web_browser_main.py

from PyQt5 import QtCore,QtWidgets

class TestbrowserCode:
    def __init__(self):

        self.main_ui.chat_browser.show()

program = TestbrowserCode()
  1. 从源代码运行代码：
Χρήστος@Chris-pc MINGW64 /c/python/scripts/Papinhio player/notes
$ python web_browser_main.py

（网站显示正确）

  1. 制作 .exe 文件 (full result here)
Traceback (most recent call last):
  File "C:/Python/Scripts/Papinhio player/notes/web_browser_main.py",line 4,in
 
    from PyQt5.QtWebKitWidgets import QWebView,QWebPage
  File "",line 991,in _find_and_load
  File "",line 975,in _find_and_load_unlocked
  File "",line 657,in _load_unlocked
  File "",line 556,in module_from_spec
  File "",line 1101,in create_module

  File "",line 973,in _find_and_load_unlocked
ModuleNotFoundError: No module named 'PyQt5.QtWebKit'
[17208] Failed to execute script web_browser_main

结果错误导入PyQt5.QtWebKitWidgets

msys2 mingw64 控制台中的所有内容。 如何编译上述文件？

解决方法

pyinstaller --onefile --hidden-import PyQt5.QtWebKit web_browser_main.py

上层代码包括缺少的模块QtWebKit。 我建议使用 --onedir 而不是 --OneFile 因为我认为输出 exe 更稳定。 （在像 web_browser_main 应用程序这样的应用程序中几秒钟后，我遇到了 Segmentfault 运行时错误）

现在工作！！！
