How to install pyyaml 3.12? with python 3.6 or python 3.7 base image

推荐答案

您需要安装 PyYAML == 3.12 为您的aws-sam-cli
，因为Docker映像默认带有 pyyaml 5.1 ，它与 aws兼容-sam-cli 。在安装 aws-sam-cli

You need to install PyYAML==3.12 for your aws-sam-clias you Docker image come with pyyaml 5.1 by default which have compatibility issue with aws-sam-cli. All you need to install pyyaml 3.12 before installation of aws-sam-cli

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