This page contains some advice about errors and problems commonly encountered during the development of Django applications.
“command not found: django-admin“¶
django-admin should be on your system path if you
installed Django via
python setup.py. If it’s not on your path, you can
find it in
site-packages is a directory
within your Python installation. Consider symlinking to django-admin from some place on your path, such as
django-admin doesn’t work but
django-admin.py does, you’re probably
using a version of Django that doesn’t match the version of this documentation.
django-admin is new in Django 1.7.
Mac OS X permissions¶
If you’re using Mac OS X, you may see the message “permission denied” when
you try to run
django-admin. This is because, on Unix-based systems like
OS X, a file must be marked as “executable” before it can be run as a program.
To do this, open Terminal.app and navigate (using the
cd command) to the
directory where django-admin is installed, then
run the command
sudo chmod +x django-admin.
I’m getting a
UnicodeDecodeError. What am I doing wrong?¶
This class of errors happen when a bytestring containing non-ASCII sequences is transformed into a Unicode string and the specified encoding is incorrect. The output generally looks like this:
UnicodeDecodeError: 'ascii' codec can't decode byte 0x?? in position ?: ordinal not in range(128)
The resolution mostly depends on the context, however here are two common pitfalls producing this error:
Your system locale may be a default ASCII locale, like the “C” locale on UNIX-like systems (can be checked by the
localecommand). If it’s the case, please refer to your system documentation to learn how you can change this to a UTF-8 locale.
You created raw bytestrings, which is easy to do on Python 2:
my_string = 'café'
Either use the
u''prefix or even better, add the
from __future__ import unicode_literalsline at the top of your file so that your code will be compatible with Python 3.2 which doesn’t support the
