当我的应用程序由 pyinstaller 创建的 exe 文件时，它不断显示错误，现在这是我发现的最后一个错误
Traceback (most recent call last):

我想在exe文件中添加所有图像和kivy文件，它应该独立于任何依赖项，以便我可以分发

不确定这是否是问题所在，但查看我的一个项目中的工作规范文件，我发现我必须在规范文件的顶部包含
from kivy_deps import sdl2, glew exeexe = EXE(pyz,
a.scripts,
a.binaries,
a.zipfiles,
a.datas,
*[Tree(p) for p in (sdl2.dep_bins + glew.dep_bins)],
.
.
.
我也需要：
hiddenimports=['win32timezone'],
在
Analysis另请注意，一旦有了
specpyinstaller <name of spec file>add-datahidden-importspec刚刚添加了这段代码 '如果name==“main”： #从这一行开始 如果 hasattr(sys, '_MEIPASS'): resource_add_path(os.path.join(sys._MEIPASS)) #对此 测试分析().run()`
并修改了pyinstaller代码（只是删除了所有kivy相关代码）
pyinstaller --onefile -w --add-data="thelab.kv:." --add-data="图像 (1).jpg:." --add-data="屏幕截图 (23).png:." --add-data="屏幕截图 (24).png:." --add-data="屏幕截图 (25).png:." --add-data="KivyAppData.db:." --add-data="AppIcon.ico:" --icon=AppIcon.ico --hidden-import plyer.platforms.win.filechooser TestAnalysis.py
然后我就能够成功地将文件转换为一个 exe 文件，我没有修改规范文件中的任何内容
