venv-pack2 0.5.0

Package virtual environments for redistribution

Venv-Pack

This is based on venv-pack but with lots of improvements added by mrmathematica. It has Windows support. Bin/Scripts generated by venv will work without out-of-box.

Venv-pack is a command-line tool for packaging virtual environments for distribution. This is useful for deploying code in a consistent environment.

Supports virtual environments created using python3/venv. Venv is part of the python standard library.

Install from source

venv-pack is available on github and can always be installed from source.

pip install git+https://github.com/mrmathematica/venv-pack.git

Command-line Usage

One common use case is packing an environment on one machine to distribute to other machines as part of a deployment process.

On the source machine

Create venv, and then upgrade pip + setuptools first:

python -m venv venv
venv\Scripts\activate
python -m pip install -U pip setuptools

Python generates Windows .exe file such as pip.exe on the fly, so on Windows there is restriction that you want to fix a version of pip and setuptools at the beginning and stick with it. If needed, re-create new venv from a lock file. See pip-tools.

Install all your python packages, for example

pip install -r requirements.txt

Pack the current environment into my_env.zip

venv-pack -o env.zip

Pack an environment located at an explicit path into my_env.zip

venv-pack -p explicit\path\to\env -o env.zip 

On the target machine

Unpack environment into directory my_env

md my_env
python -m zipfile -e venv.zip my_env\ 

All features of venv should keep working from my_env folder.
