pip (original) (raw)

@pradyunsg @nlhkabu

Pradyun asked for input on this as it was blocking him. Looking back to Nicole's original message suggestion, we should implement that message, but include some spacing as follows:

Installing collected packages: pycodestyle, flake8-import-order, pyflakes, mccabe, flake8 Warning: 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. Warning: Pip will install or upgrade your package(s) and its dependencies without taking into account other packages you already have installed. This may cause an uncaught dependency conflict. If you would like pip to take your other packages into account, please tell us here: https://forms.gle/cWKMoDs8sUVE29hz9 flake8 3.5.0 requires mccabe<0.7.0,>=0.6.0, but you'll have mccabe 0.5.3 which is incompatible. flake8 3.5.0 requires pycodestyle<2.4.0,>=2.0.0, but you'll have pycodestyle 2.6.0 which is incompatible. Successfully installed flake8-3.5.0 flake8-import-order-0.17.1 mccabe-0.5.3 pycodestyle-2.6.0 pyflakes-1.6.0

The spacing is to improve the formatting of this output text - otherwise the important message explaining 1) pip behaviour is changing, 2) recommendation on ways to minimise impact of the changes, 3) request for user input on what future pip behaviour should be, are lost in this blob of text.

Pradyun is concerned the message (from Warning: After October 2020....to....please tell us here: LINK) is too long and will annoy users once it's been shown once, so I'm suggesting this part of the message:

Warning: 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.

Warning: Pip will install or upgrade your package(s) and its dependencies without taking into account other packages you already have installed. This may cause an uncaught dependency conflict.

would be shown for only 48 hours, after which it would be hidden. This approach was suggested by @dstufft and @pfmoore in another ticket.

@dstufft @pfmoore is there a recommended approach/reusable code to implement hiding the message portion?
