Pillow is not found by Django thouhg it is installed using docker

Hello I am following this tutorial tutorial link. Everything is working fine but when i run bellow command it says pillow is not found but pillow already is installed.

docker-compose -f docker-compose.prod.yml exec app python manage.py migrate --noinput

This is the error:

employee.Employee.image: (fields.E210) Cannot use ImageField because Pillow is not installed.
    HINT: Get Pillow at https://pypi.org/project/Pillow/ or run command "python -m pip install Pillow".
students.Student.image: (fields.E210) Cannot use ImageField because Pillow is not installed.
    HINT: Get Pillow at https://pypi.org/project/Pillow/ or run command "python -m pip install Pillow".

Then i again try to install using bellow command

docker-compose -f docker-compose.prod.yml exec app python -m pip install Pillow

And it says pillow is Pillow is already installed

Requirement already satisfied: Pillow in /usr/local/lib/python3.8/site-packages (6.2.1)

Here is my docker file

I was stuck with the same problem. Adding these dependencies to the FINAL section resolved this issue

# install pillow dependencies
RUN apk add --no-cache jpeg-dev zlib-dev \
    fribidi-dev \
    harfbuzz-dev \
    lcms2-dev \
    openjpeg-dev \
    tcl-dev \
    tiff-dev \
    tk-dev

Add this two lines under the FINAL section, just below the RUN apk update && apk add libpq

# install pillow dependencies
RUN apk add --no-cache jpeg-dev zlib-dev
RUN apk add --no-cache --virtual .build-deps build-base linux-headers

This is happening because the BUILDER removes the dependencies required for Pillow after creating the image. In the FINAL image, Pillow is available, but its required dependencies are not.

Please try to use "pillow" starting from lowercase p.
