我在 python 2.7.12 中安装了 pyjnius 模块。我真的不记得我是如何安装它的。
我有一个简单的脚本：
#!/usr/bin/python
from jnius import autoclass
# do something here
我可以运行它而不会出现任何错误，但是当我尝试在 python shell 中编写代码时，它会出错。

我的pyjnius有什么问题吗？
我尝试使用以下方法卸载我当前的 pyjnius 模块：
sudo apt-get purge pyjnius
但它说：
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package pyjnius
我将不胜感激任何提示我的问题。
