postCreateCommand from devcontainer.json failed with /bin/sh: 1: source: not found

[s3bc40]

At the end of the devcontainer configuration I get:

Using CPython 3.13.0
Creating virtual environment at: .venv
Activate with: source .venv/bin/activate
/bin/sh: 1: source: not found
[5871 ms] postCreateCommand from devcontainer.json failed with exit code 127. Skipping any further user-provided commands.
Done. Press any key to close the terminal.

It seems that "postCreateCommand": "uv venv && source .venv/bin/activate && uv sync --all-extras" is the origin of this error /bin/sh: 1: source: not found.

Consequences:

• uv sync --all-extras is never reached and we have to do it afterwards

I have a commit in my fork that solve the issue and install everything -> 7d91df1

"postCreateCommand": "zsh -c 'uv venv && source .venv/bin/activate && uv sync --all-extras'"
