failed to install django-chronograph in django 1.7

问题

I tried to install django-chronograph to django-1.7 for assigning scheduled task in my django web-app.

I followed the instruction as shown here but it gives me the following error when running python manage.py makemigrations or python manage.py syncdb:

user@(none):~/mysite$ python manage.py makemigrations
Traceback (most recent call last):

Is it django-chronograph not supported by django-1.7?

回答1:

I've never heard of this package, but if you search for that error you will find that that import path hasn't worked since Django 1.6.

It could be that it's just the PyPI version that's old, and that the master branch works fine. However, the last commit to this package was in March 2013, and there's an open issue on the project's bitbucket page indicating that it fails to work on 1.6, so I doubt it.

In sum, it appears that this package supports neither Django 1.6 nor 1.7.

回答2:

They already committed a fix, so to get rid of this error, don't go through:

pip install django-chronograph

I've just installed on Django 1.8 without issues (so far..) using:

pip install -e hg+https://bitbucket.org/wnielson/django-chronograph@f561106f6aaab62f2817e08e51c799320fd916d9#egg=django-chronograph
