导入克隆Git rep中用C编写的Python模块时出错

Question

我刚刚克隆了NiPy repository，但是当我试图导入nipy.algorithms.registration时，我得到了以下错误：

In [1]: import nipy.algorithms.registration
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-1-17bae03bf7b5> in <module>()
----> 1 import nipy.algorithms.registration

/home/despo/dbliss/nipy/nipy/algorithms/__init__.py in <module>()
      7 __docformat__ = 'restructuredtext'
      8 
----> 9 import statistics
     10 import fwhm, interpolation, kernel_smooth, diagnostics
     11

      6 __docformat__ = 'restructuredtext'
      7 
----> 8 from . import intvol, rft, onesample, formula
      9 from ._quantile import _quantile as quantile, _median as median
     10 

ImportError: cannot import name intvol

我发现存储库中有两个名为intvol的文件：intvol.c和国际卷pyx. 发生什么事？在
