The "poetry.dev-dependencies" section is deprecated and will be removed in a future version. Use "poetry.group.dev.dependencies" instead.

The current project's supported Python range (>=3.8,<3.11) is not compatible with some of the required packages Python requirement:
  - alembic requires Python >=3.10, so it will not be installable for Python >=3.8,<3.10
  - alembic requires Python >=3.10, so it will not be installable for Python >=3.8,<3.10
  - alembic requires Python >=3.10, so it will not be installable for Python >=3.8,<3.10
  - alembic requires Python >=3.10, so it will not be installable for Python >=3.8,<3.10
  - alembic requires Python >=3.10, so it will not be installable for Python >=3.8,<3.10

Because no versions of alembic match >1.18.0,<1.18.1 || >1.18.1,<1.18.2 || >1.18.2,<1.18.3 || >1.18.3,<1.18.4 || >1.18.4,<1.19.0
 and alembic (1.18.0) requires Python >=3.10, alembic is forbidden.
And because alembic (1.18.1) requires Python >=3.10, alembic is forbidden.
And because alembic (1.18.2) requires Python >=3.10
 and alembic (1.18.3) requires Python >=3.10, alembic is forbidden.
So, because alembic (1.18.4) requires Python >=3.10
 and todo-bot depends on alembic (~1.18.0), version solving failed.

  * Check your dependencies Python requirement: The Python requirement can be specified via the `python` or `markers` properties

    For alembic, a possible solution would be to set the `python` property to ">=3.10,<3.11"
