# This command ensures that any previous installations of the same package
# are uninstalled.
# Note: "sage-pip-uninstall" is meant to be run after $(PYTHON) has
# been installed (either as an spkg or as a venv over a system python3).
# It is then guaranteed by sage-env that PATH is set in a way that "python3"
# refers to the correct python3.
PYTHON=python3
# The PIP variable is only used to determine the name of the lock file.
PIP=pip3
# We should avoid running pip while uninstalling a package because that
# is prone to race conditions. Therefore, we use a lockfile while
# running pip. This is implemented in the Python script sage-flock
LOCK="$SAGE_VENV/var/lock/$PIP.lock"
# --disable-pip-version-check: Don't periodically check PyPI to determine whether a new version of pip is available
# --no-input: Disable prompting for input.
# --yes: Don't ask for confirmation of uninstall deletions
# See sage-pip-install for a discussion of the other flags.
sage-flock -x $LOCK $PYTHON -m pip uninstall --isolated --disable-pip-version-check --yes --no-input "$@"
