Note: httptools 0.0.13 from PyPI is incompatible with Python 3.9

[malthejorgensen]

Installing httptools v0.0.13 on Python 3.9 from PyPI (e.g. pip install httptools==0.0.13) doesn't work.

The relevant error output is this:

httptools/parser/parser.c:8977:52: error: no member named 'tp_print' in 'struct _typeobject'
  __pyx_type_9httptools_6parser_6parser_HttpParser.tp_print = 0;
  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^
httptools/parser/parser.c:8988:59: error: no member named 'tp_print' in 'struct _typeobject'
  __pyx_type_9httptools_6parser_6parser_HttpRequestParser.tp_print = 0;
  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^

  __pyx_type_9httptools_6parser_6parser_URL.tp_print = 0;

Since released PyPI package versions are immutable this cannot be fixed.

You can simply use httptools v0.1.0 instead. If this for some odd reason isn't possible for you, you can regenarate parser.c from parser.pyx using Cython version 0.29.14 or later and then install.

This isn't a bug report. Just an observation for later users, posted here for posterity. Closing immediately.
