更新最新的 PySide 后 Pyinstaller 错误

Question

我有一个可以运行的 python(3.6.8) 和 Pyside(5.12.0) 应用程序。

以前我能够创建一个文件 exe 并且运行良好。

但将 Pyside 更新到 5.12.2 后，我无法运行 app。 有 ModuleNotFoundError: No module named 'typing'

我已经安装了打字模块（pip install typing）。 我尝试卸载 pyside(5.12.2) 并重新安装 pyside(5.12.0)

但我仍然遇到同样的错误。 这是错误。

我在使用 cx_freeze 时遇到了完全相同的问题。在构建 cx_freeze 应用程序并运行后，我得到了错误：

Problem importing shibokensupport:
No module named 'typing'
Traceback (most recent call last):
  File "(builtin)", line 93, in ensure_shibokensupport
  File "(builtin)", line 133, in bootstrap
  File "/tmp/embedded.mp0z2vy0.zip/shibokensupport/signature/loader.py", line 156, in <module>
    import typing

我将typing手动添加到需要包含在cx_freeze setup.py中的包中：

# -*- coding: utf-8 -*-

import sys
from cx_Freeze import setup, Executable

options = {
    'build_exe': {
        'packages': [
            'os',
            'typing'
        ],
        'excludes': [
            'tkinter'
        ]
    }
}

base = None

if sys.platform == 'win32':
    base = 'Win32GUI'

executables = [
    Executable('qt_test1.py', base=base)
]

setup(
    name='qt_test1',
    version='0.1',
    description='My GUI application!',
    options=options,
    executables=executables
)

这样做。它现在运行。

这意味着对于 PyInstaller 你必须这样调用它：

$ pyinstaller your_app.py --hidden-import="typing"

实际上，我不知道 PyInstaller 是否有更好的方法可以将模块显式添加到构建过程中。
