导入错误：没有名为 dbus 的模块

导入错误：没有名为 dbus 的模块

我试图更新我的 Python 但结果却搞乱了整个系统。

我现在可以启动我的软件中心了。我尝试在 Google 上搜索多种修复方法，但都无济于事。我的软件中心无法启动。

当我尝试启动它时，显示以下错误：

astephen@localhost:/usr/bin$ ./software-centerGtk-Message: Failed to load module "gtk-vector-screenshot"
Traceback (most recent call last):
File "./software-center", line 36, in <module>
from softwarecenter.utils import (
File "/usr/share/software-center/softwarecenter/utils.py", line 19, in <module>
import dbus
ImportError: No module named dbus

我尝试dbus使用以下方法重新安装：

apt-get install --reinstall dbus

但这并没有什么帮助。

答案1

快速搜索后发现，Python DBUS 模块的 Debian 软件包名称为python-dbus（或python3-dbus）。为什么它尽管是该软件包的显式依赖项却不可用，software-center我不明白。您应该重新安装这两个软件包，以防它们损坏：

sudo apt-get install --reinstall software-center python-dbus

答案2

好吧，这个问题已经问了两年了，但这并没有阻止我在同一个问题上浪费时间。

pip3 install dbus-python

让我遇到了一些问题，例如：

...

安装或重新安装我当前的任何软件都无济于事。但我意识到这是一个 python3.7 问题：

与在 python2.7 中一样，可以添加 import dbus，但在 pyhon3.7 中它失败并出现相同的错误：

Traceback (most recent call last):
    import dbus
  File "/usr/lib/python3/dist-packages/dbus/__init__.py", line 77, in <module>
    import dbus.types as types
  File "/usr/lib/python3/dist-packages/dbus/types.py", line 6, in <module>
    from _dbus_bindings import (
ModuleNotFoundError: No module named '_dbus_bindings'

解决方案相当简单：

sudo apt-get install python3.7-dev
pip3 install dbus-python

答案3

您必须使用或安装dbus-python包：pippip3

pip3 install dbus-python

或者

pip install dbus-python

您可能需要sudo在上述命令之前。

答案4

如果您的 python3 模块找不到正确版本的软件包，则可能的一种方法是创建指向旧版本的符号链接。 如果是 dbus，您可以执行以下操作。 （假设您刚刚将 python3.5 升级到 python3.6） $ cd /usr/lib/python3/dist-packages/ $ ln -s _dbus_glib_bindings.cpython-{35m,36m}-x86_64-linux-gnu.so

如果遇到更多错误，请尝试链接所有包。

a=$(find /usr/lib/python3/dist-packages -name '*35m*so')
b=$(echo $a | tr 35m 36m)
IFS=' ' read -r -a a <<< $a
IFS=' ' read -r -a b <<< $b

for ((i=0;i<${#a[@]};++i)); do
    ln -s "${a[i]}" "${b[i]}"
done
