Python:在特殊环境中执行代码对象

Question

这是我想更改 LD_LIBRARY_PATH 来执行代码的代码:

#!/usr/bin/python
import os

code='''
import os
print os.getenv("LD_LIBRARY_PATH");
import wrap
'''

os.environ['LD_LIBRARY_PATH'] = '/home/dma/python'
os.environ["PYTHONPATH"] = '/home/dma/python'

exec code

输出为:

/home/dma/python
Traceback (most recent call last):
  File "./test.py", line 13, in ?
    exec code
  File "<string>", line 4, in ?
ImportError: example.so: cannot open shared object file: No such file or directory

注意:test.py依赖于wrap.so，wrap.so依赖于example.so

有没有办法在特殊环境下执行代码对象？

谢谢 DMA

似乎 example.so 不在 /home/dma/python 中。
