virtualenv中解决报错：ImportError: No module named time

其中：2env为使用virtualenv创建的虚拟环境，xxx.py为我要运行的python程序

(2env) [root@xxxx]$ /gunicorn  xxx.py
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
Traceback (most recent call last):
File "/xxxx/env/bin/gunicorn", line 5, in <module>
from pkg_resources import load_entry_point
File "/xxx/env/lib/python2.7/site-packages/pkg_resources.py", line 16, in <module>
import sys, os, time, re, imp, types, zipfile, zipimport
ImportError: No module named time

解决办法：
将可正常运行同样程序机器下目录/xxxx/2env/lib/python2.7/site-packages目录下的两个文件夹
pip和pkg_resources打包压缩，拷贝到目标机器同样的目录下解压，

再次执行你的程序：/gunicorn  xxx.py  可正常执行
