The conflict is caused by:
The user requested starlette==0.13.8
fastapi 0.61.1 depends on starlette==0.13.6
To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict
:stderr: ERROR: Cannot install fastapi==0.61.1 and starlette==0.13.8 because these package versions have conflicting dependencies.
