问题描述
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

from _dbus_bindings import (

以下是我想问的一些输出:

有人可以帮助我吗?我在这里错过明显地明显的东西吗?
谢谢.
我遇到了类似的问题，在少数情况下dbus和python 开箱即用时效果不佳.共识似乎是您需要系统级安装(即apt-get)才能使dbus正常工作.我相信您看到的/home/e/anaconda3/lib/python3.5/site-packages/_dbus_bindings.so: undefined symbol: _Py_ZeroStruct错误与之直接相关.
conda install dbus不会向~/anaconda3/lib/python3.6/site-packages添加任何内容，而是似乎在~/anaconda3/bin/中安装了某些可执行文件，例如dbus-run-session，dbus-daemon等.这在您分析dbus tarball的内容时有些道理 https://anaconda.org/conda-forge/dbus ，因为它都是C文件，可执行文件.我不确定它应该是dbus python模块，但我可能是错的.
我搜索了conda存储库，发现一些人上载了dbus-python版本，大概是他们编译并安装了.我通过以下方式在py3.6 conda环境中尝试了此
conda install -c scottwales dbus-python
然后，我能够导入dbus.这是一种骇人听闻的方法，不应在生产中使用，我建议您听一下卡洛斯·科尔多瓦(Carlos Cordoba)的下方.但是，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.

DBus is working fine on the system python, however not working on Anaconda Python.

Can anyone help me? Am I missing something blatantly obvious here?
Thanks in advance.
I had similar issues, there are few cases where dbus and python don't work well out-of-the-box. The consensus appears to be that you need a system-level install (i.e. apt-get) to get dbus to work. I believe the /home/e/anaconda3/lib/python3.5/site-packages/_dbus_bindings.so: undefined symbol: _Py_ZeroStruct error you're seeing is directly related to that.
conda install dbus does not add anything to ~/anaconda3/lib/python3.6/site-packages, but instead appears to install some executables in ~/anaconda3/bin/ like dbus-run-session, dbus-daemon, etc. This makes some sense when you analyze the contents of the dbus tarball https://anaconda.org/conda-forge/dbus, as it's all C files and executables. I'm not sure it's supposed to be the dbus python module, but I could be wrong.
EDIT:
I searched the conda repositories and found a few individuals that uploaded a version of dbus-python, presumably that they compiled and installed. I tried this one out in a py3.6 conda environment via:
conda install -c scottwales dbus-python
I was then able to import dbus. This is a hacky approach and should not be used in production, I'd recommend listening toCarlos Cordoba's post below. But if you need a solution now, search through some user conda packages or try to compile the library yourself.
