python - 在 amazon/aws-cli docker 镜像上安装 python 3.9

Question

如何在 amazon/aws-cli docker 镜像之上安装 Python 3.9，默认情况下 python 2.7 附带？到目前为止，我所尝试的是基于在 Amazon Linux 2 上安装 Python 3 的安装教程的这些系列命令:

FROM amazon/aws-cli:latest

WORKDIR ./

COPY ./.aws ./root/.aws

COPY . .

RUN yum install gcc openssl-devel bzip2-devel libffi-devel -y
RUN yum install wget tar -y
RUN cd /opt
RUN wget https://www.python.org/ftp/python/3.9.6/Python-3.9.6.tgz
RUN tar xzf Python-3.9.6.tgz
RUN cd Python-3.9.6
RUN ./configure --enable-optimizations
RUN make altinstall
RUN rm -f /opt/Python-3.9.6.tgz

RUN ["python3", "-u", "app.py"]

但是我收到这个错误:

您还必须安装 gzip 和 make 并使用 WORKDIR:

FROM amazon/aws-cli:latest

WORKDIR ./

COPY ./.aws ./root/.aws

COPY . .

RUN yum install gcc openssl-devel bzip2-devel libffi-devel gzip make -y
RUN yum install wget tar -y
WORKDIR /opt
RUN wget https://www.python.org/ftp/python/3.9.6/Python-3.9.6.tgz
RUN tar xzf Python-3.9.6.tgz
WORKDIR /opt/Python-3.9.6
RUN ./configure --enable-optimizations
RUN make altinstall
RUN rm -f /opt/Python-3.9.6.tgz

RUN ["python3", "-u", "app.py"]
