Two days ago I updated virtualenv, transitioning it away from the
deprecated USE_PYDISTUTILS=easy_install to USE_PYDISTUTILS=yes as many
other ports have recently.
I thought nothing of it until the following report by Scott (cc'd):
http://lists.freebsd.org/pipermail/freebsd-python/2014-February/006592.html
The summary of that thread is:
a) Any python software that uses *console_scripts* needs the
pkg_resources module from setuptools at run time. This basically means
anything that installs a CLI utility.
b) Package-only users don't get setuptools installed when they install
the packages of the above ports, because =yes *doesnt* set a RUN_DEPENDS
on it.
This breaks console script invocation, with the following error:
Traceback (most recent call last):
File "/usr/local/bin/<script-name>", line 5, in <module>
from pkg_resources import load_entry_point
ImportError: No module named pkg_resources
Reproduction steps are:
1) Install port or package that uses console_scripts
2) If you installed the package, run the console script
3) If you installed the port
3.1) Run the console script
3.2) Remove py-setuptools
3.3) Run the console script again
Reproduced with: py-virtualenv (`virtualenv`), py-tox (`tox`) and
py-nose (`nosetests`)
We (python@) have now standardised on a consistent installation pattern
for all python software, whether pure-distutils or setuptools based, and
there are run-time requirements that are currently not being satisfied.
Attached is a patch moving RUN_DEPENDS+=setuptools from the
=easy_install only case, to the default case.
Patch review requested, other comments welcome.
