CentOS 6.2上的cx_Oracle安装问题

Question

I feel bad posting yet another question on this, but all the others I've read through ended with a solution that doesn't necessarily apply or fix my issue.

I have Oracle running on CentOS 6.2. Database is up, sqlplus connects fine. I'm using Python 3.2 and Oracle 11.2.0.3

I found and installed the package cx_Oracle-5.1.1-11g-py32-1.x86_64.rpm without error.

[paws@linux ~]$ ls -al /usr/lib/python3.2/site-packages
total 360
drwxr-xr-x. 2 root root   4096 May  2 12:04 .
drwxr-xr-x. 3 root root   4096 Apr 13 09:31 ..
-rw-r--r--. 1 root root    898 Oct  8  2011 cx_Oracle-5.1.1-py3.2.egg-info
-rwxr-xr-x. 1 root root 353356 Oct  8  2011 cx_Oracle.cpython-32mu.so
[paws@linux ~]$ 

However when attempting to import cx_Oracle I still get an import error. I've checked the PYTHONPATH as shown below, and the appropriate directory is there:

[paws@linux ~]$ python
Python 3.2.2 (default, Apr 13 2012, 09:15:56) 
[GCC 4.4.6 20110731 (Red Hat 4.4.6-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import cx_Oracle
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named cx_Oracle
>>> import sys
>>> print (sys.path)
['', '/home/paws', '/usr/lib/python3.2/site-packages', '/usr/local/lib/python32.zip', '/usr/bin/Python-3.2.2/Lib', '/usr/bin/Python-3.2.2/Lib/plat-linux2', '/usr/bin/Python-3.2.2/build/lib.linux-x86_64-3.2', '/usr/local/lib/python3.2/site-packages']

Is there anything else I can check to resolve this? I've installed cx_Oracle many times on Windows without issues, but this is the first time on linux, so I must be missing something simple.

Any help much appreciated.

Just a thought. I wonder if its an issue with your version tagged files .

At the python prompt, what do you get when you enter:

>>>import sysconfig
>>>sysconfig.get_config_var('SO')

You should get: 'cpython-32mu.so'

If not, you could try creating a symlink to point to this.
