Pipfile cannot be locked currently

[aflueckiger]

Pipenv cannot be locked currently due to a dependency conflict. The issue boils down to a dependency on an obsolete version boto3 coming from impresso-commons. The boto3 package needs to be pinned to a more recent version in the impresso-commons package.

[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.
