【问题描述】：

我正在使用https://courses.cognitiveclass.ai/ 练习 Docker，并尝试运行具有以下内容的Dockerfile。

FROM python:3.6.1-alpine
RUN pip install flask
CMD ["python","app.py"]
COPY app.py /app.py

我用来运行的命令Dockerfile

sudo docker image build -t python-hello-world .

当我执行此操作时，它只完成了 1/5 步，而 2/5 步失败并出现以下错误。

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-dlih6aks/MarkupSafe/
You are using pip version 9.0.1, however version 21.2.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
The command '/bin/sh -c pip install flask' returned a non-zero code: 1

我需要对Dockerfile 进行任何更改吗？
