I am trying to install prophet, yet (only when trying to docker build by image) the following error is thrown:

The above issue does not appear on my local execution. I have installed prophet using the pip install prophet command and everything works properly. The issue arises only when trying to create the Docker image.
The Dockerfile I use is the following:
FROM ubuntu:18.04
RUN apt-get update
# To avoid the questions related to the geographic area
RUN ln -snf /usr/share/zoneinfo/$CONTAINER_TIMEZONE /etc/localtime && echo $CONTAINER_TIMEZONE > /etc/timezone
RUN apt-get install -y python3.10 python3-pip
RUN pip3 install flask pandas numpy cython
RUN python3 -m pip install prophet
COPY app.py app.py
COPY checks.py checks.py
COPY predict.py predict.py
EXPOSE 5000
CMD ["python3", "-u", "app.py"]
I've tried also to install ujson and then try to install prophet. The ujson is installed yet afterwards the same issue arises.
The error because you're using an old version of the import of __future__ annotations as shown here https://peps.python.org/pep-0563/#enabling-the-future-behavior-in-python-3-7.
Since you're using Python10, try to upgrade pip, so your Dockerfile becomes:
FROM ubuntu:18.04
...
RUN apt-get install -y python3.10 python3-pip
RUN pip3 install --upgrade pip
RUN pip3 install flask pandas numpy cython prophet
...
