How do I get the list of all the versions of a package?

choco list -e <package> -a

-e, --exact

Only return packages with this exact name.

choco list --by-id-only [package] -a

--by-id-only

Only return packages where the id contains the search filter.

You just need to add the --all to the end of your request. You can also add -v for verbose output.

Choco list packagename --all
