencies/packageB

I works well, but not when I have recursive dependencies like that:

myOwnPackage/dependencies/packageA/dependencies/packageCpackageA/__init__.pysetup.pyrequirements.txtpackageBmyOwnPackage/__init__.pysetup.pyrequirements.txt

pip with the top-level requirements.txt will install myOwnPackage, packageA and packageB but it does not know that it has to install packageC which is a packageA dependency.

Any idea?

I almost solved my problem.

I need to build each dependency with the following command: python setup.py sdist in order to create a single package file (tar.gz)

Then, I can call them in the top-package setup.py:

...
dependency_links=["file:/local/path/myOwnPackage/dependencies/packageA/dist/packageA-0.1.tar.gz"],
install_requires=["packageA"],
...

Finaly, I run the following command to install myOwnPackage and its local dependencies:

pip install . --process-dependency-links

It installs all recursive dependencies if all repo are built and set correctly as describe above.

--process-dependency-links has been removed in last version of pip...
