Missing dependency on configure home server

Hi,

I'm trying to configure my own matrix home server on EC2 Amazon Linux AMI and it's have following packages

1. Python 2.7.12
2. pip 9.0.1 from /usr/lib/python2.7/dist-packages (python 2.7)
3. jsonschema==2.6.0
4. frozendict==1.2
5. unpaddedbase64==1.1.0
6. canonicaljson==1.0.0
7. signedjson==1.0.0
8. pymacaroons-pynacl==0.9.3
9. Twisted==17.9.0
10. pyOpenSSL==17.3.0
11. pyasn1==0.1.7
12.pyasn1-modules==0.1.4
13. bcrypt==3.1.3
14. msgpack-python==0.4.8
And some other packages are also installed in VM

HomeServer version 0.23.0 and 0.23.1 i had checked both version same issue happened

When i execute Configuring synapse cmd

 python -m synapse.app.homeserver \
--server-name mydomainname \
--config-path homeserver.yaml \
--generate-config \
--report-stats=yes

I am constantly getting the following error

ERROR:root:Can't import 'msgpack' which is part of 'msgpack-python>=0.3.0'
Traceback (most recent call last):
  File "/home/ec2-user/.synapse/local/lib/python2.7/dist-packages/synapse/python_dependencies.py", line 107, in check_requirements
    module = __import__(module_name)
ImportError: No module named msgpack
Missing Requirement: Can't import 'msgpack' which is part of 'msgpack-python>=0.3.0'
To install run:
    pip install --upgrade --force "msgpack-python>=0.3.0"

Even after installing all the packages in my system.

I tried it by removing the entries one by one in python_dependencies.py But still I am getting error other than the one I have removed. My sense says that it could be some config / env setting.

Could anyone please guide me on that.

Thanks & Regards,
