pip无法安装dbus-python

Question

我计划安装dbus-python。

$ pip --version; python --version
pip 19.0.3 from /home/me/anaconda3/lib/python3.7/site-packages/pip (python 3.7)   
Python 3.7.3

平台

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.10
Release:    18.10
Codename:   cosmic

运行pip install dbus-python时，它会报告错误：

  checking for DBUS... no
  configure: error: in `/tmp/pip-install-hr9djbwg/dbus-python/build/temp.linux-x86_64-3.7':
  configure: error: The pkg-config script could not be found or is too old.  Make sure it
  is in your PATH or set the PKG_CONFIG environment variable to the full
  path to pkg-config.

  Alternatively, you may set the environment variables DBUS_CFLAGS
  and DBUS_LIBS to avoid the need to call pkg-config.
  See the pkg-config man page for more details.

检查

$ echo $PKG_CONFIG
#return nothing 

我刚刚安装了pkg-config

$ pkg-config --version
0.29.1

它仍然会报告错误

  checking for DBUS... no
  configure: error: Package requirements (dbus-1 >= 1.8) were not met:

  No package 'dbus-1' found

  Consider adjusting the PKG_CONFIG_PATH environment variable if you
  installed software in a non-standard prefix.

  Alternatively, you may set the environment variables DBUS_CFLAGS
  and DBUS_LIBS to avoid the need to call pkg-config.
  See the pkg-config man page for more details.

但是，不能安装dbus-1

$ pip install dbus-1
Collecting dbus-1
  Could not find a version that satisfies the requirement dbus-1 (from versions: )
No matching distribution found for dbus-1

Answer 1

我遇到了同样的问题

首先，我查找sudo apt-cache search dbus-1包

然后我使用以下命令安装了所需的软件包：sudo apt install libdbus-1-3 libdbus-1-dev

希望它能为你工作

Answer 2

遇到了同样的问题。dbus-python似乎是一个被弃用的模块。dbus-next似乎是它的替代品。

pip install dbus-next
