$ pip install Plone
installed a lot of packages but then aborted with this error:
File "/Users/rob/.virtualenvs/plone/bin/../lib/python2.7/site.py", line 172, in addpackage
exec(line)
File "string>", line 1, in <module>
KeyError: 'z3c'
Plone
does not support installation via pip
, even though it can be found as a Python package with pip search Plone
.
I found this out by asking this question on the #plone
IRC channel.
Per @SteveM's comment, easy_install and setup_tools just can't deal with all the known-good-set issues for an application with as many dependencies as Plone. That's what buildout is good for.
