I have

• Python 3.11
• poetry 1.7.1

When I do the command

poetry show --outdated

it shows me a list of libraries outdates, also myPy:

but when I do

poetry update mypy

nothing happens, output is:

 Updating dependencies
 Resolving dependencies... (0.3s)
 No dependencies to install or update

And this is my pyproject.toml

[tool.poetry.dev-dependencies]
black = "~24.1.1"
flake8 = "~7.0.0"
isort = "~5.13.2"
mypy = "~1.8.0"

I’ve changed this mypy = “~1.8.0” into mypy = “~1.8”
following this guide:

Tilde requirements Python Poetry

but nothing has changed.

What I am missing ?
