安裝PIL的坑

今天在centos中使用pip安裝PIL死活不成功，報錯：

  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，源中確實有該包：

PIL                                  - Python Imaging Library

 

google之，得到如下辦法（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。

 

但是程序運行時又報錯：

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

似乎是沒有安裝truetype擴展之類的。那就安裝吧(http://stackoverflow.com/questions/4011705/python-the-imagingft-c-module-is-not-installed):

sudo yum install freetype-devel

 

然后卸載、重新安裝PIL

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

終於搞定了　　

 

　　

 

 

PS:之前還嘗試過從官網下載PIL源碼自己編譯安裝：

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

1.下載源碼並解壓：

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

2.編譯安裝（注意要root權限）：

python setup.py build
python setup.py install  

 

安裝倒是成功了，但是python腳本運行時報錯：

/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

似乎版本不對。。。。。

放棄了
