  ╰─▶ Because asyncache==0.3.1 depends on cachetools>=5.2.0,<6.0.0 and nanapi
      depends on asyncache==0.3.1, we can conclude that nanapi depends on
      cachetools>=5.2.0,<6.0.0.
      And because nanapi depends on cachetools==6.2.4 and your workspace
      requires nanapi, we can conclude that your workspace's requirements
      are unsatisfiable.
