+**Looks like you're trying to use a Poetry command that is not available.**
+
+Since Poetry (2.0.0), the shell command is not installed by default. You can use,
+
+  - the new env activate command (recommended); or
+  - the shell plugin to install the shell command
+
+Documentation: https://python-poetry.org/docs/managing-environments/#activating-the-environment
+
+Note that the env activate command is not a direct replacement for shell command.
