# Special case pip and setuptools to generate versioned wrappers
|
||
|
|
#
|
||
|
|
# The issue is that some projects (specifically, pip and setuptools) use
|
||
|
|
# code in setup.py to create "versioned" entry points - pip2.7 on Python
|
||
|
|
# 2.7, pip3.3 on Python 3.3, etc. But these entry points are baked into
|
||
|
|
# the wheel metadata at build time, and so if the wheel is installed with
|
||
|
|
# a *different* version of Python the entry points will be wrong. The
|
||
|
|
# correct fix for this is to enhance the metadata to be able to describe
|
||
|
|
# such versioned entry points, but that won't happen till Metadata 2.0 is
|
||
|
|
# available.
|
||
|
|
# In the meantime, projects using versioned entry points will either have
|
||
|
|
# incorrect versioned entry points, or they will not be able to distribute
|
||
|
|
# "universal" wheels (i.e., they will need a wheel per Python version).
|
||
|
|
#
|
||
|
|
# Because setuptools and pip are bundled with _ensurepip and virtualenv,
|
||
|
|
# we need to use universal wheels. So, as a stopgap until Metadata 2.0, we
|
||
|
|
# override the versioned entry points in the wheel and generate the
|
||
|
|
# correct ones. This code is purely a short-term measure until Metadata 2.0
|
||
|
|
# is available.
|
||
|
|
#
|
||
