devcontainer fails to run postscript

[nzolman]

Received the following with a fresh VS Code devcontainer on a new machine.

Running the postCreateCommand from devcontainer.json...

[1554250 ms] Start: Run in container: /bin/sh -c source /home/firedrake/firedrake/bin/activate && pip install -e .
/bin/sh: 1: source: not found
[1554352 ms] postCreateCommand failed with exit code 127. Skipping any further user-provided commands.

I think this is related to this issue for running source in Docker containers.

The container otherwise builds fine, so it seems plausible to build everything from scratch in terminal afterwards. However, because the python venv is not successfully activated, it doesn't install hydrogym and both python and pip will point to the wrong python inside the container. When I manually source activate ... and pip install ., I get the following:

This implies that there are a number of dependencies that are not accounted for during the pip installation. After manually installing, I can import hydrogym, etc.
