ImportError: No module named south.v2 but I don't use south

Question

我在新安装的 lubuntu 16.04 上运行ning django 1.9。我创建了一个虚拟环境并从 github 克隆了我的存储库。我尝试运行 ./manage.py runserver 并收到错误消息：

ImportError: No module named south.v2

我检查过其他类似的问题，但它们似乎暗示我是从南方升级的，我已经多年没有使用过，也从未在这个存储库上升级。

这是我的 pip 冻结结果：

chardet==2.2.1
Django==1.9.2
django-appconf==0.6
django-bootstrap3==6.2.2
django-csvimport==1.0
django-debug-toolbar==1.4
django-extensions==1.5.0
docutils==0.12
gunicorn==19.4.5
Markdown==2.6.5
Pygments==2.1.1
six==1.7.3
sqlparse==0.1.18

将您的 django-extension 更新到最新版本 1.6.7：

pip install django-extensions==1.6.7

旧版本使用 south 进行迁移，而新版本使用 1.6 版本中引入的 django 默认迁移

ImportError: No module named south.v2 but I don't use south

ImportError: No module named south.v2 but I don't use south

django

python-2.7
