运行 gnocchi resource list --type image，报AttributeError: _Environ instance has no attribute ‘set‘的解决

openstack安装和配置好ceilometer服务，运行命令后报错

[root@controller]# gnocchi resource list  --type image 

报的错误如下：

Traceback (most recent call last):
  File "/usr/bin/gnocchi", line 10, in <module>
    sys.exit(main())
  File "/usr/lib/python2.7/site-packages/gnocchiclient/shell.py", line 253, in main
    return GnocchiShell().run(args)
  File "/usr/lib/python2.7/site-packages/gnocchiclient/shell.py", line 100, in __init__
    deferred_help=True,

    self.parser = self.build_option_parser(description, version)
  File "/usr/lib/python2.7/site-packages/gnocchiclient/shell.py", line 131, in build_option_parser
    os.environ.set("OS_AUTH_TYPE","password")
AttributeError: _Environ instance has no attribute 'set'

AttributeError: _Environ instance has no attribute 'set'，是python相关的。可能是函数没有相应的值，应该怎么该，琢磨了好久，尝试了几次，总结出两个办法消除这个错误。

方法一：
 

 vim /usr/lib/python2.7/site-packages/gnocchiclient/shell.py
#将

        # NOTE(jd) This is a workaroun for people using Keystone auth with the
        # CLI. A lot of rc files do not export OS_AUTH_TYPE=password and
        # assumes it is the default. It's not in that case, but since we can't
        # fix all the rc files of the world, workaround it here.
        if ("OS_PASSWORD" in os.environ and
           "OS_AUTH_TYPE" not in os.environ):
            os.environ.set("OS_AUTH_TYPE","password")
#修改为

        # NOTE(jd) This is a workaroun for people using Keystone auth with the
        # CLI. A lot of rc files do not export OS_AUTH_TYPE=password and
        # assumes it is the default. It's not in that case, but since we can't
        # fix all the rc files of the world, workaround it here.
        if ("OS_PASSWORD" in os.environ and
           "OS_AUTH_TYPE" not in os.environ):
            os.environ.setdefault("OS_AUTH_TYPE","password")

就是将 os.environ.set("OS_AUTH_TYPE","password")修改为os.environ.setdefault("OS_AUTH_TYPE","password")

方法二：

#将
        # NOTE(jd) This is a workaroun for people using Keystone auth with the

        if ("OS_PASSWORD" in os.environ and
           "OS_AUTH_TYPE" not in os.environ):
            os.environ.set("OS_AUTH_TYPE","password")
#修改为

        if ("OS_PASSWORD" in os.environ and
           "OS_AUTH_TYPE" not in os.environ):
            os.environ["OS_AUTH_TYPE"]="password"

就是将os.environ.set("OS_AUTH_TYPE","password")修改为os.environ["OS_AUTH_TYPE"]="password"

以上两种方法供借鉴
