Docker Build在PIP升级时崩溃，但是错误消息说升级PIP

Question

我正在尝试从以下（删节）docker文件构建图像：

FROM nvidia/cuda:8.0-cudnn6-devel-ubuntu16.04
LABEL maintainer [email protected]


RUN apt-get update && apt-get install -y --no-install-recommends \
        build-essential \
        cmake \
        git \
        wget \

ENV CAFFE_ROOT=/opt/caffe
WORKDIR $CAFFE_ROOT

# FIXME: use ARG instead of ENV once DockerHub supports this
# https://github.com/docker/hub-feedback/issues/460
ENV CLONE_TAG=1.0

RUN git clone -b ${CLONE_TAG} --depth 1 https://github.com/BVLC/caffe.git . && \
    pip install --upgrade pip

但是，当我运行docker build时。 -t ='docker_t3'，我收到以下错误：

Collecting pip

   ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-YHY519/pip/
You are using pip version 8.1.1, however version 22.0.4 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

由于崩溃的命令为pip install -upgrade pip我不确定当错误时如何避免崩溃消息是您应该考虑通过“ PIP Install -upgrade pip”命令升级。

我该怎么办？
