长话短说我已经通过apt-get在我的pi上安装了PyQt5。除了QWebEngineView之外，一切似乎都能正常工作。出于某种原因，我收到了这条消息：
ImportError：我尝试导入时没有名为'PyQt5.QtWebEngineWidgets'的模块。
PyQt5版本：5.8.2
任何人都有任何想法？
提前感谢您的时间。

pyqt5 - Build of PyQt5 compiled for eglfs Qt5 and Python3 on Raspbian
答案 0 :(得分：0)
注意：由于编译器不兼容，使用早于v3.5的Python版本的Windows通常不提供QtWebEngineWidgets。

答案 1 :(得分：0)
问题是他们忘了编译qtwebkit和-engine。 或者，您可以下载并自己编译，或者降级到较低版本。 对于Mac：pip3 install PyQt5 == 5.10（这是一个稳定的版本）。
答案 2 :(得分：-1)
QtWebEngine基于铬，这是一个很大的工具包。
，因此不适用于所有平台。
也许降级到基于QtWebKit的解决方案对您来说更可能。
