关于PYTHON_EGG_CACHE无权限的问题

Perhaps your account does not have write access to this directory?  You can

change the cache directory by setting the PYTHON_EGG_CACHE environment

variable to point to an accessible directory.

pkg_resources.ExtractionError: Can't extract file(s) to egg cache



The following error occurred while trying to extract file(s) to the Python egg

cache:



  [Errno 13] Permission denied: '/root/.python-eggs'



The Python egg cache directory is currently set to:



  /root/.python-eggs

　　上面错误是我在php执行python脚本的时候出现的问题：

解决办法是在开始的文件前面加上了这段代码

import os,sys





os.environ['PYTHON_EGG_CACHE'] = '/tmp/.python-eggs'

abspath = os.path.dirname(__file__)

sys.path.append(abspath)

os.chdir(abspath)
