openstackclient python error during server list
Question
I have installed openstackclient using following commands but somehow getting strange python error and not able to debug what is wrong here, hope python expert can give me some clue to find out what is wrong.
Install openstackclient on CentOS 7.6 (running python 2.7)
yum -y install epel-release
yum install python-pip
pip install python-openstackclient
pip install -U decorator
Run openstackclient
# source openrc
# openstack server list --debug
START with options: server list --debug

SyntaxError: invalid syntax
...is using syntax that only works with Python 3.x. Your system has Python 2.7. Assuming that you are using the correct version of EPEL, this looks like a packaging bug.
EDIT
I missed the fact that you were pip installing things, rather than relying on your package manager. First, don't do that: running pip install into the system Python libraries is going to break things at some point. If you're going to use pip , then install things into a virtual environment where it won't conflict with system tooling.
If you were installing things into a virtual environment, you could simply remove and re-create the virtual environment. I worry that you are going to discover other problems even if we are able to solve the more-itertools issue.
Given that more_itertools appears to be used by some of the code, I suspect that simply removing it will break things. You may be able to explicitly install an earlier, python 2.x compatible version of it. Try running:
pip install more-itertools==5.0.0
