```console
$ fastapi dev main.py
```

But you would have to remember to pass the correct path every time you call the `fastapi` command.

Additionally, other tools might not be able to find it, for example the [VS Code Extension](../editor-support.md) or [FastAPI Cloud](https://fastapicloud.com), so it is recommended to use the `entrypoint` in `pyproject.toml`.

To disable the configuration cache, run the build with `--no-configuration-cache`.

Tasks known to have problems are listed in the build logic. You can find this list at:

If you discover a task that doesn't work with the configuration but it not in this list, please add it.
