在django 1.7中安装django计时器失败

Question

我尝试在我的django web应用程序中安装django-chronograph到django-1.7来分配预定的任务。

我按照here所示的说明进行了操作，但在运行python manage.py makemigrations或python manage.py syncdb时出现以下错误

user@(none):~/mysite$ python manage.py makemigrations
Traceback (most recent call last):
  File "manage.py", line 10, in <module>

    from django.conf.urls.defaults import patterns, url
ImportError: No module named defaults

是django-1.7不支持的django-chronograph吗

Answer 1

我从来没有听说过这个包，但是如果你搜索那个错误，你会找到那个that import path hasn't worked since Django 1.6。

可能只是PyPI版本太旧了，而且主分支工作正常。然而，这个包的the last commit是在2013年3月，在项目的bitbucket页面上有an open issue表明它无法在1.6上工作，所以我对此表示怀疑。

总而言之，这个包似乎既不支持Django 1.6也不支持1.7。

Answer 2

They already committed a fix，所以要消除这个错误，不要执行以下命令：

pip install django-chronograph

我刚刚在Django 1.8上安装，没有问题(到目前为止..)使用：

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