Question

I have installed some python packages which I am able to access using IDLE and not through command shell window.

Here is the output from IDLE:

Python 2.7.2+ (default, Oct  4 2011, 20:03:08) 
[GCC 4.6.1] on linux2
Type "copyright", "credits" or "license()" for more information.
==== No Subprocess ====
>>> import whoosh

Here is the output from my terminal:

pradeep@ubuntu:~$ python
Python 2.7.2 (default, Nov 28 2011, 23:56:33) 
[GCC 4.6.1] on linux3
Type "help", "copyright", "credits" or "license" for more information.
>>> import whoosh
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named whoosh

How can I point the terminal python to IDLE python packages? Why is terminal showing ‘linux3’ where as IDLE showing ‘linux2’? Please help me with this path issue. thanks.

Update1:

Thanks all. Like most of you guessed, I have two different versions installed.

My Idle Path shows

['/home/pradeep', '/usr/bin', '/usr/local/lib/python2.7/dist-packages/Whoosh-2.3.0-py2.7.egg', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PIL', '/usr/lib/python2.7/dist-packages/gst-0.10', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/pymodules/python2.7', '/usr/lib/python2.7/dist-packages/ubuntu-sso-client', '/usr/lib/python2.7/dist-packages/ubuntuone-client', '/usr/lib/python2.7/dist-packages/ubuntuone-control-panel', '/usr/lib/python2.7/dist-packages/ubuntuone-couch', '/usr/lib/python2.7/dist-packages/ubuntuone-installer', '/usr/lib/python2.7/dist-packages/ubuntuone-storage-protocol']

My terminal path shows:

['', '/usr/local/lib/python27.zip', '/usr/local/lib/python2.7', '/usr/local/lib/python2.7/plat-linux3', '/usr/local/lib/python2.7/lib-tk', '/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/site-packages']

How do I remove the terminal version and install IDLE version in terminal? Thanks.

You’re running two different Python installs, one dated 10/4/2011 and the other dated 11/28/2011. The second one doesn’t have whoosh installed.

Your options are:

1. Look for the version that IDLE uses and run it from the command-line. To find it, turn on IDLE and run import sys; print sys.executable. That will show you the location of the version with the packages installed.

2. Or you can beef-up your command-line version by installing those same packages at the command-line (i.e. run python setup.py install for the various packages you want to load.
