Pip installs Plock. Plock installs Plone.

Project description


“Pip installs Plock. Plock installs Plone.”

—Alex Clark

Plock installs Plone for experimentation purposes only. This is not your production Plone.


pip install plock && plock `tmp`


Setuptools errors?

Plock only supports the latest version of setuptools. If you’re setuptools is older than the latest version, update it. You can update setuptools via:

wget -O - | python

See: for more installation instructions.

Missing requirements?

Plock only supports installation of Plone’s Python requirements. To satisfy your operating system’s requirements e.g. Ubuntu, please see:

Why use pip?

Python web developers who use popular Python web frameworks (e.g. Django, Pyramid, Flask) are generally more familiar with pip than Buildout.

Why build Plock on top of Buildout?

Plock is a workaround for pip install Plone which technically works but requires a lengthy requirements.txt file and is missing features provided by Buildout e.g. Zope2 instance creation.

Why the name Plock?

Plock is a single by the band Plone. It is also the name of a city in Poland.

Plone version?

Plock only supports the latest version of Plone, but with Plock Pins you can run any version by editing the extends parameter in the buildout section in buildout.cfg.
