Problems running ``django-admin``

2014-07-26 13:21:52 +02:00
|
|
|
:doc:`django-admin </ref/django-admin>` should be on your system path if you
|
2012-08-05 00:05:57 +02:00
|
|
|
installed Django via ``python setup.py``. If it's not on your path, you can
|
|
|
|
|
find it in ``site-packages/django/bin``, where ``site-packages`` is a directory
|
2014-07-26 13:21:52 +02:00
|
|
|
within your Python installation. Consider symlinking to :doc:`django-admin
|
2012-08-05 00:05:57 +02:00
|
|
|
</ref/django-admin>` from some place on your path, such as
|
2012-12-15 15:25:54 +01:00
|
|
|
:file:`/usr/local/bin`.

|
|
|
If ``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.

macOS permissions

If you're using macOS, you may see the message "permission denied" when
|
2014-07-26 13:21:52 +02:00
|
|
|
you try to run ``django-admin``. This is because, on Unix-based systems like
|
2017-04-23 22:06:12 +02:00
|
|
|
macOS, a file must be marked as "executable" before it can be run as a program.
|
2012-12-15 15:25:54 +01:00
|
|
|
To do this, open Terminal.app and navigate (using the ``cd`` command) to the
|
2014-07-26 13:21:52 +02:00
|
|
|
directory where :doc:`django-admin </ref/django-admin>` is installed, then
|
|
|
|
|
run the command ``sudo chmod +x django-admin``.

Miscellaneous

|
|
|
|
=============
|
|
|
|
|
|
|
|
|
|
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 ``locale`` command). If it's the
|
|
|
|
|
case, please refer to your system documentation to learn how you can change
|
|
|
|
|
this to a UTF-8 locale.
