在拿到 O'Reilly 的书之前,我在玩 Python 的 pandas 包。当我在成功安装 xcode 和 EPDFree 后尝试安装 pandas 时,使用 easy_install 安装 pandas 时出现了许多警告,当我测试 pandas 是否正常工作时,很明显不是。我曾多次尝试删除并重新安装 pandas 和 Numpy,但均未成功。我是新手,所以肯定做错了什么。
这是我在运行 Python 并尝试导入 pandas 和 Numpy 时得到的:
$ python
Python 2.7.2 (default, Oct 11 2012, 20:14:37)

>>> import numpy

>>> import pandas
No module named numpy

File "/Library/Python/2.7/site-packages/pandas-0.12.0-py2.7-macosx-10.8-intel.egg/pandas/__init__.py", line 6, in <module>
from . import hashtable, tslib, lib
File "numpy.pxd", line 157, in init pandas.hashtable (pandas/hashtable.c:19547)
ImportError: No module named numpy
有没有办法可以解决这个问题或重新开始整个安装?
以下是我尝试安装 pandas 和 Numpy 时的更多信息:
