Hello Thomas,
thanks for the suggestion.
Out developers would like to use different versions with pkg_resources
switched from code, not from virtualenv.
I've modified the easy_install.pth but adding both version lead me to
VersionConflict error.
The solution was to remove all pylucene line from easy_install.pth.
Now pkg_resources.require("lucene==4.9.0") and
pkg_resources.require("lucene==4.10.1") runs smooth.
Can you provide me a lucene command to check the version of the loaded
lucene?
Many thanks,
Csaba

Hi Caba,
you probably have both ‚installed‘ - i.e. both versions are copied into your
global python’s site-packages directory, but only one is enabled by the
installer (pip or easy-install). The ‚active‘ packages are added to the python
sys.path - this is typically done in a file ‚easy-install.pth‘ in the
site-packages directory - e.g.
/Library/Python/2.7/site-packages/easy-install.pth
You may manually edit the file if you want to switch between different
versions. Alternatively (and recommended) you should give virtualenv a try -
this allows you to separate different python libraries from you global python
installation:
http://virtualenv.readthedocs.org/en/latest/
That way you can for example … (assume I’ve created a virtualenv called
‚pylucene48‘ before and installed PyLucene 4.8.x into this env.)
$ workon pylucene48
(pylucene48)$ python
Python 2.7.5 (default, Mar 9 2014, 22:15:05)
Type "help", "copyright", "credits" or "license" for more information.
>>> import lucene
>>> lucene.VERSION
'4.8.0'
The 'trick' of virtualenv is to create a local 'site-package' scope:
>>> import sys
>>> sys.path
['',
'/Users/koch/.virtualenvs/pylucene48/lib/python2.7/site-packages/pip-1.2.1-py2.7.egg',
'/Users/koch/.virtualenvs/pylucene48/lib/python2.7/site-packages/JCC-2.19-py2.7-macosx-10.9-intel.egg',
'/Users/koch/.virtualenvs/pylucene48/lib/python2.7/site-packages/lucene-4.8.0-py2.7-macosx-10.9-intel.egg',
'/Users/koch/.virtualenvs/pylucene48/lib/python27.zip',
'/Users/koch/.virtualenvs/pylucene48/lib/python2.7',
...
'/Users/koch/.virtualenvs/pylucene48/lib/python2.7/site-packages']
You can easily create new environments:
$ mkvirtualenv pylucene49
(pylucene49) $ pip install …
Hope this helps,
Thomas
