ModuleNotFoundError: No module named 'PyQt5.QtWebEngineWidgets'

[MatthewZMD]

I already pip installed pyqt5 according to README sudo pip install dbus-python PyMuPDF grip qrcode pyqt5 python-xlib

When I try to open a pdf file, minibuffer gives this error:*eaf* exited abnormally with code 1

This is what I am seeing in *eaf* buffer:

Traceback (most recent call last):
  File "/home/matthewzmd/.emacs.d/site-elisp/emacs-application-framework/eaf.py", line 25, in <module>
    from app.browser.buffer import AppBuffer as NeverUsed # noqa

    from core.browser_buffer import BrowserBuffer

    from PyQt5.QtWebEngineWidgets import QWebEngineView, QWebEnginePage, QWebEngineContextMenuData
ModuleNotFoundError: No module named 'PyQt5.QtWebEngineWidgets'

this and that didn't solve the problem.

Another error seems to occur:

File "/home/matthewzmd/.emacs.d/site-elisp/emacs-application-framework/core/browser.py", line 25, in <module>
    from PyQt5.QtWebEngineWidgets import QWebEngineView, QWebEnginePage, QWebEngineContextMenuData

操作系统提供的 PyQt5 有问题，不是EAF本身的问题。

[MatthewZMD]

Manjaro系统, 该怎么修复呢...

我也碰到同样的问题，试试: pip install PyQtWebEngine

今天用回了Manjaro KDE，又遇到了这个问题:

ImportError: /usr/lib/python3.7/site-packages/PyQt5/Qt/lib/libQt5WebEngineCore.so.5: symbol _ZSt24__throw_out_of_range_fmtPKcz version Qt_5 not defined in file libQt5Qml.so.5 with link time reference

一狠心直接删掉整个PyQt5文件夹，全部重装

sudo rm -rf /usr/lib/python3.7/site-packages/PyQt5/
sudo pip uninstall PyQt5
sudo pip uninstall PyQt5-sip
sudo pip uninstall PyQt5WebEngine
sudo pip install PyQt5
sudo pip install PyQt5-sip
sudo pip install PyQt5WebEngine

Problem fixed haha

这是 Arch 的锅，系统升级后要重新跑一遍 pip

哎 这问题真麻烦
