pyenv-do is a pyenv plugin that provides a pyenv do command to exeute command installed in pyenv-managed Python. This is the improvement of original pyenv exec command. (See also issue #1932)

Installing pyenv-do as a pyenv plugin will give you access to the pyenv do command.

$ git clone https://github.com/kotokaze/pyenv-do.git $(pyenv root)/plugins/pyenv-do

To execute in a specific version, just start with pyenv do --env <version>.

$ pyenv do --env 3.8.13 python --version

Or, you can use instead of the pyenv exec command (current version will be used).

$ pyenv do pip install -r requirements.txt
