Re: SyntaxError Creating New Project

[Kurtis Mullins]

Very weird. I ran the syntax and did not receive a syntax error. I just checked on the documentation and it does say Python 2.5 is required, which as you mentioned you have installed. 

Maybe double-check to make sure that you're executing this with the right Python executable? I'm running Python 2.7 if it makes a difference.

Here's a reference to the file that's giving you the error:

The "var = value if predicate else value" syntax was introduce in python
2.5, so it seems like the python interpreter that's being used to run
django-admin.py is older.

Try executing python and look at the version number. Check the shebang
in the 'django-admin.py' too.

As a workaround execute:

/path/to/python2.5 /path/to/django-admin.py startproject testproject

That error indicates the python executable processing django-admin.py is Python 2.4 level, not 2.5. With Python 2.5 I can import django at level 1.4.1:

kmt@lbox 20:04:15: ~/software/web
--> python
Python 2.5.2 (r252:60911, Jan 20 2010, 23:16:55)
[GCC 4.3.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import django
>>> quit()

If I try with Python 2.4 level, I get the error you are seeing:

kmt@lbox 20:04:45: ~/software/web
--> python2.4
Python 2.4.5 (#2, Jan 21 2010, 19:44:35)

You may have python 2.5 installed, but you seem to have 2.4 also, and 2.4 is what's getting used for the command you are running.

Thank you all for the tips. I was pretty sure I tried using the full path to the 2.5 install with the same error but I'll check again. I'll let you know what I find.

[Bestrafung]

I ran python and checked the version number. This is what I get:

[-bash-3.2 root@server1: ~] # python
Python 2.5 (r25:51908, Aug 20 2012, 11:55:47)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-52)] on linux2

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

When I run "import django" I get:

>>> import django
Traceback (most recent call last):

  File "<stdin>", line 1, in <module>
ImportError: No module named django


I assumed this was normal since the guide I'm following has all of the django setup in the user's home directory. Is this the problem? I will keep looking into it, the guide had me enter export PYTHONPATH='$PYTHONPATH:/home/username/sites/domain.com' in the user's .bash_profile, since I am logged in as root should I add that to the /root/.bash_profile?

[Bestrafung]

Ok, I think it's worked out now. I added the export line to the root .bash_profile and then changed the shebang in django-admin.py to "/opt/python2.5/bin python" and now everything seems to be working. If anyone is working on an older Red Hat/CentOS system and has to follow the guide I'm following I hope this helps them.

I imagine there's a typo there and no space, but a forward slash.

It's kind of weird that this fix works without problems. You should try
the following in your project directory:
/opt/python2.5/bin/python manage.py shell
On the shell you get then:
>>> from django.db import models
>>> print models.__file__

I'm quite interested what that shows since your installation seems to be
all over the place.

I've been extremely busy with other projects and just got back to this. It would appear you are correct about it not working correctly. I'm new to all of this and I'd have been lost long ago without that guide but it is severely lacking. Below is the result of the manage.py command.

[-bash-3.2 root@server1: /home/username/sites/domain.com/django/bin/testproject] # /opt/python2.5/bin/python manage.py

Traceback (most recent call last):

  File "manage.py", line 8, in <module>
    from django.core.management import execute_from_command_line
ImportError: No module named django.core.management

[Bestrafung]

I restarted from the beginning using the previously mentioned guide but also a very helpful post on the cpanel.net forums and there were some missed steps and minor misconfigurations. Everthing seems to be working on the webserver side but now have some strange permissions issues that'll go into another post. I hope this helps anyone else interested in setting up Django on a CentOS 5.x cPanel system.

Hi Daniel,

I am not spamming. just inform you that how to create django projects with initial steps.

I just replied for your 'SyntaxError Creating New Project' title.

I have prepared to make this answer for your questions. Is it related your query or not?
