Question

我安装了pandas模块。它需要最新版本的numpy，我有旧的一个pip安装了pandas模块，它也安装了所有依赖项，包括numpy。当我尝试在我的代码中导入pandas模块时，我收到以下错误：

/Library/Python/2.6/site-packages/pytz/__init__.py:35: 
UserWarning: Module dateutil was already imported from /System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/dateutil/__init__.pyc, but /Library/Python/2.6/site-packages is being added to sys.path
from pkg_resources import resource_stream

dateutil.__version__ == '2.0'):  # pragma: no cover
AttributeError: 'module' object has no attribute '__version__'

我无法弄清楚为什么会出现此错误以及如何纠正错误。

有人可以帮我解决这个问题吗？

谢谢！

我在尝试导入QTSK包时遇到了同样的问题，并显示完全相同的信息。

我发现在以下情况下不会显示该消息：

在导入QSTK之前导入numpy，
当我从/Library/Python/2.7/site-packages运行python时，因为pkg_resources在 /Library/Python/2.7/site-packages/distribute-0.6.32-py2.7.egg。

请注意第一行是空的，而不是/Library/Python/2.7/site-packages。
看起来像加载/查找包的顺序有问题。

PYTHONPATH = /库/ Python的/ 2.7 /站点包/分发-0.6.32-py2.7.egg
出口PYTHONPATH

问题已经消失。
