使用 pyinstaller 时没有名为 kivymd.effects 的模块

Question

嗨，任何人都可以帮忙解决这个问题，当我尝试运行它时，我的 exe 文件抛出了这个错误，并且我在 main.spec 文件中将 kivymd 添加到了我的 hiddenimports=["kivymd"] 中，我也尝试安装kivymd 使用 pip 但仍然抛出错误。

    Traceback (most recent call last):
  File "kivy\lang\parser.py", line 472, in execute_directives
ModuleNotFoundError: No module named 'kivymd.effects'

During handling of the above exception, another exception occurred:

我为同样的问题苦苦挣扎了几天，所以这里是解决方法。

pyinstaller 没有导入效果模块，因为它不包含在 kivymd 钩子列表（kivymd_hooks_path）中，所以您需要手动添加它：

首先转到 ...\AppData\Local\Programs\Python\Python38\Lib\site-packages\kivymd （或任何您的 kivymd 路径并修改 __init__.py 以添加效果路径：

原文：

....

path = os.path.dirname(__file__)
"""Path to KivyMD package directory."""

fonts_path = os.path.join(path, f"fonts{os.sep}")
"""Path to fonts directory."""

images_path = os.path.join(path, f"images{os.sep}")
"""Path to images directory."""

...

修改：

....

    path = os.path.dirname(__file__)
    """Path to KivyMD package directory."""
    
    fonts_path = os.path.join(path, f"fonts{os.sep}")
    """Path to fonts directory."""
    
    images_path = os.path.join(path, f"images{os.sep}")
    """Path to images directory."""
    
    effects_path = os.path.join(path, f"effects{os.sep}")
    """Path to effects directory."""

...

第二次转到 ...\kivymd\tools\packaging\pyinstaller 并修改 hook-kivymd.py 并添加效果路径：

datas = [
    (
        kivymd.fonts_path,
        str(Path("kivymd").joinpath(Path(kivymd.fonts_path).name)),
    ),
    (
        kivymd.images_path,
        str(Path("kivymd").joinpath(Path(kivymd.images_path).name)),
    ),
    (
        kivymd.effects_path,
        str(Path("kivymd").joinpath(Path(kivymd.effects_path).name)),
    ),
]

一旦完成，创建一个新的可分发，就是这样：D
