List all Brightway Dependencies

[michaelweinold]

Adding new packages to a Pyodide kernel involves:

(JupyterLite) "Use additional Python packages" (Pyodide) "Loading packages"

For instance,

%pip install -q bw2io

throws the error

ValueError: Can't find a pure Python 3 wheel for 'psutil'.
See: https://pyodide.org/en/stable/usage/faq.html#micropip-can-t-find-a-pure-python-wheel
You can use `micropip.install(..., keep_going=True)`to get a list of all packages with missing wheels.

This was briefly discussed in 2022 with the Pyodide team in https://github.com/pyodide/pyodide/issues/3056:

psutil won't be very useful on Pyodide. Emscripten platform does not support any process, resource, signals, or similar POSIX APIs. Browsers are also sandboxed. You won't be able to see or modify any processes on the host system.

A complete list of all dependencies of the Brightway ecosystem must therefore be compiled.

Tasks

• [x] list all requirements of bw2io (and their pyodide/emscripten-forge status)
• [x] list all requirements of bw2data (and their pyodide/emscripten-forge status)
• [x] list all requirements of bw2calc (and their pyodide/emscripten-forge status)
• [x] list all requirements of bw2analyzer (and their pyodide/emscripten-forge status)
