I'm trying to write the Dockerfile for a small python web project and there is something wrong with the dependencies. I've been doing some search on the internet and it said that Librosa library requires libsndfile to work properly so I tried to install it using apt-get install libsndfile1 (I've also tried libsndfile-dev,...) . However, it doesn't seem to solve my problem.
This is how my Dockerfile looks like:
FROM python:3.6-buster as buildENV STATIC_URL /static
ENV STATIC_PATH /var/www/app/staticWORKDIR /var/www/RUN python -m venv /opt/venvENV PATH="/opt/venv/bin:$PATH"COPY requirements.txt .RUN pip install -r requirements.txtRUN pip install gunicornRUN apt-get update -y && apt-get install -y --no-install-recommends build-essential gcc \libsndfile1 FROM python:3.6-buster AS runCOPY --from=build /opt/venv /opt/venvCOPY . .ENV PATH="/opt/venv/bin:$PATH"RUN gunicorn -b :5000 --access-logfile - --error-logfile - app:app
However, when i try to build and run this, this error occured:
