[ome-users] [ome-devel] omero web problem with 4.4.10

[Aleksandra Tarkowska]

Dear Harri,

Thank you for reporting that. It looks like the following PR
https://github.com/openmicroscopy/openmicroscopy/pull/1928/files broke
compatibility. I am sorry about it.

If you wish to continue with Python 2.4 you can download older version of
that file from
https://raw.github.com/openmicroscopy/openmicroscopy/63f46817a17d979e3bda89
06089b55262ff022a5/components/tools/OmeroWeb/omeroweb/decorators.py and
replace it in OMERO_HOME/dist/lib/python/omeroweb/decorators.py

Still you might consider installing Python 2.6 as we are about to release
OMERO 5.0 that requires 2.6.

The simples way of maintaining various pythons on the same OS is Virtual
Environment. Please look at the following examples:

http://bda.ath.cx/blog/2009/04/08/installing-python-26-in-centos-5-or-rhel5
/
http://stackoverflow.com/questions/1534210/use-different-python-version-wit
h-virtualenv
http://toomuchdata.com/2012/06/25/how-to-install-python-2-7-3-on-centos-6-2
/

You will need to reinstall all your PYTHON packages within VirtualEnv but
that should't be an issue.

I hope that will help.

Kind regards
Ola
