我正在编写一些需要 python qt 5 中的多个包的代码。在导入 QWebPage 模块时出现丢失包错误:
from PyQt5.Qt import QWebPage, QWebSettings
ImportError: cannot import name 'QWebPage'
我正在处理 debian 和已安装的软件包:libqtwebkit-devfrom、libqtwebkit-dev 和 libqt5webkit5-dev。我当前的包是:

我错过了什么？
编辑:
安装python3-pyqt5.qtwebkit后，我收到以下丢失模块错误:
from Cython.Compiler.Options import normalise_encoding_name
ImportError: No module named 'Cython'
我已经使用 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'
我已经使用 pip3 安装了软件包:
pip3 install pymongo
但是python还是找不到，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:
为了将pymongo与python3.4一起使用，它应该与pip3一起安装:
pip3 install pymongo==2.7.2
最佳答案
关于python - python3.4中的QWebPage和pymongo在哪里可以找到？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35095894/
