python-2.7 – IOError：OS X 10.10上没有编码器jpeg

概述我试图安装 Python Image Library,并且有消息告诉我安装成功 -------------------------------------------------------------------- PIL 1.1.7 SETUP SUMMARY ----------------------------------------------------------- 我试图安装 Python Image library,并且有消息告诉我安装成功

--------------------------------------------------------------------    PIL 1.1.7 SETUP SUMMARY    --------------------------------------------------------------------    version       1.1.7    platform      darwin 2.6.9 (unkNown,Sep  9 2014,15:05:12)                  [GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)]    --------------------------------------------------------------------    --- TKINTER support available    --- JPEG support available    --- ZliB (PNG/ZIP) support available    --- FREETYPE2 support available    *** liTTLECMS support not available    --------------------------------------------------------------------

但是当我运行代码时,得到一些错误消息,可能告诉我我没有安装JPEG库

/System/library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 /Users/tian/PycharmProjects/helloworld/image_test.pyTraceback (most recent call last):  file "/Users/tian/PycharmProjects/helloworld/image_test.py",line 35,in <module>    image.save('code.jpg','jpeg')  file "/library/Python/2.7/site-packages/PIL/Image.py",line 1439,in save    save_handler(self,fp,filename)  file "/library/Python/2.7/site-packages/PIL/JpegImagePlugin.py",line 471,in _save    Imagefile._save(im,[("jpeg",(0,0)+im.size,rawmode)])  file "/library/Python/2.7/site-packages/PIL/Imagefile.py",line 495,in _save    e = Image._getencoder(im.mode,e,a,im.encoderconfig)  file "/library/Python/2.7/site-packages/PIL/Image.py",line 401,in _getencoder    raise IOError("encoder %s not available" % encoder_name)IOError: encoder jpeg not available

当我在Google中搜索此错误的原因时,大部分解决方案是重新安装PIL,但是当我安装PIL时,我得到了“JPEG支持可用”消息,因此它不应该由JPEG库引起.那我该怎么解决这个问题呢？

我的 *** 作系统是OS X Yosemite 10.10

解决方法 我通过使用Pillow而不是PIL解决了这个问题,并使用“form PIL import Image”而不是“import Image”. 总结
