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

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。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生成的spec文件,并进行修改以添加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

直接从终端运行二进制文件会在崩溃之前提供此输出:

$ ./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:

问题似乎是找不到libqcocoa.dylib插件。这并不奇怪,因为它没有打包。这是实际问题吗?我需要包含这个插件吗?如果是这样,它需要去哪里?我已经尝试将它放在demo.app/Contents/plugins中,但这没有帮助。

答案 0 :(得分:3)

放置libqcocoa.dylib的正确位置在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永远不会出现。编辑:这是因为PyInstaller(v 2.0)将LSBackgroundOnly = true添加到应用程序Info.plist。删除它允许窗口显示。

答案 1 :(得分:1)

尝试添加(但为PyQt更改):

from PySide import QtCore, QtGui

至少这对我有用(PySide 1.1.1,Qt 4.8.1,最新的dev Pyinstaller,OSX 10.7.5,没有对spec文件进行更改,而--onefile - 对pyinstaller的参数也是如此。)而且没有这个片段,它也为我崩溃。

我认为这会带来更多的依赖关系。
