我是 Dockers 的新手，我正在嘗試使用以下方法對 Django 應用程式進行 dockerize：
FROM python:3.10.4-alpine3.15
ENV PYTHONUNBUFFERED=1
WORKDIR /app
RUN apk update \
&& apk add --no-cache gcc musl-dev postgresql-dev python3-dev libffi-dev \
&& pip install --upgrade pip
COPY ./requirements.txt ./
RUN pip install -r requirements.txt
COPY ./ ./
CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"]
但是當我運行時，docker build -t sometag .我收到以下錯誤：
ERROR [3/6] RUN apk update && apk add --no-cache gcc musl-dev postgresql-dev python3-dev libffi-dev && pip install --upgrade pip 10.5s

uj5u.com熱心網友回復：
好吧，很明顯你的 bash 命令失敗了。
注意縮進，這在 bash 命令中非常重要。
RUN apk update \
&& apk add --no-cache gcc musl-dev postgresql-dev python3-dev libffi-dev \
&& pip install --upgrade pip
如果不是那樣，那就是你的庫之一。
