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

$ 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:

$ 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
