python报错

supervisor的错误日志如下：

Traceback (most recent call last):   File "/home/himalayas/owengine/owprice/server.py", line 10, in <module>     import action   File "/home/himalayas/owengine/owprice/action/__init__.py", line 2, in <module>     from owprice import owPriceHandler   File "/home/himalayas/owengine/owprice/action/owprice.py", line 11, in <module>     from cjson import decode as json_decode   File "build/bdist.linux-x86_64/egg/cjson.py", line 7, in <module>   File "build/bdist.linux-x86_64/egg/cjson.py", line 4, in __bootstrap__   File "/home/himalayas/virtualenv/python2.7-fd/lib/python2.7/site-packages/pkg_resources.py", line 945, in resource_filename     self, resource_name   File "/home/himalayas/virtualenv/python2.7-fd/lib/python2.7/site-packages/pkg_resources.py", line 1633, in get_resource_filename     self._extract_resource(manager, self._eager_to_zip(name))   File "/home/himalayas/virtualenv/python2.7-fd/lib/python2.7/site-packages/pkg_resources.py", line 1661, in _extract_resource     self.egg_name, self._parts(zip_path)   File "/home/himalayas/virtualenv/python2.7-fd/lib/python2.7/site-packages/pkg_resources.py", line 1025, in get_cache_path     self.extraction_error()   File "/home/himalayas/virtualenv/python2.7-fd/lib/python2.7/site-packages/pkg_resources.py", line 991, in extraction_error     raise err 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 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.

解决方法：

去掉/home/himalayas/.python-eggs 这个目录用户组合other的x权限。

drwxr-xr-x   5 himalayas himalayas  4096 Aug 14 15:43 .python-eggs

drwxr--r--   5 himalayas himalayas  4096 Aug 14 15:43 .python-eggs

对程序启动没有影响，只是一个warning，但是对于supervisor来说对这个warning太敏感，所以导致使用supervisor启动的时候会启动不起来。
