python报错

supervisor的错误日志如下：

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。
