Title:

check_dependencies.check_requirements() Fails with Correct Dependencies in maturin-Built Package, Program Runs After Commenting It Out

Description:

I have successfully built and installed matrix-synapse from source using maturin, and all dependencies seem to be correctly installed and configured. However, when running the server, the check_dependencies.check_requirements() function fails, despite all the necessary dependencies being present in the environment.

After commenting out the check_dependencies.check_requirements() function, the program starts and runs without any issues.

Steps to Reproduce:

1. Build matrix-synapse from source using maturin:

   maturin develop

Have you executed poetry install first?
When I've seen people using maturin develop it's within the context of already having run poetry install first, which is our primary way of developing on the code.

As far as I know maturin develop is only favoured when changing the Rust code during development.
