python 的一个非常奇怪的问题

首先，我对咖啡因有问题： 咖啡因在 Ubuntu 17.10 上不起作用

我没有用python绑定它。顺便说一句，在Xorg下运行ubuntu没有帮助。

其次，当我尝试测试 Python 程序时，我收到了奇怪的错误。我运行了

 python3 programname.py test

并收到

File "sampletest.py", line 1, in <module>
    import unittest
  File "/usr/lib/python3.6/unittest/__init__.py", line 59, in <module>
    from .case import (TestCase, FunctionTestCase, SkipTest, skip, skipIf,

    import logging

    from string import Template

Error in sys.excepthook:

  File "/usr/lib/python3.6/email/quoprimime.py", line 44, in <module>
    from string import ascii_letters, digits, hexdigits
ImportError: cannot import name 'ascii_letters'

然后我运行alacarte后收到错误：我如何按字母顺序对 Xfce 的 whisker 菜单列表进行排序？

顺便说一句，运行 menulibre 时我收到了类似的错误：

/usr/lib/python3/dist-packages/menulibre/MenuEditor.py:28: PyGIWarning: GMenu was imported without specifying a version first. Use gi.require_version('GMenu', '3.0') before import to ensure that the right version gets loaded.

    menu = MenuEditor()

    self.load()

    if not self.tree.load_sync():
GLib.Error: g-markup-error-quark: Error on line 1 char 1: Document was empty or contained only whitespace (1)

我确定我的 Python 解释器有问题，但我不知道是什么问题。请帮忙

PS 我是 Linux 新手。所以，请尽可能简单地解释一下

PPS 我有 Ubuntu 17.10

对于menulibre部分，您应该重新安装它及其依赖项：

sudo apt-get update
sudo apt-get install --reinstall gir1.2-gmenu-3.0 gnome-menus libgnome-menu-3-0 menulibre

menulibre然后使用命令或菜单启动它。
