[pipenv.exceptions.ResolutionFailure]: Warning: Your dependencies could not be resolved. You
likely have a mismatch in your sub-dependencies.
First try clearing your dependency cache with $ pipenv lock --clear, then try the original
command again.
Alternatively, you can use $ pipenv install --skip-lock to bypass this mechanism, then run $
pipenv graph to inspect the situation.
Hint: try $ pipenv lock --pre if it is a pre-release dependency.
