Hi there, I did:

• Clone the repo
• Run pip install "git+https://github.com/deepset-ai/haystack.git#egg=rest_api&subdirectory=rest_api"
• Run gunicorn rest_api.application:app -b 0.0.0.0:8000 -k uvicorn.workers.UvicornWorker -t 300
• Then faced this error:

Opps, I run pip install -e '.[dev]' and everything ok :))

I am also facing a similar issue, However in my case it is not getting fixed by using this command.

Can you help me with some additional information, like on which directory should I use this command and something of sorts.
