The command returned a non-zero code: 2 docker

The following is the Dockerfile,

FROM alpine:3.10

# Add the testing repo in case it's needed for additional dependencies
# For example, gdal can be installed by using gdal@community
RUN echo "@community http://dl-cdn.alpinelinux.org/alpine/edge/community" >> /etc/apk/repositories

# Install system dependencies
RUN apk add --no-cache --update \
  bash \
  gcc \
  build-base \
  musl-dev \
  postgresql-dev \
  'python3~=3.7.5' \
  'python3-dev~=3.7.5' \
  curl \
# zlib, zlib-dev, and libjpeg-turbo are required by pillow
  zlib \
  zlib-dev \
  libjpeg-turbo \
  libjpeg-turbo-dev \
  libffi-dev
RUN pip3 install --no-cache-dir -q pipenv

# Add our code
ADD ./ /opt/webapp/
WORKDIR /opt/webapp

# Install dependencies
RUN pipenv install --deploy --system

# Allow SECRET_KEY to be passed via arg so collectstatic can run during build time
ARG SECRET_KEY
RUN python3 manage.py collectstatic --no-input

# Run the image as a non-root user
RUN adduser -D myuser
USER myuser

# Run the web server on port $PORT
CMD waitress-serve --port=$PORT performit_15391.wsgi:application

The following is the LOG from the server that is recorded, I don't know why the build is failing, can anybody guide please?

This above is the log, the apk command is failing. Is there any dependency issue? for me the log message isn't very much useful. Thanks in advance.

There is a version conflict while installing Python. APK package manager supports python-3.7.7-r0 for alpine:3.10. But you have explicitly mentioned version 3.7.5 which is not available. Here either you can go with python 3.7.7 or use a base image which has python 3.7.5 to build your app.
