错误: serverlessrepo 0.1.8需要pyyaml~=3.12

Question

下面是带有基本图像python 3.7的docker文件：

FROM python:3.7-alpine3.9


ENV HOME /home/someteam
ENV PATH $HOME/.local/bin:$PATH
RUN ln -fs /usr/share/zoneinfo/Etc/UTC /etc/localtime
RUN apk add --no-cache --virtual .build-deps python2-dev  python3-dev gcc linux-headers musl-dev && \
    addgroup someteam --gid=5566; \
    adduser -G someteam -Du 5566 -h /home/someteam -s /bin/bash someteam; \
    chown -R someteam $HOME;
RUN apk add --no-cache groff less bash jq curl py-pip tzdata
USER someteam

WORKDIR $HOME

RUN pip install --user --upgrade awscli aws-sam-cli;
USER root

RUN apk del .build-deps; \
    rm -rf /var/cache/apk/*

USER someteam
WORKDIR $HOME

ADD somescript.sh $HOME/somescript.sh

给出错误：

ERROR: serverlessrepo 0.1.8 has requirement pyyaml~=3.12, but you'll have pyyaml 5.1 which is incompatible.
ERROR: aws-sam-cli 0.18.0 has requirement PyYAML~=3.12, but you'll have pyyaml 5.1 which is incompatible.

如何安装pyyaml 3.12？带有python 3.6或python 3.7基映像

Answer 1

您需要为您的aws安装PyYAML==3.12，因为您的Docker映像默认带有pyyaml 5.1，这与aws-sam-cli有兼容性问题。在安装pyyaml 3.12之前，只需安装aws-sam-cli

RUN pip install PyYAML==3.12
USER someteam
WORKDIR $HOME
RUN pip install --user --upgrade awscli aws-sam-cli;
USER root

Answer 2

在此拉请求释放后，无服务器回购应该在5.1上。根据公共关系，SAM将很快升级到5.1。
