在 dockerfile 中安装 jython 时出现 NotImplementedError

Question

我有一个基于1.7.0_45 JAVA 的Dockerfile，我想在其中安装jython。这就是我根据this 实现的方式：

FROM java:7.0_45
MAINTAINER Zeinab Abbasimazar (zeinab.abbasi@peykasa.ir)
ENV JYTHON_VERSION=2.7.0
RUN apt-get update; \
    apt-get install -y --no-install-recommends apt-utils; \
    apt-get install -y curl; \
    curl -Lo jython-installer-$JYTHON_VERSION.jar \
    "http://search.maven.org/remotecontent?filepath=org/python/jython-installer/$JYTHON_VERSION/jython-installer-$JYTHON_VERSION.jar"; \
    java -jar jython-installer-$JYTHON_VERSION.jar -s -t minimum -i mod -i ensurepip -d /usr/local/jython-$JYTHON_VERSION; \
    rm -f jython-installer-$JYTHON_VERSION.jar; \
    ln -s /usr/local/jython-$JYTHON_VERSION/bin/* /usr/local/bin/
RUN java -version
ENTRYPOINT ["bash"]

java:7.0_45 是从内部存储库下载的。

java -version 的输出为：

java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

在构建阶段，我得到了这个：

Congratulations! You successfully installed Jython 2.7.0 to directory /usr/local/jython-2.7.0.

jython 在运行阶段工作正常，但我很好奇导致此错误的原因。有什么有用的信息吗？

编辑 1：

我应该提到我在ubuntu 16.04 系统上安装它没有问题。

我已经通过在 apt-get 下载列表中添加 python 解决了这个问题：

apt-get install -y curl python2.7 python-dev

现在，这是输出：
