aws-shell is not working in Amazon Linux 2 after installing

Hi, Im getting the following error after installing aws-shell in my EC2 Amazon Linux 2:

[ec2-user@tmp]$ aws-shell First run, creating autocomplete index... Traceback (most recent call last): File "/home/ec2-user/.local/bin/aws-shell", line 8, in sys.exit(main()) File "/home/ec2-user/.local/lib/python2.7/site-packages/awsshell/init.py", line 47, in main write_index(index_file) File "/home/ec2-user/.local/lib/python2.7/site-packages/awsshell/makeindex.py", line 69, in write_index result = json.dumps(index) File "/usr/lib64/python2.7/json/init.py", line 244, in dumps return _default_encoder.encode(obj) File "/usr/lib64/python2.7/json/encoder.py", line 207, in encode chunks = self.iterencode(o, _one_shot=True) File "/usr/lib64/python2.7/json/encoder.py", line 270, in iterencode return _iterencode(o, 0) MemoryError

Are you able to help ?
