Question

为什么pip show告诉我我有numpy版本1.13.1，而Pandas认为我有numpy版本1.8.0rc1

导入pandas时出现以下错误。有人能告诉我如何解决这个问题。

导入pandas

 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "/Library/Python/2.7/site-packages/pandas/__init__.py", line 23, in <module>
     from pandas.compat.numpy import *
   File "/Library/Python/2.7/site-packages/pandas/compat/numpy/__init__.py", line 24, in <module>
     'this pandas version'.format(_np_version))
 ImportError: this version of pandas is incompatible with numpy < 1.9.0
 your numpy version is 1.8.0rc1.
 Please upgrade numpy to >= 1.9.0 to use this pandas version

这些是我机器上numpy的详细信息

 pip show numpy 
 Name: numpy
 Version: 1.13.3
 Summary: NumPy: array processing for numbers, strings, records, and objects.

这些是我机器上的大熊猫的详细信息

 Name: pandas

我尝试过卸载＆amp;重新安装numpy

 sudo  pip uninstall numpy
 sudo  pip install numpy

如果有任何依赖性问题，我已检查过pandas

 pip check pandas         
 No broken requirements found.

我尝试取消链接和重新连接numpy

 brew unlink numpy        
 brew link numpy

 Linking /usr/local/Cellar/numpy/1.13.3... 
 Error: Could not symlink bin/f2py
 Target /usr/local/bin/f2py
 already exists. You may want to remove it:
   rm '/usr/local/bin/f2py'

 To force the link and overwrite all conflicting files:
   brew link --overwrite numpy

 To list all files that would be deleted:
   brew link --overwrite --dry-run numpy

在python REPL中（我使用ipython）

template<typename Mixin, typename Ctor>
struct EntityFactory : Mixin, Entity
{
    EntityFactory() = Ctor;
    void preUpdate(float dt)
    {Mixin::mixinPreUpdate(dt);}
    void update(float dt)
    {Mixin::mixinUpdate(dt);}
    void lateUpdate(float dt)
    {Mixin::mixinLateUpdate(dt);}
 };

这将显示numpy来自哪里，而pandas则会这样做

In [98]: import numpy as np

In [99]: np.__version__
Out[99]: '1.13.3'

In [100]: np.__file__
Out[100]: '/Users//anaconda/lib/python2.7/site-packages/numpy/__init__.pyc'

终端窗口中的

输入In [103]: import pandas as pd In [104]: pd.__version__ Out[104]: u'0.20.3' In [105]: pd.__file__ Out[105]: '/Users//anaconda/lib/python2.7/site-packages/pandas/__init__.pyc'
