Re: [Distutils] Limitations of setup_requires

[Joshua Boverhof]

I have a package specified in both "setup_requires" and "install_requires", the package is downloaded and used during setup but it is never installed in site-packages like the other entry. This is happening on both my Mac and a Linux box.

Here is what I'm doing:

          install_requires=[
              "ZSI >= 1.2.0rc2", "4Suite-XML >= 1.0rc4",
          ],

          setup_requires=[
              "ZSI >= 1.2.0rc2",
          ],

ssh1:%python setup.py install




%rm ZSI-2.0_rc2-py2.5.egg


          install_requires=[
              "ZSI >= 1.2.0rc2", "4Suite-XML >= 1.0rc4",
          ],

          setup_requires=[
          ],


[EMAIL PROTECTED](341)-ssh1:%rm ZSI-2.0_rc2-py2.5.egg


It now installs.

Reading http://www.python.org/pypi/ZSI/2.0-rc2
Best match: ZSI 2.0-rc2

This fails for me with setuptools-0.6c3, python2.5, but works with w/ python2.4 Now if I remove it from "setup_requires" and remove the egg (otherwise it does nothing): [EMAIL PROTECTED](342)-ssh1:%rm -rf pyGridWare.egg-info/[EMAIL PROTECTED] (343)-ssh1:%python setup.py install --force Downloading http://cheeseshop.python.org/packages/source/Z/ZSI/ ZSI-2.0-rc2.tar.gz#md5=25b3ab7a3ff8285d51c35c223359c060

Has anyone else noticed this behavior?

Yes it is since I'm "generating" code when I do
"make_generated_packages".

Okay, then before you call setup() in your setup script, create an instance of setuptools.dist.Distribution() that has setup_requires set, but doesn't include any packages; and don't do anything besides create it. Then, run your package generation, and finally run setup(). You do not need a custom Distribution subclass, as far as I can tell. The only disadvantage to doing it this way is that if somebody does "setup.py --help", your package is still going to do dependency downloads and code generation. But then, that also happens the way you're doing it now.
