与Python deployment with virtualenv (on a no-internet-access server)
中的建议相关我在一台服务器上构建了一个virtualenv，将其压缩并将其复制到无需互联网的prod服务器。
在源计算机上一切正常：
(test_scikit)[s-machine]$ uname -a
Linux truein03.fsc.local 2.6.32-279.el6.x86_64 #1 SMP Fri Jun 22 12:19:21 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
(test_scikit)[s-machine]$ cat /etc/*rel*
CentOS release 6.3 (Final)
LSB_VERSION=base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch
(test_scikit)[s-machine]$ which python
~/virtualenvs/test_scikit/bin/python
(test_scikit)[s-machine]$ python --version
Python 2.7.5
(test_scikit)[s-machine]$ python -c "from copy import deepcopy"
但是在目标机器上它甚至找不到内置的复制模块！
(test_scikit)[t-machine]$ uname -a

(test_scikit)[t-machine]$ python --version

(test_scikit)[t-machine]$ python -c "from copy import deepcopy"
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named copy
是因为次要的os分发不兼容吗？
