* Hi everyone, I've been trying to run ironic on devstack and finally facing following errors (I've tried running ./clean.sh and again re running ./stack.sh )
1. On running ./stack.sh I face _**error on exit**_
```Attempting
    Found existing installation: simplejson 3.13.2
ERROR: Cannot uninstall 'simplejson'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

+./stack.sh:exit_trap:568                  exit 1
```

2. I still tried and ran further instructions given here https://docs.openstack.org/ironic/stein/contributor/dev-quickstart.html#deploying-ironic-with-devstack
and have faced following error 
```
Failed to discover available identity versions when contacting http://192.168.1.108/identity. Attempting to parse version from URL.
Could not determine a suitable URL for the plugin

```

Is anyone familiar with the problem, I feel a bit clueless here.
