oslo配置获取错误：引发NoSuchOptError（name）oslo_config.cfg.NoSuchOptError：组[DEFAULT]中没有这样的选项重复项

Question

当我遵循此oslo config tutorial时：

在2:00中，那里：

from oslo_config import cfg

from pprint import pprint

res = [{k:v} for k, v in cfg.CONF.iteritems()]

pprint(res)

在本教程中，打印[]，

但是在我的PyCharm中，有一个

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/oslo_config/cfg.py", line 2193, in __getattr__
    return self._get(name)
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/oslo_config/cfg.py", line 2627, in _get
    value, loc = self._do_get(name, group, namespace)
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/oslo_config/cfg.py", line 2645, in _do_get

    raise NoSuchOptError(opt_name, group)
oslo_config.cfg.NoSuchOptError: no such option iteritems in group [DEFAULT]

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/Users/bush/Desktop/TestIOS/TestPython/testDemo01/testDemo01/test16.py", line 15, in <module>
    res = [{k:v} for k, v in cfg.CONF.iteritems()]

    raise NoSuchOptError(name)
oslo_config.cfg.NoSuchOptError: no such option iteritems in group [DEFAULT]

在oslo_config.cfg的较新版本中，可以根据需要使用items()：

es = [{k:v} for k, v in cfg.CONF.items()]

pprint(res)
