# Summary: Run an executable with the selected Python version
|
|
#
|
|
# Usage: pyenv exec [-E|--environment] <command> [arg1 arg2...]
|
|
#
|
|
# -E Modify Python runtime environment, such as $PYTHONHOME, for the called executable.
|
|
#
|
|
# Runs an executable by first preparing PATH so that the selected Python
|
|
# version's `bin' directory is at the front.
|
|
#
|
|
# For example, if the currently selected Python version is 2.7.6:
|
|
# pyenv exec pip install -r requirements.txt
|
|
#
|
|
# is equivalent to:
|
|
# PATH="$PYENV_ROOT/versions/2.7.6/bin:$PATH" pip install -r requirements.txt
