我正在处理一些代码，这些代码需要python qt 5中的一些软件包。导入QWebPage模块时，我得到了一个丢失的软件包错误：
from PyQt5.Qt import QWebPage, QWebSettings
ImportError: cannot import name 'QWebPage'
我正在使用debian并已经安装了软件包：libqtwebkit-devfrom，libqtwebkit-dev和libqt5webkit5-dev。我目前的套餐是：

我错过了什么？
修改
安装python3-pyqt5.qtwebkit后，我收到以下缺少的模块错误：
from Cython.Compiler.Options import normalise_encoding_name
ImportError: No module named 'Cython'
我使用pip安装了cython：
# pip install cython
并且python3.4需要cython：
# apt-get install python3-pip
pip3 install cython
编辑＃2：
接下来，python3.4需要pymongo：
from pymongo.connection import Connection
ImportError: No module named 'pymongo.connection'
我使用pip3安装了软件包：
pip3 install pymongo
但是python还是找不到它，为什么？
编辑＃3：
阅读this问题似乎pymongo 3.x.x不再有连接类。
$ pip freeze | grep pymongo
pymongo==3.2
编辑＃4：
我尝试降级pymongo，但错误仍然存在：
pip install pymongo==2.7.2
编辑＃5：
要将pymongo与python3.4一起使用，应与pip3一起安装：
pip3 install pymongo==2.7.2
