我已经按照DKPro Core的安装文档进行自然语言处理，但是发现无论我在Debian Jessie下安装它的方式如何，我都无法使用它。它适用于Groovy，但不适用于Jython，如下所述：
https://dkpro.github.io/dkpro-core/pages/jython-intro/
我已经安装了Oracle Java，jip和jython，然后将jip jar编译（据说，我不确定）为jython。
我最后得到的错误是：
$ jython pipeline.jy

ImportError: No module named requests
我猜大多数人会给我答案，“使用apt-get或pip安装python-requests”。这不起作用。这不是python问题。它是一个jython问题或某种奇怪的环境问题。我很欣赏如何让它发挥作用。
