Question

我用virtualwrapper，virtualen和pthon3设置了一个名为“ ComputerVision”的虚拟环境。

一切正常，除了在我的python脚本中导入dbus之外。我想使用python3，但是如您所见： -dbus可以使用python2而不是python3导入 -cv2可以与python3而不是python 2一起导入

(ComputerVision) pi@raspberrypi:/ $ python3

>>> import dbus
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named 'dbus'
>>> import cv2
>>> exit()
(ComputerVision) pi@raspberrypi:/ $ python2

如何解决它，以便将dbus导入到我的python3脚本中？

谢谢。

您需要为Python3安装dbus-python库：

pip3 install dbus-python

dbus无法在虚拟环境中使用python3？
