Pyinstaller 难以通过 Kivy 构建 FileChooserListView

Question

我正在尝试集成 kivy 中包含的文件选择器模块，以允许用户通过 FileChooserListView 获取输入文件的文件字符串，但是当通过 pyinstaller 构建应用程序时，应用程序无法打开。有人碰巧知道问题是什么吗？这是一个示例代码：在 pycharm 中运行良好，但在 pyinstaller 构建时无法打开。

from os.path import exists
from threading import Thread
from sys import exit
from kivy.app import App
from kivy.uix.gridlayout import GridLayout
from kivy.uix.popup import Popup
from kivy.uix.button import Button
from kivy.lang import Builder
from os.path import sep, expanduser, dirname, splitext
from kivy.uix.filechooser import FileChooserListView

KV = '''

<MetaLevel>:
    rows: 2
    cols: 1
    Label:
        text: 'test text'
    Button:
        text: 'test button'
        on_press: root.popup()    

<file_popup>:
    file_chooser: file_chooser
    GridLayout:
        rows:1
        cols:1
        FileChooserListView:
            id: file_chooser
            path: r'C:\\Users'
            on_submit: root.printer()
'''

Builder.load_string(KV)

class MetaLevel(GridLayout):
    def popup(self):
        App.get_running_app().file_popup.open()

class file_popup(Popup):
    def printer(self):
        print(self.file_chooser.path)
        App.get_running_app().file_popup.dismiss()

class Cruncher(App):
    def build(self):
        self.file_popup = file_popup()
        return MetaLevel()


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

检查以确保您已安装库：
pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew

我确实让您的脚本成功构建，经过一番挖掘，它看起来像 win32file 尤其是 win32timezone 是一些隐藏的导入。

设置：
C:/
..温度/
....测试/
......test.py ......TEST.spec

TEST.spec文件：

from kivy_deps import sdl2, glew

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

block_cipher = None


a = Analysis(['C:/Temp/Test/test.py'],
             binaries=[],
             datas=[],
             hiddenimports=['win32file','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='TEST',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          console=False)
coll = COLLECT(exe, Tree('C:\\Temp\\Test\\'),
               a.binaries,
               a.zipfiles,
               a.datas,
               *[Tree(p) for p in (sdl2.dep_bins + glew.dep_bins)],
               strip=False,
               upx=True,
               name='TEST')

然后运行pyinstaller C:/Temp/Test/TEST.spec

如果你想要--onefile（我通常会这样做）：

TEST.spec文件：

from kivy_deps import sdl2, glew

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

block_cipher = None


a = Analysis(['C:/Temp/Test/test.py'],
             binaries=[],
             datas=[],
             hiddenimports=['win32file','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,
          a.binaries,
          a.zipfiles,
          a.datas,
          *[Tree(p) for p in (sdl2.dep_bins + glew.dep_bins)],
          [],
          name='TEST',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          runtime_tmpdir=None,
          console=False)
