shiv is a command line utility for building fully self-contained Python zipapps as outlined in PEP 441, but with all their dependencies included!

shiv's primary goal is making distributing Python applications fast & easy.

Full documentation can be found here.

sys requirements

• python3.6+
• linux/osx/windows

how to

shiv has a few command line options of its own and accepts almost all options passable to pip install.

simple cli example

Creating an executable of pipenv with shiv:

$ shiv -c pipenv -o ~/bin/pipenv pipenv pew
$ ~/bin/pipenv --version
pipenv, version 2018.05.18

complex example involving a wheel cache

Creating an interactive executable with a downloaded wheel of boto:

$ python3 -m pip download boto
Collecting boto
  File was already downloaded /tmp/tmp.iklsO1qyd3/boto-2.48.0-py2.py3-none-any.whl
Successfully downloaded boto
$ shiv -o boto.pyz --find-links . --no-index boto
 shiv! 🔪
Collecting boto
Installing collected packages: boto
Successfully installed boto-2.48.0
 done
$ ./boto.pyz
Python 3.6.1 (default, Apr 19 2017, 21:58:41)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-4)] on linux

installing

You can install shiv via pip / pypi

pip install shiv

You can even create a pyz of shiv using shiv!

python3 -m venv .
source bin/activate
pip install shiv
shiv -c shiv -o shiv shiv

developing

We'd love contributions! Getting bootstrapped to develop is easy:

git clone [e-mail]:linkedin/shiv.git
cd shiv
python3 setup.py venv
. activate
python3 setup.py develop

Don't forget to run and write tests:

pip install tox
tox

gotchas

Zipapps created with shiv are not guaranteed to be cross-compatible with other architectures. For example, a pyz file built on a Mac may only work on other Macs, likewise for RHEL, etc. This usually only applies to zipapps that have C extensions in their dependencies. If all your dependencies are pure python, then chances are the pyz will work on other platforms. Just something to be aware of.

Zipapps created with shiv will extract themselves into ~/.shiv, unless overridden via SHIV_ROOT. If you create many utilities with shiv, you may want to occasionally clean this directory.
