没有在kivy论坛上得到回复,所以在这里尝试。
当我将教程pong代码编译为一个文件可执行文件时,我仍然必须将pong.kv文件包含在同一文件夹中才能运行。 否则,启动exe时会出现以下错误:
GL: EXT_framebuffer_object is supported [INFO ] [GL ] OpenGL version [INFO ] [GL ] OpenGL vendor [INFO ] [GL ] OpenGL renderer [INFO ] [GL ] OpenGL parsed version: 2, 1 [INFO ] [GL ] Shading version [INFO ] [GL ] Texture max size [INFO ] [GL ] Texture max units [INFO ] [Window ] auto add sdl2 input provider [INFO ] [Window ] virtual keyboard not allowed, single mode, not docked Traceback (most recent call last): File "", line 81, in File "c:\python34\lib\site-packages\kivy\app.py", line 802, in run root = self.build() File "", line 75, in build File "", line 20, in serveBall AttributeError: 'NoneType' object has no attribute 'center' main returned -1
如何让它作为一个可执行文件运行。这是我的pong.spec文件:
# -*- mode: python -*-
from kivy.deps import sdl2, glew
block_cipher = None
a = Analysis(['Code\main.py'],
pathex=['E:\\Development\\Pong'],
binaries=None,
datas=None,
hiddenimports=[],
hookspath=[],
runtime_hooks=[],
excludes=[],
win_no_prefer_redirects=False,
win_private_assemblies=False,
cipher=block_cipher)
pyz = PYZ(a.pure, a.zipped_data,
cipher=block_cipher)
a.datas += [('Code\pong.kv', 'E:\\Development\\Pong\Code\pong.kv', 'DATA')]
exe = EXE(pyz,Tree('Code'),
a.scripts,
a.binaries,
a.zipfiles,
a.datas,
*[Tree(p) for p in (sdl2.dep_bins + glew.dep_bins)],
name='pong',
debug=False,
strip=False,
upx=True,
console=True , icon='pong.ico')
请注意,我尝试将pong.kv包含在数据列表中,但这并没有帮助。
谢谢, -Raj

根据KeyWeeUsr(Bundling data files with PyInstaller和Using PyInstaller to make EXEs from Python scripts)提供的链接并将其与Kivy的资源路径方法相结合,这是一个可行的解决方案。我觉得它有点粗糙,因为它使用SYS._MEIPASS(我更喜欢公共API)并且需要在Python代码中添加代码片段。但是,该解决方案适用于Windows和Mac,因此将共享。
假设我有以下代码层次结构:
MyCode/ MyApp.py (This is the main program) myapp.kv (This is the associated kv file) MyData/ (This is where data is located that the app uses) myapp.icns (e.g. icon file for mac) myapp.ico (e.g. icon file for windows) Build/ mac/ myapp.spec (spec file to build on mac platform) pc/ myapp.spec (spec file to build on windows platform) MyHiddenImports/ (Folder containing python files for hidden imports)
我在示例中添加了一个MyHiddenImports文件夹,以防您的代码在运行时也将包含python代码的另一个文件夹附加到sys.path。
在MyApp.py中添加以下内容:
def resourcePath():
'''Returns path containing content - either locally or in pyinstaller tmp file'''
if hasattr(sys, '_MEIPASS'):
return os.path.join(sys._MEIPASS)
return os.path.join(os.path.abspath("."))
if __name__ == '__main__':
kivy.resources.resource_add_path(resourcePath()) # add this line
my_app = MyApp()
resources_add_path()告诉Kivy在哪里查找data / .kv文件。例如,在Mac上,当运行pyinstaller应用程序时,它指向/ private / var / folders / 80 / y766cxq10fb_794019j7qgnh0000gn / T / _MEI25602,在Windows中,它指向c:\ users \ raj \ AppData \ Local \ Temp_MEI64zTut(这些文件夹在退出应用程序后被删除,并在再次启动时创建另一个名称)。
我使用以下命令创建了初始Mac模板规范文件:
pyinstaller --onefile -y --clean --windowed --name myapp --icon = .. / .. / Code / Data / myapp.icns --exclude-module _tkinter --exclude-module Tkinter - exclude-module enchant --exclude-module twisted ../../ Code / MyApp.py
以下是经过修改的Mac OS规范文件:
# -*- mode: python -*-
block_cipher = None
a = Analysis(['../../Code/MyApp.py'],
pathex=['/Users/raj/Development/Build/mac',
'../../MyHiddenImports'],
binaries=None,
datas=None,
hiddenimports=['MyHiddenImports'],
hookspath=[],
runtime_hooks=[],
excludes=['_tkinter', 'Tkinter', 'enchant', 'twisted'],
win_no_prefer_redirects=False,
win_private_assemblies=False,
cipher=block_cipher)
pyz = PYZ(a.pure, a.zipped_data,
cipher=block_cipher)
a.datas += [('myapp.kv', '../../MyCode/my.kv', 'DATA')]
exe = EXE(pyz, Tree('../../Code/Data', 'Data'),
a.scripts,
a.binaries,
a.zipfiles,
a.datas,
name='myapp',
debug=False,
strip=False,
upx=True,
console=False , icon='../../Code/Data/myapp.icns')
app = BUNDLE(exe,
name='myapp.app',
icon='../../Code/Data/myapp.icns',
bundle_identifier=None)
注意事项:我向pathex添加了隐藏的导入路径,并在hiddenimports中引用了包。我将myapp.kv文件附加到a.datas,以便将其复制到应用程序中。在EXE中,我添加了数据树。我包含了前缀参数,因为我希望将Data文件夹复制到应用程序中(而不是让孩子们坐在根级别)。
要编译代码以创建应用程序并将其放入dmg文件,我有一个make-myapp脚本执行以下操作:
pyinstaller -y --clean --windowed myapp.spec pushd dist hdiutil create ./myapp.dmg -srcfolder myapp.app -ov popd cp ./dist/myapp.dmg .
同样,这里是windows spec文件:
# -*- mode: python -*-
from kivy.deps import sdl2, glew
block_cipher = None
a = Analysis(['..\\..\\Code\\Cobbler.py'],
pathex=['E:\\Development\\MyApp\\Build\\pc',
'..\\..\\MyHiddenImports'],
binaries=None,
datas=None,
hiddenimports=['MyHiddenImports'],
hookspath=[],
runtime_hooks=[],
excludes=[],
win_no_prefer_redirects=False,
win_private_assemblies=False,
cipher=block_cipher)
pyz = PYZ(a.pure, a.zipped_data,
cipher=block_cipher)
a.datas += [('myapp.kv', '../../Code/myapp.kv', 'DATA')]
exe = EXE(pyz, Tree('..\\..\\Code\\Data','Data'),
a.scripts,
a.binaries,
a.zipfiles,
a.datas,
*[Tree(p) for p in (sdl2.dep_bins + glew.dep_bins)],
name='myapp',
debug=False,
strip=False,
upx=True,
console=False, icon='..\\..\\Code\\Data\\myapp.ico' )
编译windows app:
python -m PyInstaller myapp.spec

如果您不关心代码长度,那么使用Builder.load_string
在.py文件中加载kv数据怎么样?这样整个代码都保存在python脚本中,这可能有助于将其编译为.exe。
