Subject: [PATCH] 00251: Change user install location
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Set values of prefix and exec_prefix in distutils install command
to /usr/local if executable is /usr/bin/python* and RPM build
is not detected to make pip and distutils install into separate location.
Fedora Change: https://fedoraproject.org/wiki/Changes/Making_sudo_pip_safe
Downstream only: Reworked in Fedora 36+/Python 3.10+ to follow https://bugs.python.org/issue43976
pypa/distutils integration: https://github.com/pypa/distutils/pull/70
Also set sysconfig._PIP_USE_SYSCONFIG = False, to force pip-upgraded-pip
to respect this patched distutils install command.
See https://bugzilla.redhat.com/show_bug.cgi?id=2014513
