Subject: [Attn: mercurial maintainer] hg fails with python3.9
Date: Thu, 28 Apr 2022 10:27:17 -0400 [thread overview]
Message-ID: <257359ee-9899-47c9-a158-fb79ef4890a3@cornell.edu> (raw)
/usr/bin/hg specifies /usr/bin/python3 in its shebang, but further down it has
libdir = '../lib/python3.8/site-packages'
This causes hg to fail as follows if /usr/bin/python3 points to python3.9:
$ hg
