使用Pyinstaller 2，PyQt4和Qt5创建OSX PyQt应用 [英] Creating an OSX PyQt app using Pyinstaller 2, PyQt4 and Qt5

问题描述

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.

I am trying to package a PyQt program for OSX using PyInstaller 2, where PyQt4 (4.10) has been built against Qt 5.0.2 (from Git). The following simple example doesn't work.

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生成并修改为添加BUNDLE类的规范文件.

Spec file generated using pyinstaller-2.0/utils/MakeSpec.py and modified to add the BUNDLE class.

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

> 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:

Running the binary directly from the terminal gives this output before it crashes:

$ ./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.

The issue appears to be that it can't find the libqcocoa.dylib plugin. This is not surprising as it is not packaged. Is that the actual issue here and do I need to include this plugin? If so where does it need to go? I have tried putting it in demo.app/Contents/plugins but that doesn't help.

推荐答案

放置libqcocoa.dylib的正确位置在Contents/MacOS/qt4_plugins/platforms中:

The right place to put libqcocoa.dylib is in 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，但对话框窗口永不出现.这是因为PyInstaller(v 2.0)将LSBackgroundOnly = true添加到了应用程序Info.plist.删除此选项将显示窗口.

The app now starts but the dialog window never appears. This is because PyInstaller (v 2.0) adds LSBackgroundOnly=true to the apps Info.plist. Removing this allows the window to show.
