PIL - libjpeg.so.8:无法打开共享对象文件:没有这样的文件或目录

Question

编译libjpeg v8,PIL 1.1.7和导入_imaging在系统Python上工作,但在virtualenv中发出此错误:

libjpeg.so.8: cannot open shared object file: No such file or directory

这是在virtualenv中使用python -v解释器运行的错误

>>> import _imaging
dlopen("/home/ygamretuta/dev/py/django/lib/python2.6/site-packages/PIL/_imaging.so", 2);
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: libjpeg.so.8: cannot open shared object file: No such file or directory

以下是路径:

我正在使用Ubuntu 10.10,这是uname-a输出:

Linux ygam-desktop 2.6.35-28-generic #49-Ubuntu SMP Tue Mar 1 14:40:58 UTC 2011 i686 GNU/Linux

我使用的是Python 2.6

我已经按照以下指南:

Answer 1

请参阅此处的解释:为什么Python无法找到sys.path中目录中的共享对象？

快速解决方法是将包含的目录添加libjpeg.so.8到您的/etc/ld.so.conf文件中,然后运行ldconfig

Answer 2

此外,如果您正在进行本地Python安装,您还可以使用LD_LIBRARY_PATH环境变量控制会话级别的动态链接::

 export LD_LIBRARY_PATH=/srv/plone/python/python-2.6/lib
 python
 import _imaging
 ...

这样你甚至不会意外地破坏你自己的操作系统.(它发生在:http://opensourcehacker.com/2011/08/31/zend-server-installation-potentially-kills-your-ssh/)
