[macbre]

The current project's Python requirement (3.10.0a5) is not compatible with some of the required packages Python requirement:
    - dataclasses requires Python >=3.6, <3.7, so it will not be satisfied for Python 3.10.0a5
  
  Because no versions of black match >21.5b1,<22.0
   and black (21.5b1) depends on dataclasses (>=0.6), black (>=21.5b1,<22.0) requires dataclasses (>=0.6).
