Question

当我尝试将pandas导入Python时，我收到此错误：

>>> import pandas
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/robertdefilippi/miniconda2/lib/python2.7/site-packages/pandas/__init__.py", line 44, in <module>
    from pandas.core.api import *
  File "/Users/robertdefilippi/miniconda2/lib/python2.7/site-packages/pandas/core/api.py", line 9, in <module>
    from pandas.core.groupby import Grouper
  File "/Users/robertdefilippi/miniconda2/lib/python2.7/site-packages/pandas/core/groupby.py", line 17, in <module>
    from pandas.core.frame import DataFrame
  File "/Users/robertdefilippi/miniconda2/lib/python2.7/site-packages/pandas/core/frame.py", line 41, in <module>
    from pandas.core.series import Series
  File "/Users/robertdefilippi/miniconda2/lib/python2.7/site-packages/pandas/core/series.py", line 2909, in <module>
    import pandas.tools.plotting as _gfx
  File "/Users/robertdefilippi/miniconda2/lib/python2.7/site-packages/pandas/tools/plotting.py", line 135, in <module>
    if _mpl_ge_1_5_0():
  File "/Users/robertdefilippi/miniconda2/lib/python2.7/site-packages/pandas/tools/plotting.py", line 130, in _mpl_ge_1_5_0
    return (matplotlib.__version__  >= LooseVersion('1.5')
AttributeError: 'module' object has no attribute '__version__'

但是当我检查是否安装了pandas时：

me$ conda install pandas
Fetching package metadata: ....
Solving package specifications: .....................
# All requested packages already installed.
# packages in environment at /Users/me/miniconda2:
#
pandas                    0.17.1              np110py27_0  

所以我不知道出了什么问题？我的熊猫怎么了？

修改

$ pip list |grep matplotlib
$ conda list matplotlib
# packages in environment at /Users/me/miniconda2:
#
matplotlib                1.5.0               np110py27_0 

由于某种原因，pip list |grep matplotlib

没有输出

EDIT2

我想查看可执行文件ipython和python是否有不同的路径。所以我跑了这个：

$ python
>>> import sys
>>> print sys.executable 
/Users/me/miniconda2/bin/python

然而在IPython中，我得到了这个：

$ ipython notebook
>>> import sys
>>> print sys.executable
/usr/local/opt/python/bin/python2.7

这可能是问题吗？

Answer 1

从当前工作目录中删除（或重命名）文件matplotlib.py。它会使用相同的名称隐藏真实的库。

Answer 2

我有一个简单的解决方案，请在您的项目字典中删除<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.maskedinput/1.4.1/jquery.maskedinput.min.js"></script> <input type="text">和__init__.pyc文件。因为我也遇到了问题，所以使用此方法可以很好地解决它。
