【问题描述】：

所以基本上我一直在使用 Kivy 制作应用程序，现在我想使用 pyinstaller 将其编译为单个可执行文件。我按照official kivy guide 和 pyinstaller 规范文件文档中的步骤进行操作（虽然没有那么多），当我尝试运行我的规范文件时，终端打印的内容如下：

我完全不知道为什么会这样，所以我在这里。任何人都知道这个错误和解决方案背后的原因是什么？任何帮助将不胜感激！

这也是我的规范文件：

TPManager.spec

from kivy_deps import sdl2, glew

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


block_cipher = None


a = Analysis(['main.py'],
             pathex=['C:\\Users\\HP\\Desktop\\TPM-Kivy'],
             binaries=[],
             datas=[],
             hiddenimports=[],
             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)

a.datas += [('./main.kv', '.')]
a.datas += [('./Resources', 'Resources')]

exe = EXE(pyz, Tree('C:\\Users\\HP\\Desktop\\TPM-Kivy'),
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          *[Tree(p) for p in (sdl2.dep_bins + glew.dep_bins)],
          name='TPManager',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          upx_exclude=[],
          runtime_tmpdir=None,
          console=True , icon='GUIIcon.ico')

【问题讨论】：

我怀疑错误来自Tree('C:\\Users\\HP\\Desktop\\TPM-Kivy')。如果删除那段代码会发生什么？
我尝试删除那个位，不，仍然是同样的错误。无论哪种方式，它仍然是强制性的，以使我的 kivy 应用程序真正工作，至少根据 kivy 文档。不过，感谢您的帮助！
有趣，我从来没有用过。

【解决方案1】：

好吧，我设法自己解决了我的问题，所以对于此后来到这里的任何人来说，问题出在这一行中的 .spec 文件（或至少在我的情况下）：

a.datas += [('./main.kv', '.')]
a.datas += [('./Resources', 'Resources')]

这里的解决方案是将您的数据实际放在Analysis 类的datas 变量中，而不是稍后添加它们，如下所示：

from kivy_deps import sdl2, glew

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


block_cipher = None


a = Analysis(['main.py'],
             pathex=['C:\\Users\\HP\\Desktop\\TPM-Kivy'],
             binaries=[],
             #put your data here instead of adding it in later
             datas=[('./main.kv', '.'), ('./Resources', 'Resources')], 
             hiddenimports=[],
             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, Tree('C:\\Users\\HP\\Desktop\\TPM-Kivy'),
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          *[Tree(p) for p in (sdl2.dep_bins + glew.dep_bins)],
          name='TPManager',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          upx_exclude=[],
          runtime_tmpdir=None,
          console=True , icon='GUIIcon.ico')
