docker 内的“Pip install -r /code/requirements.txt”引发错误

Question

所以，我在 docker 镜像中运行此命令：

pip install --no-cache-dir --upgrade -r /code/requirements.txt

它会引发以下警告，然后出现错误：

 > [5/7] RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt:

如果我在 docker 外部使用命令安装

requierments.txt

，所有库都已安装，但在 docker 内部会导致错误。

完整的 docker 文件：

FROM python:3.11

ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

WORKDIR /code/src

COPY ./requirements.txt /code/requirements.txt

RUN pip install --upgrade pip
RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt

COPY ./ /code/src
ENV PYTHONPATH /code/src

RUN chmod a+x run.sh
CMD ["./run.sh"]

我该怎么办？

Answer 1

connection broken by ReadTimeoutError("HTTPSConnectionPool(host='pypi.org', port=443): Read timed out. (read timeout=15)")

此错误表明这是服务器超时错误。 你可以尝试增加

timeout

:

RUN pip install --no-cache-dir --upgrade --default-timeout=100 -r  /code/requirements.txt
