I'm trying to build a Docker container in which I want to install some Python modules using pip (these modules will eventually be needed to build an app). I have written the following Dockerfile:
FROM ubuntu:16.04
RUN echo "===> Adding prerequisites..." && \
apt update -y && \
DEBIAN_FRONTEND=noninteractive \
apt install --no-install-recommends -y -q \
build-essential \
python python-pip python-dev && \
pip install --upgrade setuptools pip wheel && \
pip install --upgrade pyyaml
# Default command
CMD [ "echo", "Hello!" ]
I get the following output when building (docker build -t app:0 .):
Sending build context to Docker daemon 10.26MB
Step 1/3 : FROM ubuntu:16.04
---> 4a689991aa24
Step 2/3 : RUN echo "===> Adding prerequisites..." && apt update -y && DEBIAN_FRONTEND=noninteractive apt install --no-install-recommends -y -q build-essential python python-pip python-dev && pip install --upgrade setuptools pip wheel && pip install --upgrade pyyaml

However, if I remove the second call to pip from the Dockerfile, it appears the container is built successfully.
Can anyone please help me understand what is triggering the build error? Many thanks in advance!
This appears to be an issue when upgrading pip as you can see here:
https://github.com/pypa/pip/issues/5240
Instead of running
pip install --upgrade setuptools pip wheel
try altering to
python -m pip install --upgrade setuptools pip wheel
as suggested:
The docker image will then be built without errors.
