Docker问题:/bin/sh:pip:找不到 [英] Docker issue: /bin/sh: pip: not found

问题描述

所以我的dockerfile是:

So my dockerfile is :

FROM iron/python:2.7

WORKDIR /app
ADD . /app

RUN pip install --upgrade pip
RUN pip install -r ./requirements.txt

最近，当我使用以下命令构建图像时: docker build --no-cache -t <image name>:<tag>

Recently though when I build my image with: docker build --no-cache -t <image name>:<tag>

我遇到了以下问题:

Step 4/6 : RUN pip install --upgrade pip
---> Running in 00c781a53487
/bin/sh: pip: not found
The command '/bin/sh -c pip install --upgrade pip' returned a non-zero code: 127

是否对docker进行了任何更改，可能会导致这种情况?因为上周一切都很好，并且使用相同的精确代码构建映像没有问题.

was there any changes to docker that might have caused this? Because last week this was all fine and there were no issues building the image with the same exact code.

推荐答案

您必须先安装pip.

FROM iron/python:2.7
WORKDIR /app
ADD . /app
RUN set -xe \
    && apt-get update \
    && apt-get install python-pip
RUN pip install --upgrade pip
RUN pip install -r ./requirements.txt
