我对MACOSX的了解不多。我是MAC新手。我想在MAC上使用Python调整pgm图像的大小。但是显示错误。
这是python代码
from PIL import Image
img=Image.open('secretImage.pgm','r')
columnsize,rowsize=img.size
img = img.resize((2*rowsize,2*columnsize), Image.BILINEAR) # Resize it.
img.save('resized.pgm' ) # Save it back to disk.
错误:
apples-MacBook-Air:untitled folder apple$ python NewFile.py
Traceback (most recent call last):
File "NewFile.py", line 4, in <module>
img = img.resize((2*rowsize,2*columnsize), Image.BILINEAR) # Resize it.
File "/Library/Python/2.7/site-packages/PIL/Image.py", line 1290, in resize
self.load()
File "/Library/Python/2.7/site-packages/PIL/ImageFile.py", line 164, in load
self.load_prepare()
File "/Library/Python/2.7/site-packages/PIL/ImageFile.py", line 231, in load_prepare
self.im = Image.core.new(self.mode, self.size)
File "/Library/Python/2.7/site-packages/PIL/Image.py", line 37, in __getattr__
raise ImportError("The _imaging C module is not installed")
ImportError: The _imaging C module is not installed

我该如何解决?
