安装PIL的坑

今天在centos中使用pip安装PIL死活不成功,报错:

  Could not find a version that satisfies the requirement PIL (from versions: )
  Some externally hosted files were ignored as access to them may be unreliable (use --allow-external PIL to allow).
  No matching distribution found for PIL

  

但是使用pip search PIL查找,源中确实有该包:

PIL                                  - Python Imaging Library

 

google之,得到如下办法(http://stackoverflow.com/questions/21242107/pip-install-pil-dont-install-into-virtualenv):

sudo pip install PIL --allow-external PIL --allow-unverified PIL

果然成功了。

 

但是程序运行时又报错:

font = ImageFont.truetype(os.path.join("fonts",font_type), font_size)
ImportError: The _imagingft C module is not installed

似乎是没有安装truetype扩展之类的。那就安装吧(http://stackoverflow.com/questions/4011705/python-the-imagingft-c-module-is-not-installed):

sudo yum install freetype-devel

 

然后卸载、重新安装PIL

sudo pip uninstall PIL
sudo pip install PIL --allow-external PIL --allow-unverified PIL

终于搞定了  

 

  

 

 

PS:之前还尝试过从官网下载PIL源码自己编译安装:

(参照:http://www.cnblogs.com/free--coder/archive/2012/09/12/2681361.html)

1.下载源码并解压:

wget http://effbot.org/downloads/Imaging-1.1.7.tar.gz
tar -xzvf Imaging-1.1.7.tar.gz 

2.编译安装(注意要root权限):

python setup.py build
python setup.py install  

 

安装倒是成功了,但是python脚本运行时报错:

/usr/lib64/python2.7/site-packages/PIL/Image.py:81: RuntimeWarning: The _imaging extension was built for another  version of Pillow or PIL
  warnings.warn(str(v), RuntimeWarning)
Traceback (most recent call last):
  File "captcha.py", line 3, in <module>
    import Image, ImageDraw, ImageFont, ImageFilter
  File "/usr/lib64/python2.7/site-packages/PIL/Image.py", line 65, in <module>
    raise ImportError("The _imaging extension was built for another "
ImportError: The _imaging extension was built for another  version of Pillow or PIL

似乎版本不对。。。。。

放弃了
