## `pyenv exec`
`Usage: pyenv exec <command> [arg1 arg2...]`
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 3.9.7:
`pyenv exec pip install -r requirements.txt`
is equivalent to:
`PATH="$PYENV_ROOT/versions/3.9.7/bin:$PATH" pip install -r requirements.txt`
## `pyenv root` ## `pyenv root`
Displays the root directory where versions and shims are kept. Displays the root directory where versions and shims are kept.
