pip

A common problem with Python development for large-scale teams is sharing internal libraries. At Vendasta we’ve been solving this problem using a private PyPI installation running on Google App Engine with Python eggs and wheels being served by Google Cloud Storage. Today, we are announcing the open source version of this tool — CloudPyPI. CloudPyPI is a modification of pypiserver for running on Google App Engine. We’ve also introduced a simple user management system to allow authenticated access to your Python packages....

At Vendasta we’ve been slowly adopting pypi and pip for our internal code libraries and the time has come to deploy our own private pypi server. After evaluating a few options I settled on the simplistic pypiserver – a barebones implementation of the simple HTTP API to pypi. The deployment uses nginx as a front-end to pypiserver. pypiserver itself is ran and monitored using supervisord. I created a bash script that creates a user and group to run pypiserver and installs and runs nginx, supervisord and pypiserver....

One unfortunate difficulty when working with App Engine is managing your local dependencies. You don’t have access to your Python environment so all libraries you wish to use must be vendored with your installation. That is, you need to copy all of your library code into a local folder to ship along with your app. ...

I recently tried installing lxml for use within an App Engine project on OS X Mavericks only to be hit with an error message from clang. ...
