qpaeq 没有​​名为 dbus 的模块

qpaeq 没有​​名为 dbus 的模块

笔记：这个问题dbus与我遇到的下述问题无关。

我尝试qpaeq在安装后运行。它要求dbus。其他帖子说要安装python-dbus。这没用。也没有dbus-python，这就是qpaeq要求的。该怎么办？抄录如下：

答案1

如果出现此错误，则可能需要几个模块，如上面的注释中所述。如果希望更改永久生效，则需要从 加载模块/etc/pulse/default.pa。将以下几行添加到文件底部：

load-module module-equalizer-sink
load-module module-dbus-protocol

您可以使用 触发更改立即生效pulseaudio -k。

答案2

我遇到了同样的问题。

对我来说，这是由于本地安装的版本pyqt5可能不是最新的（或者缺少系统打包程序提供的某些内容）造成的。

您可以通过以下方式检查：

$ python
Python 3.9.2 (default, Feb 20 2021, 18:40:11)
[GCC 10.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import dbus.mainloop; print(dbus.mainloop)
<module 'dbus.mainloop' from '[PATH]'>

如果 的值[PATH]指向你的主目录的某个地方（例如从 开始/home/...），那么你已经在本地安装了 pyqt5，并且它可能删除它是个好主意，离开那里只有包管理器安装了一个。

使用 ( 删除它无需使用 sudo）通过发出pip uninstall pyqt5（它会询问并显示您从哪里删除包，应该[PATH]与之匹配）。
