长话短说，我已经通过apt-get在pi上安装了PyQt 5。除了QWebEngineView之外，一切似乎都很好。出于某种原因，我收到了这样的信息：
ImportError：没有名为'PyQt 5的模块。QtWebEngineWidgets'时，我试图导入它。
PyQt 5版本：5.8.2
有人知道吗？
提前感谢您的时间。apt-cache search pyqt5返回

**注意：**QtWebEngineWidgets通常无法在Windows下使用v3之前的Python版本。5、编译器不兼容。

问题是他们忘了编译qtwebkit和-engine。或者你自己下载并编译，或者你降级到更低的版本。对于Mac：pip 3 install PyQt 5 ==5。10（这是一个稳定的版本）。

QtWebEngine需要单独安装。
您可以在安装时将这一行更改为使用apt-get。
您可能需要根据代码导入模块和子模块。
您是否从第三方服务器安装自定义PyQt 5构建以使用优先级编解码器？

QtWebEngine基于Chromium，这是一个很大的工具包。
因此不适用于所有平台/不兼容。
也许降级到基于QtWebKit的是一个更可能的解决方案。
