I was using Django with Python 2.7 on Windows 7 and I installed XAMPP and used the PHPMyAdmin MySQL included with it to create a database to use in Django, but when I went and used the "python manage.py syncdb" command, I got this error:

I have checked the host, username, password and those are correct, I really want to use Django so if anyone can help me on this, that would be great.
You need to install mysql lib for windows.

You require a dependency
easy_install mysql-python

I try uninstall and install Django. But i still have this errors. Hope somebody can help me with it. Thanks
You shouldn't normally use django-admin, except when you do django-admin startproject.
After you have created the project, it is easier to use manage.py to run the dev server, because it takes care of setting the path and settings module for you.
./manage.py runserver
See the docs for more information.
Maybe you used another python version? It is python 2.7 now, and it seems you don't installed django properly for python2.7. You can try
python3 manage.py runserver
for using python3 in ubuntu (it is installed by default and accessibler with python3), or try to define how to run it with another python version.
I am new to django.
I get this error when I update settings.py with database and run
$python2.7 manage.py migrate
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb
module: libperconaserverclient.so.18: cannot open shared object file:
No such file or directory
Is it because of version of mysql ? if so which version should I use ?
$ python2.7 manage.py migrate

ImportError: cannot import name WSGIServerException
I heard that WSGIServerException was removed from django, so how do I get around this?
It's fixed on branch master, but it not yet available on PyPI.
You can simply install it from the source:
pip install -e git+https://github.com/gabrielfalcao/lettuce.git#egg=lettuce
the doc
The undocumented django.core.servers.basehttp.WSGIServerException has
been removed. Use socket.error provided by the standard library
instead.
i think you can tell "lettuce"'s author,0.0 .or: update "lettuce" python package.
my django app run with mysql, but when i try with mongodb then show thie error

** I have installed all necessary module installed, but when i want to runserver then show this message
I managed to fix the same error by using these packages on github:
https://github.com/django-nonrel/django-nonrel
https://github.com/django-nonrel/djangotoolbox
instead of the ones recommended on Django-Mongodb's setup page. Also, make sure to use the master branch of each, so as to not run into compatibility problems. If you're using pip, you can either pip install each of the following lines separately, or put them into your version of a requirements.txt file for your project:
git+https://github.com/django-nonrel/django-nonrel#master
git+https://github.com/django-nonrel/djangotoolbox#master
git+https://github.com/django-nonrel/mongodb-engine#master
And then run
pip install -r requirements.txt
Whenever I try to run a command like python manage.py syncdb, I get the following error:

django.core.exceptions.ImproperlyConfigured: Error loading cx_Oracle module: libclntsh.so.11.1: cannot open shared object file: No such file or directory
Is this resolvable on Ubuntu?
You need to install both cx_Oracle and an Oracle Client.
cx_Oracle can be found here.
An appropriate Oracle Client can be found here.
You will also need to set the LD_LIBRARY_PATH variable before you start your application. This can usually be done (for example):
export LD_LIBRARY_PATH=/usr/lib/oracle/11.2/client64/lib
Now you should be able to get past the cx_Oracle error message.
First things first - is this actually a Django problem, or just a cx_Oracle problem? Is cx_Oracle installed correctly? Can you connect to your Oracle database in a Python shell session?
import cx_Oracle
conn = cx_Oracle.connect('/') # user/password#dsn
cursor = conn.cursor()
If this doesn't raise an exception, you have connected successfully.
try easy_install cx_Oracle, it will compile cx_Oracle module from source
