Python:从其他地方导入？

Question

bash-4.1$ airflow initdb
Traceback (most recent call last):
  File "/u/bin/airflow", line 4, in <module>
    from airflow import configuration
  File "/u/lib/python2.7/site-packages/airflow/__init__.py", line 31, in <module>
    from airflow.models import DAG
  File "/u/lib/python2.7/site-packages/airflow/models.py", line 53, in <module>
    from croniter import croniter
  File "/u/lib/python2.7/site-packages/croniter/__init__.py", line 3, in <module>
    from .croniter import croniter
  File "/u/lib/python2.7/site-packages/croniter/croniter.py", line 8, in <module>
    from dateutil.relativedelta import relativedelta
  File "build/bdist.linux-x86_64/egg/dateutil/relativedelta.py", line 5, in <module>
ImportError: cannot import name integer_types

但解释器中没有问题：

bash-4.1$ /u/bin/python2.7
Python 2.7.5 (default, Oct 17 2013, 14:04:34) 
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import croniter
>>> 

我假设它与以下内容有关：

File "build/bdist.linux-x86_64/egg/dateutil/relativedelta.py", line 5, in <module>

所以在解释器中它使用来自/u/lib/python2.7的dateutil，而在airflow中它使用来自build/bdist.linux-x86_64/egg/dateutil的datutil？

我甚至不知道build/bdist.linux-x86_64/egg/dateutil在哪。

有人能告诉我到底是怎么回事吗?如何告诉airflow从正确的dateutil导入

您需要安装Six python包。

只需制作一个pip install six
