Cannot install gino with fastapi

[Pzzzzz5142]

Describe the bug Hi, when following the guide on the official website, poetry raise an error reporting that it can't resolve the dependencies.

To Reproduce Just type in the following command to reproduce.

poetry add gino[pg,starlette]

poetry add fastapi uvicorn gunicorn

Expected result

Successfully installed all the packages 

Actual result

  SolverProblemError

  Because no versions of fastapi match >0.65.1,<0.66.0
   and fastapi (0.65.1) depends on starlette (0.14.2), fastapi (>=0.65.1,<0.66.0) requires starlette (0.14.2).
  Because gino-starlette (0.1.1) depends on starlette (>=0.13.0,<0.14.0)
   and no versions of gino-starlette match >0.1.1,<0.2.0, gino-starlette (>=0.1.1,<0.2.0) requires starlette (>=0.13.0,<0.14.0).
  Thus, fastapi (>=0.65.1,<0.66.0) is incompatible with gino-starlette (>=0.1.1,<0.2.0).
  And because gino (1.0.1) depends on gino-starlette (>=0.1.1,<0.2.0)
   and no versions of gino match >1.0.1,<2.0.0, fastapi (>=0.65.1,<0.66.0) is incompatible with gino (>=1.0.1,<2.0.0).
  So, because wjx depends on both gino (^1.0.1) and fastapi (^0.65.1), version solving failed.

This belongs to gino-starlette and is in fact already an issue there.

Not exactly related but if you are using zsh and getting zsh: no matches found: gino[pg,starlette] Use quote (eg: poetry add 'gino[pg,starlette]') as zsh doesn't recognise corner brackets as commands
