When using AWS CLI v2: importlib.metadata.PackageNotFoundError: No package metadata was found for prompt_toolkit

[evanstucker-hates-2fa]

See aws/aws-cli#9453

I don't know if the root cause of this issue is on the aws-cli-v2 side or on the python-prompt_toolkit side, so I thought it would be good to raise it over here too.

Temporary workaround for people using Arch who still have the previous package cached - downgrade python-prompt_toolkit:

sudo pacman -U /var/cache/pacman/pkg/python-prompt_toolkit-3.0.50-1-any.pkg.tar.zst

Experiencing this as well (I do not use Arch btw).

For the fellow arch users, you can downgrade the package via:

git clone  https://gitlab.archlinux.org/archlinux/packaging/packages/python-prompt_toolkit.git
# cd to dir
git checkout 3.0.50-1
makepg
sudo pacman -U python-prompt_toolkit-3.0.50-1-any.pkg.tar.zst
