setting PYTHONPATH variable doesn't "stick"

Postby Alan H » Tue Jul 16, 2013 4:41 am

I'm installing ver. 4.4.8 on Cent OS 5. I've got Python 2.3 and 2.4 installed. Ice is ver 3.3 I've nicely downloaded all the Ice site packages and everything went just fine EXCEPT that it all installed in the Python 2.3 directories. ...not the 2.4 directory. Hmm.

Quenstion 1 a) When I go to configure omero ---

bin/omero config set omero.db.name 'omero'

All afternoon I got this message about how it can't find Ice. OK, so I looked over my PYTHONPATH and lo and behold it refers umpty-ump times to paths that include python 2.4, not 2.3 where all my site directories are. So I did this, just like it says in the CentOS installation guide:

export PYTHONPATH=$PYTHONPATH:/usr/lib64/python2.3/site-packages/Ice

and even PYTHONPATH=${PYTHONPATH}:/usr/lib64/python2.3/site-packages/Ice
just like it says to do in the nifty CentOS instructions guide I downloaded and it seems fine. When I go look ...

echo $PYTHONPATH

my export command hasn't appended the python 2.3 directories to the path. GRRRRR. Of course I still can't figure omero because it can't find ICE. I know stuff I write with the export command will go away after I log out, but it wasn't written AT ALL. What's wrong?

Question 1 b. In frustration, I finally edited my ~/.bash_profile ( as root) and put in

export PYTHONPATH=${PYTHONPATH}:/usr/lib64/python2.3/site-packages/Ice/

actually I did this for both root and "omerouser", and now it can find ICE, but is this going to work for all my various users when they log in with their own accounts via omero.insight etc?

Question 2

I've unzipped the OMERO.server-4.4.8-ice33-b256.zip file. I've renamed the directory that it created "OMERO". Ok, it's wonky, there's an OMERO directory inside the /etc/OMERO directory but it should still be fine. Now when I try to run

bin/omero config set omero.db.name 'omero'

it's telling me that it can't find '/OMERO/OMERO/etc/grid/config.xml'

...and in fact that file isn't there. Also, there is no omero_dist directory to be found. I'm sure I'm doing something dumb, like unzipping the Omero download, but not installing or something, but what is the dumb thing I'm doing?

Hi Alan,

Thanks for the post. The OMERO server has a minimum requirement of Python 2.4 on Linux systems. The system requirements for an OMERO server are detailed here:

OMERO.server system requirements

If you can set up your system so that it is using the Python 2.4 installation, and meeting the other requirements, and then run through the OMERO installation again you should be okay. If you still have problems after that please get back in touch.

Cheers,

Colin

Hi Alan,

A quick note to say that if you've not seen our OMERO Linux Installation Walkthrough, you may well find it useful.

Best,

Kenny

Well. There you go. Time to blitz the Python 2.3 install!

Thanks to both of you... Hey, the L inux walkthough is for Debian/Ubunu...this is Red Hat/CentOS. I actually did read that walkthrough before I started.

OK, I saw no way to uninstall Python 2.3, so I just deleted the directory

/usr/lib64/python2.3

This of course removed the /usr/lib64/python2.3/site-packages/Ice directory, too. Now I looked at the /usr/lib64/python2.4/site-packages directory, and there's no Ice directory there. GRRR....but *OK, fine....... So I tried reinstalling all the Ice packages. No go, yum reports that they're already installed...so I used yum to remove all the ICE packages, and then used yum and reinstalled them again. Everything went swimmingly...

... except that there's still no Ice directory in /usr/lib64/python2.4/site-packages

without that, $PYTHONPATH isn't going to find Ice. I don't get why installing the packages didn't register them with Python. OK, Now what?

Took me a while, like a full day, to figure this out....omero_dist .. the "dist" is the distribution code of that build or beta or whatever. Like

OMERO.server-4.4.8-ice33-b256 ---- the "dist" = "server-4.4.8-ice33-b256"

See, you have to talk to me like a 4th grader or I don't get it! :roll:

All the packages are for Python 2.3, they install into /usr/lib64/python2.3 ...which I know. Hmmm. OK, so how to find the packages for Python 2.4? That's todays goal.

I got the rpm's for Ice 3.4 from zeroc.com for Red Hat Enterprise...downloaded the tarball, expanded and tried installing the rpms. A few of them installed..

There is still no Ice directory in /usr/lib64/python2.4/site-packages/
I tried running omero config set omero.db.name 'omero'

and now $PYTHONPATH finds the packages elsewhere, not in /usr/lib64/python2.4/site-packages

All you need to do here is remove the ice 3.3 packages first (rpm -e), and then install the ice 3.4 packages once they are gone so that you don't run into the conflict.

With regard to the python directory, there's an ice-python rpm which, once installed, will provide the needed bits and you won't need to set PYTHONPATH at all, because it will be in the standard search path.
