However, it is not related to packaging / distutils2 and will not be in the future, as there is no reason why this kind of feature would stand with packaging related code. -- Alexis ___ Distutils-SIG maillist - Distutils-SIG@python.org http://mail.python.org/mailman/listinfo/distutils-sig
Re: [Distutils] dependencies, pip and non-PyPI-hosted packages
Thanks. I have another question. Now that I'm using distribute, pip handles the requirements correctly, but if I install with: python setup.py install the dependencies are not installed. This is a bit perplexing. I am trying the scenario where the user has a plain Python installation with no pip, distribute or setuptools (hence installing the old fashioned way). My setup.py looks like this: # Begin of setup.py from distribute_setup import use_setuptools use_setuptools() from setuptools import setup, find_packages setup(..., install_requires=['project1'],...,dependency_links=['http://my.host.org/repository/'],...) # End of setup.py and I took care of including distribute_setup.py in MANIFEST.in, so it is part of the .tar.gz. When attempting to install, I get this $ sudo python setup.py install Downloading http://pypi.python.org/packages/source/d/distribute/distribute-0.6.15.tar.gz Extracting in /tmp/tmp4VDb5n Now working in /tmp/tmp4VDb5n/distribute-0.6.15 Building a Distribute egg in /home/eposse/Downloads/project2-0.1dev /home/eposse/Downloads/proyecto3-0.1dev/distribute-0.6.15-py2.6.egg /usr/lib/python2.6/distutils/dist.py:266: UserWarning: Unknown distribution option: 'install_requires' warnings.warn(msg) ... And the dependencies are ignored. I don't understand: I explicitly called use_setuptools in my setup, and as can be seen, distribute is automatically downloaded (albeit installed in a temporary directory), and imported setup from setuptools, but it looks like it is calling the plain distutils setup !? Why is it not calling the distribute/setuptools setup? Is there any way around this? Thanks PS: since 'requires' and 'provides' are not used in any tool, why are they in the official documentation?

This is quite disappointing, as a user may be unaware of dependencies automatically installed, and thus, the uninstall leaves behind something that was installed with the bundle. I imagine that the idea is that the user may install some other package that depends on 'project1' and pip takes the conservative approach (is that the case?) but I would have expected for pip or distribute or setuptools or distutils to keep some dependency reference counter. Does any of these tools have something like that? or is it going to be addressed in distutils2? No, there's no current Python packaging tool I know of that keeps a dependency reference counter and automatically uninstalls orphaned dependencies. The new standard installation format (defined in PEP 376 and implemented in distutils2) does record whether a package was installed by explicit user request or as a dependency; combined with checking dependencies of all other installed packages, this will make it possible for an uninstaller to implement automatic (or prompted) dependency uninstalls. 2) if install_requires is missing a dependency (project1), the package gets installed without that dependency, but if I add a dependency and the user attempts an install (project2) with the updated setup.py (listing the new dependency) pip will say that the package (project2) is already installed and won't attempt to install the dependencies. Is this correct? If so, is there a way to tell pip to install project2's dependencies? With a real package release, the setup.py metadata should never change without a version number change. In which case, if you specify the new version explicitly or use --upgrade, the previous version will be uninstalled and the new one installed in its place, with dependencies. (Actually, if you specify --upgrade and you already have the most recent version installed, it will still uninstall and reinstall it; but this is actually considered a bug.)

This is just how it is. python setup.py install installs the package in question. Installer tools like pip or easy_install handle dependencies. If you want dependencies handled automatically, your users will need to use pip or easy_install.

It extends distutils to do a number of different things (like install actual metadata, for instance), and it provides the metadata related to dependencies - but yes, it's easy_install or pip or zc.buildout (thanks Jim!) that actually makes use of the dependency info to automatically install things. Anyway, is automatic dependency installation going to be a standard feature of distutils2? Yes, d2 will come with a pysetup command similar to pip/easy_install that will handle dependencies.
