How to install and upgrade Datasette using pipx (via) I’ve been using pipx to run Datasette for a while now—it’s a neat Python packaging tool which installs a Python CLI command with all of its dependencies in its own isolated virtual environment. Today, thanks to Twitter, I figured out how to install and upgrade plugins in the same environment—so I added a section to the Datasette installation documentation about it. # 4th May 2020, 7:23 pm

What to do when PyPI goes down. My deployment scripts tend to rely on PyPI these days (they install dependencies in to a virtualenv) which makes me distinctly uncomfortable. Jacob explains how to use the PyPI mirrors that are starting to come online, but that won’t help if the PyPI listing links to an externally hosted file which starts to 404, as happened with the python-openid package quite recently (now fixed). The comments on the post discuss workarounds, including hosting your own PyPI mirror or bundling tar.gz files of your dependencies with your project. # 21st July 2010, 10:19 am

Tools of the Modern Python Hacker: Virtualenv, Fabric and Pip. Ashamed to say I’m not using any of these yet—for Django projects, my manage.py inserts an “ext” directory at the beginning of the Python path which contains my dependencies for that project. # 9th July 2009, 11:40 am
