Python3 dbus 导入错误：未定义符号：_Py_ZeroStruct

Question

我正在尝试将 python-mbus 用于 python 3，我已经安装了它

sudo apt-get install python3-dbus

但是导入失败：

asdf@asdf:~$ python3
Python 3.6.3 (default, Oct  3 2017, 21:16:13) 
[GCC 7.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import dbus
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.6/dist-packages/dbus/__init__.py", line 77, in <module>
    import dbus.types as types
  File "/usr/local/lib/python3.6/dist-packages/dbus/types.py", line 6, in <module>
    from _dbus_bindings import (
ImportError: /usr/local/lib/python3.6/dist-packages/_dbus_bindings.so: undefined symbol: _Py_ZeroStruct

我也安装了它：

pip3 uninstall dbus-python

但我仍然遇到同样的错误：

asdf@asdf:~$ python3
Python 3.6.3 (default, Oct  3 2017, 21:16:13) 
[GCC 7.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

  File "/home/asdf/.local/lib/python3.6/site-packages/dbus/types.py", line 6, in <module>
    from _dbus_bindings import (
ImportError: /home/asdf/.local/lib/python3.6/site-packages/_dbus_bindings.so: undefined symbol: _Py_ZeroStruct

这是在 sys.path:

>>> print (sys.path)
['', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', '/home/asdf/.local/lib/python3.6/site-packages', '/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages', '/usr/lib/python3.6/dist-packages']

我在 Debian GNU/Linux buster/sid 上运行

知道我做错了什么吗？

我不确定我是如何解决这个问题的（无法发表评论），但我遇到了完全相同的问题，我做到了：

sudo pip3 uninstall dbus-python
sudo aptitude update && sudo aptitude upgrade
sudo aptitude -f

之后 aptitude 提醒我 Python 存在一些依赖性问题，我将安装在 Ubuntu Xenial 上的 Python 版本“降级”为 Artful 提供的默认包。现在，Python 3.6.3 上的 import dbus 没有传递任何错误。不过，不知道它是否真的好用。

也许您可以以类似的方式修复它，因为 Debian 和 Ubuntu 软件包通常是相同的。
