靠运气解决kali_linux上pyzo的问题

本来使用sublime text3也可以做python的IDE，但是我也想试试pyzo。
安装的过程很和平。没有任何报错

apt-get install pyzo

但是一启动就报错.

pyzo
Started our command server
Segmentation fault

查看/var/log/messages就看到这么一行

Aug 13 17:48:18 kali kernel: [14934.509890] pyzo[4410]: segfault at 0 ip 00007f8688607561 sp 00007fff914d47b0 error 6 in QtCore.cpython-36m-x86_64-linux-gnu.so[7f86884aa000+161000]

思考了下，决定从这个.so(Shared Object)入手。
先找找这个文件在哪里。

locate QtCore.cpython-36m-x86_64-linux-gnu.so
/usr/lib/python3/dist-packages/PyQt4/QtCore.cpython-36m-x86_64-linux-gnu.so
/usr/lib/python3/dist-packages/PyQt5/QtCore.cpython-36m-x86_64-linux-gnu.so

有点意思，应该是pyqt5和pyqt4都提供了这个文件。确认下提供这个文件的包名。

dpkg -S /usr/lib/python3/dist-packages/PyQt4/QtCore.cpython-36m-x86_64-linux-gnu.so
python3-pyqt4: /usr/lib/python3/dist-packages/PyQt4/QtCore.cpython-36m-x86_64-linux-gnu.so
dpkg -l |grep pyqt

我决定把python3-pyqt4给卸掉试试运气。

apt-get remove python3-pyqt4
#call pyzo again
pyzo

    from PySide import __version__ as PYSIDE_VERSION  # analysis:ignore

During handling of the above exception, another exception occurred:

    raise PythonQtError('No Qt bindings could be found')
qtpy.PythonQtError: No Qt bindings could be found

我的运气就这么来了， No module named 'PySide'. 装上Pyside

root@kali:/usr/local/src/py# apt-cache search pyside

#此处删掉了50行 -for brevity

root@kali:/usr/local/src/py# apt-get install python3-pyside

然后再运行pyzo.
