python module import issues in command prompt
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.


Answer: 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.
