From 0dd80709b5dc03756e7f4510761ae60236bb9f6d Mon Sep 17 00:00:00 2001 From: Ned Deily Date: Wed, 2 May 2018 01:30:33 -0400 Subject: bpo-33290: Have macOS installer remove "pip" alias (GH-6683) Currently, "pip3 install --upgrade pip" unconditionally installs a "pip" alias even for Python 3. If a user has an existing Python 3.x installed from a python.org macOS installer and then subsequently manually updates to a new version of pip, there may now be a stray "pip" alias in the Python 3.x framework bin directory which can cause confusion if the user has both a Python 2.7 and 3.x installed; if the Python 3.x fw bin directory appears early on $PATH, "pip" might invoke the pip3 for the Python 3.x rather than the pip for Python 2.7. To try to mitigate this, the macOS installer script for the ensurepip option will unconditionally remove "pip" from the 3.x framework bin directory being updated / installed. (The ambiguity can be avoided by using "pythonx.y -m pip".) --- Mac/BuildScript/scripts/postflight.ensurepip | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/Mac/BuildScript/scripts/postflight.ensurepip b/Mac/BuildScript/scripts/postflight.ensurepip index 3074fa3..36d0594 100755 --- a/Mac/BuildScript/scripts/postflight.ensurepip +++ b/Mac/BuildScript/scripts/postflight.ensurepip @@ -12,6 +12,11 @@ umask 022 "${FWK}/bin/python${PYVER}" -E -s -m ensurepip --upgrade +# bpo-33290: An earlier "pip3 install --upgrade pip" may have installed +# a "pip" in the fw bin directory.
