Fresh installation result in prompt-toolkit ImportError

[mmciver]

This is blocking me, and I haven't been able to find a reference to this elsewhere, or a solution. I suspect a version conflict, but even completely cleaning and reinstalling produces the same error every time.
File "/usr/lib/python3/dist-packages/awsshell/app.py", line 13, in <module> from prompt_toolkit.shortcuts import create_eventloop ImportError: cannot import name 'create_eventloop' from 'prompt_toolkit.shortcuts' (/usr/lib/python3/dist-packages/prompt_toolkit/shortcuts/__init__.py)

Even digging into the current versions of both aws-shell and prompt-toolkit, there appears to be a wildcard import in the past for the shortcuts/init.py, which was changed to an explicit list, and it no longer includes the create_eventloop that the awsshell/app.py is looking for.

Further puzzling is that on my prior system (Ubuntu 16.10) prompt-toolkit isn't even installed, and aws-shell works perfectly. Removing prompt-toolkit from the current system only moves the error to looking for it.

Possibly relevant system and versions:
Pop_OS 20.10

 $ aws --version
aws-cli/2.0.45 Python/3.7.3 Linux/5.8.0-7625-generic exe/x86_64.pop.20

(note, this was all also failing identically with aws-cli/1.18.170 Python/3.8.6 Linux/5.8.0-7625-generic botocore/1.19.10)

[amit-tewari-gelatoab]

https://stackoverflow.com/a/52019820 worked for me.

[EtricKombat-zz]

Using ubuntu 18.04 , getting the listed error . The above mentioned steps has been tried out but still not working.

[lewis-matthews-uk]

Also same issue for me in Ubuntu 20.04. Tried all the solutions suggested in stack overflow link, but not worked.

[EtricKombat-zz]

Can perform CLI tasking using CloudShell going forward ... (just an update)

[Dark-Alex-17]

I've managed to get it to work on Ubuntu 20.04 by uninstalling, and reinstalling from scratch with

pip install aws-shell --user

or

sudo pip install aws-shell --user

If you use the latter method, you might have to update your path to also include /root/.local/bin since that's where the scripts are installed.
