import django fails, what should I look at?

[Dan Bikle]

Hello World,

I'm curious about working with the dev-version of Django.

I want to get skilled at using Django, Python 2.7.8, and virtualenv together.

I see this page:

https://github.com/django/django/blob/master/INSTALL

I installed python and then virtualenv:

d...@cen113.dan ~ $ which python
/home/dan/venv1/bin/python
d...@cen113.dan ~ $
d...@cen113.dan ~ $
d...@cen113.dan ~ $ /home/dan/venv1/bin/python
/home/dan/venv1/bin/python
Python 2.7.8 (default, Jul 15 2014, 03:37:39)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> quit()
d...@cen113.dan ~ $
d...@cen113.dan ~ $
d...@cen113.dan ~ $

The above INSTALL page says this:

AS AN ALTERNATIVE, you can just copy the entire "django" directory to Python's
site-packages directory

I did this:

d...@cen113.dan ~ $
d...@cen113.dan ~ $
d...@cen113.dan ~ $ cd /home/dan/venv1/lib/python2.7/site-packages
d...@cen113.dan ~/venv1/lib/python2.7/site-packages $
d...@cen113.dan ~/venv1/lib/python2.7/site-packages $
d...@cen113.dan ~/venv1/lib/python2.7/site-packages $

git clone https://github.com/django/django.git

d...@cen113.dan ~ $
d...@cen113.dan ~ $ ls -la ~/venv1/lib/python2.7/site-packages/django/
total 112

At this point I have done what the INSTALL page says I can do.

I tried this:

d...@cen113.dan ~ $
d...@cen113.dan ~ $ which python
which python
/home/dan/venv1/bin/python
d...@cen113.dan ~ $
d...@cen113.dan ~ $
d...@cen113.dan ~ $ python
python

>>> import django
import django
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named django
>>>
>>>

Since I'm using virtualenv and the latest dev-version of Django together,
I must have a loose connection somewhere in my setup.


I have some questions:

q1: Is this statement true:
"
AS AN ALTERNATIVE, you can just copy the entire "django" directory to Python's
site-packages directory
"
??

q2: If import django failed for you how would you debug it?

q3: If I import a module and python cannot see it, do I need to be looking at any env variables?

You should use pip to install django.

This is how I go about it, from a fresh install.

mkdir ~/virtual
mkdir ~/projects
pip install virtualenv # unnecessary in python 3.3+
pip install virtualenvwrapper # use this. it will make your life much simpler
echo "export WORKON_HOME=$HOME/virtual" >> ~/.bashrc
echo "export PROJECT_HOME=$HOME/projects" >> ~/.bashrc
echo "source /usr/local/bin/virtualenvwrapper.sh" >> ~/.bashrc
source ~/.bashrc

After that, create your first virtualenv using mkvirtualenv foo, activate it using workon foo, and deactivate it with deactivate.

Install packages using by issuing pip install commands, so if you want django, you can use pip install django for the latest release or pip install -e git#https://github.com/django/django.git for the latest development version.

You might want to check the docs for virtualenv, virtualenvwrapper and pip. You may also benefit from using yolk (python package) to check what you already have installed in each virtualenv..

Best of luck!

Cheers,

For the record, the right command is pip install -e git+https://github.com/django/django.git#egg=django
