05/17/2022, 4:11 PMwhat version were you using before? this is probably the deprecation from "context-aware object factories" to target generators

05/17/2022, 4:15 PMk so in 2.10, it defaults to still using the old macros. 2.11 changes the default to stop using it. 2.12 entirely removes the old macros
so you need to handle that deprecation, ideally while you are on stable 2.10 first
you don't get a warning message in 2.10 w/ instructions? are you using
pants_ignore--no-pantsdf
fresh-cat-90827
05/17/2022, 4:18 PMhm, so in my dependencies,
"//:pymysql"python_requirementsmodule_mappingperhaps I just need to address the dependency with the right path
you don’t get a warning message in 2.10 w/ instructions? are you usingI did ignore those and have noticed now, thanks for this.?pants_ignore
so my problem is then how to address

05/17/2022, 4:49 PMso you will want to follow the instructions precisely on 2.10 and have
use_deprecated_python_macros = falsefollow the instructions preciselyThere are a few steps involved, unfortunately. And it's an "atomic change" - in-betwen states don't work. You have to do it all in one swoop
