PyQt4.QtGui Python错误：非法指令

Question

我试图在Raspbian操作系统上运行pythonpyqt4程序，但它无法执行。在窗户上可以正常工作。我发现导入QtGui时出错。在

令我感到奇怪的是，有些模块正常加载（PyQt4.QtCore），但其他模块会引发错误并重新启动shell（PyQt4.QtGui、PyQt4.QtTest、PyQt4.QtHelp）。在

以下是来自Python shell的错误：

>>> import PyQt4
>>> from PyQt4 import QtCore
>>> from PyQt4 import QtGui
Backend terminated (returncode: -4)
Fatal Python error: Illegal instruction

首先我试着更新设备。。。在

^{pr2}$

。。。但这并没有解决问题。在

所以我试着重新安装python3和pyqt4，但也没用。在

sudo apt-get install --reinstall python3
sudo apt-get install --reinstall python3-pyqt4

如果我检查pyqt4模块，那么应该安装所有的包。在

sudo apt-cache show python3-pyqt4
