Creating virtualenv skillsnetwork-nDNUhJi3-py3.14 in /home/ubuntu/.cache/pypoetry/virtualenvs

The current project's supported Python range (>=3.9,<4.0) is not compatible with some of the required packages Python requirement:
  - jupyterlite requires Python >=3.10, so it will not be installable for Python >=3.9,<3.10

Because skillsnetwork depends on jupyterlite (0.8.3) which requires Python >=3.10, version solving failed.

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

    For jupyterlite, a possible solution would be to set the `python` property to ">=3.10,<4.0"
