关于macOS：使用Pyinstaller 2，PyQt4和Qt5创建OSX PyQt应用

Creating an OSX PyQt app using Pyinstaller 2, PyQt4 and Qt5

我正在尝试使用PyInstaller 2打包OSX的PyQt程序，其中已针对Qt 5.0.2(来自Git)构建了PyQt4(4.10)。以下简单示例不起作用。

import sys
from PyQt4.QtGui import QApplication, QMessageBox

def main():
print"Hello"
a = QApplication(sys.argv)
m = QMessageBox(QMessageBox.Information,"Title","Hello")
m.exec_()

if __name__=="__main__":
main()

使用pyinstaller-2.0 / utils / MakeSpec.py生成并修改以添加BUNDLE类的规范文件。

a = Analysis(['hello.py'],
pathex=['/Users/glenn/rp/src/demo'],
hiddenimports=[],
hookspath=None)

pyz = PYZ(a.pure)

exe = EXE(pyz,
a.scripts,
exclude_binaries=1,
name=os.path.join('build/pyi.darwin/hello', 'hello'),
debug=False,
strip=None,
upx=True,
console=False )

coll = COLLECT(exe,
a.binaries,
a.zipfiles,
a.datas,
strip=None,
upx=True,
name=os.path.join('dist', 'hello'))

app = BUNDLE(coll,
name=os.path.join('dist', 'hello.app'),
appname="Hello",
version = '0.1'
)

打包命令

1	> python pyinstaller.py --windowed hello.spec

直接从终端运行二进制文件会在崩溃之前提供此输出：

问题似乎是找不到libqcocoa.dylib插件。这并不奇怪，因为它没有包装。这是这里的实际问题吗，我需要包括这个插件吗？如果是这样，它需要去哪里？我尝试将其放在demo.app/Contents/plugins中，但这无济于事。
