To solve this error only add the pytest-runner dependency in the command

RUN apk add --update \
  tzdata \
  python \
  py-pip \
  ca-certificates \
  && pip install pytest-runner \
  && pip install --no-cache-dir --disable-pip-version-check flexget==2.21.2 transmissionrpc==0.11 \
  && rm -rf /var/cache/apk/*
