Python为什么找不到sys.path目录中的共享对象？

Question

我正在尝试导入pycurl：

$ python -c "import pycurl"

Traceback (most recent call last):

File "<string>", line 1, in <module>

ImportError: libcurl.so.4: cannot open shared object file: No such file or directory

现在，libcurl.so.4在中/usr/local/lib。如您所见，这是在sys.path：

$ python -c "import sys; print(sys.path)"

['', '/usr/local/lib/python2.5/site-packages/setuptools-0.6c9-py2.5.egg', 

'/usr/local/lib/python25.zip', '/usr/local/lib/python2.5', 

'/usr/local/lib/python2.5/plat-linux2', '/usr/local/lib/python2.5/lib-tk', 

'/usr/local/lib/python2.5/lib-dynload', 

'/usr/local/lib/python2.5/sitepackages', '/usr/local/lib', 

'/usr/local/lib/python2.5/site-packages']

任何帮助将不胜感激。
