启动可执行文件时程序因错误而停止

Question

我有一个正在运行的 kivy 应用程序，当我从 vscode 启动它时它运行良好。但是当我尝试用

制作一个exe文件时

pyinstaller --onefile --icon=icons/levermannApp.ico --exclude-module matplotlib LevermannApp.py

然后启动程序我得到这个错误信息

     Window.size = (550, 700)
 AttributeError: 'NoneType' object has no attribute 'size'

我的部分代码如下所示：

class MyLayout(Widget):
    Window.size = (550, 700)

class LevermannScore(App):
    def build(self):
        return MyLayout()

if __name__ == "__main__":
    LevermannScore().run()

我的规范文件如下所示：

# -*- mode: python ; coding: utf-8 -*-


block_cipher = None


a = Analysis(['LevermannApp.py'],
             pathex=['C:\\Users\\Polzi\\Documents\\DEV\\Python-Private'],
             binaries=[],
             datas=[],
             hiddenimports=[],
             hookspath=[],
             runtime_hooks=[],
             excludes=['matplotlib'],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          [],
          name='LevermannApp',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          upx_exclude=[],
          runtime_tmpdir=None,
          console=True , icon='icons\\levermannApp.ico')

任何想法为什么程序在 vscode 上运行良好但不是可执行文件？ （过去我已经能够使用 pyinstaller 为这个程序制作一个 exe 文件 - 但现在我再次尝试并得到上述错误......）

Answer 1

我想我终于能够解决它 py 定义规范文件如下：

# -*- mode: python -*- 
 
import os
from kivy_deps import sdl2, glew
 
spec_root = os.path.abspath(SPECPATH)
block_cipher = None
app_name = 'LevermannApp'
win_icon = 'icons/levermannApp.ico'
 
a = Analysis(['LevermannApp.py'],
             pathex=['C:\\Users\\Polzi\\Documents\\DEV\\Python-Private'],
             binaries=None,
             datas=[('*.kv', '.')],
             hiddenimports=['win32timezone'],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          [],
          exclude_binaries=True,
          name=app_name,
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=False,
          console=False,
          icon=win_icon)
coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               *[Tree(p) for p in (sdl2.dep_bins + glew.dep_bins)],
               strip=False,
               upx=False,
               name=app_name)

然后用命令简单地开始编译

pyinstaller LevermannApp.spec

顺便说一句，它不会被编译成单个 exe 文件（我在使用 pyinstaller 时通常会这样做）——但这对我来说不是什么大问题，而且 exe 文件工作正常。 （我会和 Inno Setup 一起使用，最终编译成 setup.exe）
