我已按照此链接在我的虚拟机上部署 devstack。当我在 VM 中执行 ./stack.sh 脚本时，一段时间后出现以下错误：
keystone endpoint-create: error: argument --service-id/--service_id: expected one argument
++ failed
++ local r=2
+++ jobs -p
++ kill
++ set +o xtrace
脚本终止时不提供任何信息，例如访问 Horizon 的主机和运行脚本所用的时间。我使用 NAT 作为我的虚拟机网络配置，因为我无法使用桥接模式连接到我的网络。
尝试从 Web 浏览器访问 Horizon 时没有收到任何响应。当我尝试执行 stack.sh（前面没有 ./unstack.sh）时，我得到堆栈已经在运行的错误。请注意，我在代理服务器后面，这分别是我在主机和来宾机器上的网络配置：

我的 localrc 文件配置如下：
FLOATING_RANGE=192.168.1.224/27
FIXED_RANGE=10.11.12.0/24
FIXED_NETWORK_SIZE=256
FLAT_INTERFACE=eth0
ADMIN_PASSWORD=password
MYSQL_PASSWORD=password
RABBIT_PASSWORD=password
SERVICE_PASSWORD=password
SERVICE_TOKEN=tokentoken
请注意，我在代理服务器后面。谷歌搜索这个错误返回了一些页面，这些页面表明可以通过使用 devstack 机器的主 IP 地址设置“no_proxy”变量来解决这个问题。

我不知道在哪里添加这些设置或如何解决整个梯形失真错误。非常感谢任何帮助。提前致谢。
