熊猫模组进口错误

Question

我安装了熊猫模块。它需要最新版本的numpy，我让旧的pip安装了熊猫模块，它也安装了所有的依赖项，包括numpy。当我试图在代码中导入熊猫模块时，我会得到以下错误：

/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__'

我不知道为什么会有这个错误，以及如何纠正它。

有人能帮我吗？

谢谢!

在试图导入QTSK包时，我遇到了同样的问题，并显示了完全相同的消息。

我发现在以下情况下没有显示消息：

1. 在导入QSTK之前导入numpy，
2. 当我从/Library/ python /2.7/site-packages运行Python时，因为pkg_resources在pkg_resources中
3. 当我在/Library/Python2.7/ site.path /site中运行python时，： (“\n”.join(sys.path)) /Library/Python/2.7/site-packages/distribute-0.6.32-py2.7.egg /Library/Python/2.7/site-packages/cx_Oracle-5.1.2-py2.7-macosx-10.8-intel.egg

   /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip

   /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7

   /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload

   /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC

   /Library/Python/2.7/site-packages/PIL

   /Library/Python/2.7/site-packages/setuptools-0.6c11-py2.7.egg-info

1. 当我在/Library/Python2.7/ site.path运行时，site.path (“\n”.join(sys.path))

   /Library/Python/2.7/site-packages/distribute-0.6.32-py2.7.egg

   /Library/Python/2.7/site-packages/cx\_Oracle-5.1.2-py2.7-macosx-10.8-intel.egg

   /Library/Python/2.7/site-packages

   /Users/ssgam/QSTK

   /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip

   /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7

   /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin

   /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac

   /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages

   /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk

   /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old

   /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload

   /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC

   /Library/Python/2.7/site-packages/PIL

   /Library/Python/2.7/site-packages/setuptools-0.6c11-py2.7.egg-info

注意，第一行是空的，不是/Library/Python/2.7/site-packages。

1. 看起来包的加载/查找顺序出现了问题。
2. 设置后 PYTHONPATH=/Library/Python/2.7/site-packages/distribute-0.6.32-py2.7.egg 出口PYTHONPATH 问题已经解决了。

还有你的问题..。相同的
