我試圖為我的 django 專案運行我的 docker 映像，但出現錯誤：

我嘗試使用不同版本的python，但總是出現同樣的問題！
這是我的 docker 檔案
FROM python:3
RUN pip install --upgrade pip
ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
COPY . /code/
RUN pip install -r requairements.txt
EXPOSE 8000
CMD ["gunicorn", "--chdir", "Eventful-main", "--bind", ":8000", "eventful.wsgi:application"]

10

if len(list(version_info)) != 3:
