我激活了 virtualenv 并且正在运行命令
celery -A dnslookup worker --loglevel=info
抛出
Traceback (most recent call last):
File "/Users/myuser/dev/project-backend-ENV/bin/celery", line 5, in <module>
from pkg_resources import load_entry_point
File "/Users/myuser/dev/project-backend-ENV/lib/python2.7/site-packages/setuptools- 0.6c11-py2.7.egg/pkg_resources.py", line 2607, in <module>
File "/Users/myuser/dev/project-backend-ENV/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg/pkg_resources.py", line 565, in resolve
pkg_resources.DistributionNotFound: python-dateutil>=1.5,<2.0
但是 python-dateutil 安装在我的 virtualenv 中。
如何解决这个问题？
最佳答案
我猜测您使用的 dateutil 版本太新了。默认情况下，将 dateutil 安装到新的 virtualenv 会得到 dateutil 版本 2.1，这是行不通的(正如您的错误消息所指出的那样)。来自 Celery changelog :
Dependency lists now explicitly specifies that we don’t want python-dateutil 2.x, as this version only supports py3k.
If you have installed dateutil 2.0 by accident you should downgrade to the 1.5.0 version:
pip install -U python-dateutil==1.5.0
关于python - celery 没有找到 python-dateutil，尽管它已安装，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12322767/
