Warnings when pip installing #8

Closed TheCleric closed 4 years ago

TheCleric commented 4 years ago

I just added poetry (latest, 1.0.10) and poethepoet (latest, 0.8.0) to a virtualenv, and after installing poethepoet I get the following message:

$ pip install poethepoet

    Uninstalling tomlkit-0.5.11:
      Successfully uninstalled tomlkit-0.5.11
ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts.

We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.

poetry 1.0.10 requires tomlkit<0.6.0,>=0.5.11, but you'll have tomlkit 0.7.0 which is incompatible.

Thanks for reporting this. Maybe dependencies specification could be loosened to avoid this sort of thing.

As it happens poetry specifies tomlkit = ">=0.7.0,<1.0.0" on master so this particular warning should go away on its own soon enough.
