It turns out that pip uses sre_constants in its copy of pyparsing. The problem is already fixed in the upstream of pyparsing and soon should be fixed in pip. We still need to keep sre_constants and maybe other sre_* modules, but deprecate them. > Could the sre_parse and sre_constants modules be kept with public names (i.e. > without the leading underscore) but within the re namespace? It is a good idea which will allow to minimize breakage in short term. You can write "from re import sre_parse", and it would work in old and new versions because sre_parse and sre_compile were imported in the re module. This trick does not work with sre_constants, you still need try/except. But the code that depends on these modules is fragile and can be broken by other ways. > Please don't merge too close to the 3.11 beta1 release date, I'll submit PRs > after this merged. I am going to implement step 2 only after merging your changes for issue23689. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue47152> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
