Cannot import QtWebKitWidgets in PyQt5
提问by Peter Bingham
I've recently upgraded PyQt5 from 5.5.1 to 5.6.0 using the Windows 32-bit installer here: https://www.riverbankcomputing.com/software/pyqt/download5. I've also upgraded my python from 3.4 to 3.5.
我最近使用 Windows 32 位安装程序将 PyQt5 从 5.5.1 升级到 5.6.0：https://www.riverbankcomputing.com/software/pyqt/download5 。我还将我的 python 从 3.4 升级到 3.5。
When I run my old code (which used to work) with the latest version I get an exception:
当我使用最新版本运行旧代码（曾经可以工作）时，出现异常：
from PyQt5.QtWebKitWidgets import *
ImportError: No module named 'PyQt5.QtWebKitWidgets'
All of my QT calls in my python occur consecutively and are (and I know I shouldn't be importing * but that's beside the issue here I think):
我在 python 中的所有 QT 调用都是连续发生的（我知道我不应该导入 * 但我认为这是这里的问题之外）：
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyQt5.QtWebKitWidgets import *
So the QtCore, QtGui and QtWidgets imports are all OK.
所以 QtCore、QtGui 和 QtWidgets 导入都没有问题。
Also, when I search the source for QtWebKitWidgets there appears several references to this module.
此外，当我搜索 QtWebKitWidgets 的源时，会出现对该模块的多个引用。
Finally my python path looks like:
最后我的python路径看起来像：
C:\PYTHON35;C:\PYTHON35\DLLs;C:\PYTHON35\LIB;C:\PYTHON35\LIB\LIB-TK;
and environment path:
和环境路径：
C:\Python35\Lib\site-packages\PyQt5;C:\Python35;C:\Python35\Lib;C:\Python35\Lib\site-packages;C:\Python35\Scripts ....

QtWebKitgot deprecated upstream in Qt 5.5 and removed in 5.6.
QtWebKit在 Qt 5.5 上游弃用并在 5.6 中删除。
You may want to switch to PyQt5.QtWebEngineWidgets:
你可能想切换到PyQt5.QtWebEngineWidgets：
This supercedes the QtWebKit module and provides better and up-to-date support for HTML, CSS and JavaScript features
这取代了 QtWebKit 模块，并为 HTML、CSS 和 JavaScript 功能提供了更好和最新的支持

In PyQt5 "QtWebKitWidgets"is Deprecated. I just replace this line
在 PyQt5 中，“QtWebKitWidgets”已弃用。我只是替换这一行
from PyQt5.QtWebKitWidgets import QWebView, QWebPage
from PyQt5.QtWebKit import QWebSettings
With this code:
使用此代码：
from PyQt5.QtWebEngineWidgets import QWebEngineView as QWebView,QWebEnginePage as QWebPage
from PyQt5.QtWebEngineWidgets import QWebEngineSettings as QWebSettings

In PyQt5 "QtWebKitWidgets"is no longer available. Instead it is replaced with "QtWebEngineWidgets".So you have to make this change in your code.
在 PyQt5 中，“QtWebKitWidgets”不再可用。相反，它被替换为“QtWebEngineWidgets”。因此，您必须在代码中进行此更改。

If you reallywant to use PyQt5.QtWebKitWidgets, you could run this from the command line:
如果你真的想使用PyQt5.QtWebKitWidgets，你可以从命令行运行它：
pip install PyQtWebKit
and let it do what it does.
让它做它该做的。
