升级python成像库(PIL)时,它告诉我"JPEG支持不可用"

Question

使用ubuntu 13.10,python 2.7.5:

>>> import _imaging, Image
>>> from PIL import Image, ImageDraw, ImageFilter, ImageFont
>>> im = Image.new('RGB', (300,300), 'white')
>>> draw = ImageDraw.Draw(im)
>>> font = ImageFont.truetype('arial.ttf', 14)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/PIL/ImageFont.py", line 218, in truetype
    return FreeTypeFont(filename, size, index, encoding)
  File "/usr/local/lib/python2.7/dist-packages/PIL/ImageFont.py", line 134, in __init__
    self.font = core.getfont(file, size, index, encoding)
  File "/usr/local/lib/python2.7/dist-packages/PIL/ImageFont.py", line 34, in __getattr__
    raise ImportError("The _imagingft C module is not installed")
**ImportError: The _imagingft C module is not installed**
>>>

那么为什么会这样呢？我该如何解决？我按照以下说明在本主题的底部找到了:

pip uninstall PIL
apt-get install libjpeg-dev
apt-get install libfreetype6-dev
apt-get install zlib1g-dev
apt-get install libpng12-dev
pip install PIL --upgrade

但在升级PIL时,看看我看到的内容:

--------------------------------------------------------------------
PIL 1.1.7 SETUP SUMMARY
--------------------------------------------------------------------
version       1.1.7
platform      linux2 2.7.5+ (default, Sep 19 2013, 13:48:49)
              [GCC 4.8.1]
--------------------------------------------------------------------
*** TKINTER support not available
*** JPEG support not available
*** ZLIB (PNG/ZIP) support not available
*** FREETYPE2 support not available
*** LITTLECMS support not available
--------------------------------------------------------------------

这是正常对所有这些项目的支持不是可用？我该如何解决这个问题？

Answer 1

PIL基本上死了,叉子Pillow真的是你应该使用的.你需要通过它导入它

from PIL import Image, ...

它维护了所有功能PIL,并增加了很多功能,包括Python 3兼容性.此外,它正在积极开发中,与之不同PIL,因此您发现的任何错误实际上都有可能得到修复 - 与功能请求相同.

您可以PIL通过运行来安装它(卸载后)

pip install Pillow

我相信Ubuntu有一个软件包,但我的VM目前让我头疼,我无法检查......
