Another error caused by wrong access rights.

After installing Django 1.2.1 (wget  -> untar  -> install) on Ubuntu 10.04 64bit, attempt to start django-admin.py results in:

Traceback (most recent call last):

File "/usr/local/bin/django-admin.py", line 2, in <module>

from django.core import management

ImportError: No module named django.core

Testing within python shell results with similar error message:

Python 2.6.5 (r265:79063, Apr 16 2010, 13:09:56)

[GCC 4.4.3] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>> import django

Traceback (most recent call last):

File "<stdin>", line 1, in <module>

ImportError: No module named django

>>> quit()

A little bit of investigation:

$ python -c "from distutils.sysconfig import get_python_lib; print get_python_lib()"
/usr/lib/python2.6/dist-packages

Looking the sys.path:

Python 2.6.5 (r265:79063, Apr 16 2010, 13:09:56)

[GCC 4.4.3] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>> import sys

>>> print sys.path

['', '/usr/lib/python2.6/dist-packages/django', '/usr/local/lib/python2.6/dist-packages/django/bin', '/usr/local/lib/python2.6/dist-packages/django', '~/webapps', '/usr/lib/python2.6', '/usr/lib/python2.6/plat-linux2', '/usr/lib/python2.6/lib-tk', '/usr/lib/python2.6/lib-old', '/usr/lib/python2.6/lib-dynload', '/usr/lib/python2.6/dist-packages', '/usr/lib/python2.6/dist-packages/PIL', '/usr/lib/pymodules/python2.6']

And locating django-admin.py:

$ locate django-admin.py

~/install/sources/Django-1.2.1/build/lib.linux-i686-2.6/django/bin/django-admin.py

~/install/sources/Django-1.2.1/build/scripts-2.6/django-admin.py

~/install/sources/Django-1.2.1/django/bin/django-admin.py

/usr/local/bin/django-admin.py

/usr/local/lib/python2.6/dist-packages/django/bin/django-admin.py

/usr/local/lib/python2.6/dist-packages/django/bin/django-admin.pyc

Made me try to update the PYTHONPATH with this:

export PYTHONPATH="/usr/lib/python2.6/dist-packages/django:$PYTHONPATH"

and this:

export PYTHONPATH="/usr/local/lib/python2.6/dist-packages/django:$PYTHONPATH"

Do I need to say that “it didn’t work”? Again, it was usage rights… As you can see above, original django-admin.py is located in /usr/local/lib/python2.6/dist-packages/django/bin. While installing Nginx, I’ve already fixed the /usr/local folder and now it was turn for /usr/local/lib:

sudo chmod 711 /usr/local/lib

And, finally, Django works without troubles.
