如何在 Anaconda 中使用 Python Dbus 绑定

我正在尝试在 Anaconda python 环境上安装 dbus，但我很挣扎。

这是我收到的错误消息：

e@gateway:~$ python

>>> import dbus

    import dbus.types as types

    from _dbus_bindings import (
ImportError: /home/e/anaconda3/lib/python3.5/site-packages/_dbus_bindings.so: undefined symbol: _Py_ZeroStruct
>>> 

以下是我认为可能会被问到的一些输出：

DBus 在 python 系统上工作正常，但在 Anaconda Python 上无法工作。

Python 2.7：

e@gateway:~$ which python
/usr/bin/python
e@gateway:~$ python

Python 3.5：

e@gateway:~$ python3

谁能帮我？我在这里遗漏了一些明显的东西吗？

提前致谢。

我遇到了类似的问题，很少有 dbus 和 python 的情况开箱即用效果不佳 https://pypi.python.org/pypi/keyring#linux。共识似乎是您需要系统级安装（即apt-get）让 dbus 工作。我相信/home/e/anaconda3/lib/python3.5/site-packages/_dbus_bindings.so: undefined symbol: _Py_ZeroStruct您看到的错误与此直接相关。

conda install dbus没有添加任何东西~/anaconda3/lib/python3.6/site-packages，但似乎安装了一些可执行文件~/anaconda3/bin/ like dbus-run-session, dbus-daemon等等。当您分析 dbus tarball 的内容时，这很有意义https://anaconda.org/conda-forge/dbus https://anaconda.org/conda-forge/dbus，因为它都是 C 文件和可执行文件。我不确定它应该是dbuspython 模块，但我可能是错的。

EDIT:

我搜索了 conda 存储库，发现有几个人上传了 dbus-python 的版本，大概是他们编译并安装的。我试过this one https://anaconda.org/scottwales/dbus-python通过以下方式在 py3.6 conda 环境中输出：

conda install -c scottwales dbus-python

然后我就可以导入 dbus。这是一种 hacky 方法，不应该在生产中使用，我建议听听 卡洛斯·科尔多瓦 (Carlos Cordoba) 的帖子如下。但如果您现在需要解决方案，请搜索一些用户 conda 软件包或尝试自己编译该库。
