Hi again,
I got the same error with zpasswd, so had to repeat the process with that
section of buildout.cfg, too... Thought I'd explain the specifics, while I
remember...

The buildout configuration that seemed to fix this, was to add 'recipe =
zc.recipe.egg:scripts' to my package's section, and
'allowed-eggs-from-site-packages = peak' to the `[buildout]` section.
I found the documentation on these options, unsurprisingly on the
zc.recipe.egg and z3c.recipe.scripts PyPi pages.
('allowed-eggs-from-site-packages = peak' is not what I thought it was
yesterday, so please ignore it).
I don't think I had edited the zpasswd section before yesterday, so it
should have been exactly as it was, when initially generated by
`grokproject`:
[zpasswd]
recipe = z3c.recipe.scripts
eggs =
my_package
zope.password
entry-points =
zpasswd=zope.password.zpasswd:main
I'm not entirely sure why zpasswd has to import every module in
my_package, but it seems to try. So the above configuration causes zpasswd
to fail, when a required package is installed into the user's
site-packages folder.
It's worth mentioning, if you're unfamiliar with the user's site-packages
folder, that it is supported by every Python build system I've tried:
distutils, distutils2, numpy.distutils and setuptools. The following
setup.py command, which works on all of these build systems, installs a
package into the user's site-packages folder:-
$ python setup.py install --user
With the documentation in front of my, I added these options to zpasswd,
but none of these add the user's site-packages folder to the search path:-
include-site-packages = true
exec-sitecustomize = true
relative-paths = true
extra-paths = ${buildout:directory}/eggs
interpreter = python-console
However, changing the recipe does:
recipe = zc.recipe.egg:script
So, my conclusion is that it's a feature / limitation / regression in
z3c.recipe.scripts. I only say regression, because on the
z3c.recipe.scripts PyPi page, I've just read:-
"The script recipe installs eggs into a buildout eggs directory, exactly
like zc.recipe.egg [...]."
Well, not exactly... This is one difference. I'll continue to use
zc.recipe.egg, as that works as desired in this situation, but it feels
like I'm downgrading, which is never fun...
Hope that clarifies things, anyway.
Kind regards,
Alex
