在Dockerfile中安装jython时出现NotImplementedError

我有一个基于1.7.0_45 JAVA的1.7.0_45 ，我想在其中安装jython 。 这是我如何根据这个实现的 ：

 FROM java:7.0_45 MAINTAINER Zeinab Abbasimazar ([e-mail]) 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的输出是：

 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build阶段，我得到了这个：

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

虽然jython在运行阶段工作正常，但我很好奇是什么原因导致这个错误。 任何可以帮助的信息？

编辑1：

我应该提到，我没有问题在ubuntu 16.04系统上安装它。

我已经通过在apt-get下载列表中添加python来解决该问题：

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

现在，这是输出：
