macos - 导入 matplotlib 时 numpy 的版本错误

Question

当我

import matplotlib

我没有收到任何错误，但是当我

import matplotlib.pyplot

我得到

RuntimeError: module compiled against API version 8 but this version of numpy is 7
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Python/2.7/site-packages/matplotlib/pyplot.py", line 24, in <module>
    import matplotlib.colorbar
  File "/Library/Python/2.7/site-packages/matplotlib/colorbar.py", line 27, in <module>
    import matplotlib.artist as martist
  File "/Library/Python/2.7/site-packages/matplotlib/artist.py", line 8, in <module>
    from transforms import Bbox, IdentityTransform, TransformedBbox, \
  File "/Library/Python/2.7/site-packages/matplotlib/transforms.py", line 35, in <module>
    from matplotlib._path import (affine_transform, count_bboxes_overlapping_bbox,
ImportError: numpy.core.multiarray failed to import

这看起来像 version error ;但是 yolk说我有一个最新版本，和 pip说一切都是最新的，不会帮助“真正”更新事物。

我该怎么做才能确保必要的软件包“真正”是最新的，以避免出现此错误；哪些包需要“真正”更新(matplotlib；numpy；其他？)。

卸载和重新安装 numpy(使用 pip)没有帮助。

pip 是否以某种方式让我最近将 matplotlib 更新为“太新”的版本，而 numpy 的 pip 版本滞后？

我的 sys.path是:

['',
'/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/Extras/lib/python',  
'/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']

并且 Scypi 堆栈安装在 site-packages它由 pip 维护。 OS X 10.9，Apple Python 2.7.5，所有包版本都是通过 pip 在 PiPy 中找到的版本。

在这种情况下强制重新安装有效，因为在类似情况下通常会这样做:

sudo pip install -U --force-reinstall scipy
