使用Pyinstaller 2, PyQt4和Qt5创建OSX PyQt应用程序

Question

我正在尝试使用PyInstaller 2为OSX打包PyQt程序，其中PyQt4(4.10)是针对Qt 5.0.2(来自Git)构建的。下面的简单示例不起作用。

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/makepec .py生成的规范文件，并修改为添加BUNDLE类。

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'
        )

包装命令

> python pyinstaller.py --windowed hello.spec

在终端上直接运行二进制文件会在崩溃前给出如下输出:

$ ./dist/hello.app/Contents/MacOS/hello 
Hello
Failed to load platform plugin "cocoa". Available platforms are: 
Abort trap: 6

，这是堆栈跟踪:

问题似乎是它找不到libqcocoa。dylib插件。这并不奇怪，因为它没有打包。是这里的实际问题，我需要包括这个插件吗?如果是这样，它需要去哪里?我试过把它放在演示中。

Answer 1

libqcocoa的正确位置。dylib在Contents/MacOS/qt4_plugins/platforms:

extralibs = [("qt4_plugins/platforms/libqcocoa.dylib", "/path/to/libqcocoa.dylib", "BINARY")
             ]
coll = COLLECT(exe,
               a.binaries + extralibs,
               a.zipfiles,
               a.datas,
               strip=None,
               upx=False,
               name=os.path.join('dist', 'hello'))

应用程序现在启动，但对话框窗口从未出现。编辑:这是因为PyInstaller (v 2.0)在应用程序的Info.plist中添加了LSBackgroundOnly=true。

Answer 2

尝试添加(但为PyQt更改):

from PySide import QtCore, QtGui

至少这对我来说是有效的(PySide 1.1.1, Qt 4.8.1，最新的开发Pyinstaller, OSX 10.7.5，没有改变spec文件和——onefile——window参数给Pyinstaller)。如果没有这个代码片段，它也会崩溃。

我想这会引入更多的依赖项。
