keystone-manage.py带来的问题，求解

我在ubuntu操作系统下安装了pycharm，有一个keystone K版的完整代码，（没有在操作系统中安装openstack的组件，只是源码）本来在pycharm里直接运行代码目录下的keystone-all.py脚本就可以把代码跑起来，跟安装了keystone模块的服务一样，但是今天手误执行了keystone-manage.py脚本，再执行keystone-all.py时便出现了如下错误：
/usr/bin/python2.7 /home/PycharmProjects/keystone-stable-kilo/bin/keystone-all

Original exception was:

很是费解，不知道该怎么解决
