dmenv: simple and practical virtualenv manager for Python

Overview

dmenv handles creation of virtualenv and lock files for you.

Here it is in action:

• First, generate a requirements.lock to "freeze" all your dependencies

bash $ dmenv lock Creating virtualenv in: /path/to/.venv/3.6.7 -> running /usr/bin/python3 -m /path/to/.venv venv/3.6.7 -> running /path/to/.venv/3.6.7/bin/python -m pip install pip --upgrade ... -> running /path/to/.venv/3.6.7/bin/pip freeze --exclude-editable :: Requirements written to /path/to/requirements.lock

• Then, anyone can use the requirements.lock to install all the dependencies at their frozen version:

bash $ dmenv install :: Creating virtualenv in: /path/to/.venv/3.6.7 -> running /usr/bin/python3 -m venv /path/to/.venv/3.6.7 -> running /path/to/.venv/3.6.7/bin/python -m pip install pip --upgrade ... -> running /path/to/.venv/3.6.7/bin/python setup.py develop --no-deps ... Installing demo script to /path/to/.venv/3.6.7/bin
