Question

编译libjpeg v8，PIL 1.1.7并导入_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：

我使用的是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

我正在使用Python 2.6

我已遵循以下指南：

Answer 1

请在此处查看解释：Why can't Python find shared objects that are in directories in sys.path?

快速解决方法是将包含libjpeg.so.8的目录添加到/etc/ld.so.conf文件，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。（它发生了：http://opensourcehacker.com/2011/08/31/zend-server-installation-potentially-kills-your-ssh/）

Answer 3

从源代码编译库也可以：http://www.ijg.org/files/

如果您使用的是类似Unix的系统，请确保使用jpegsrc.v8.tar.gz。 jpegsr8.zip似乎是MS版本，在构建时会引发所有标准格式问题。
