用QtWebEngine編譯PyQt5應用程序

我一直在嘗試編譯一個使用PyQt5中的QtWebEngine的應用程序。該應用程序按預期工作，但在編譯時失敗。我花了幾天尋找解決方案，但到目前爲止我沒有運氣。我已經安裝了Python的brew和下載它的網站包。我也沒有任何運氣安裝了PyQt5 brew和pip3。運行pyinstaller腳本後，我得到「無法找到QtWebEngineProcess」錯誤。這是通過將QtWebEngineProcess.app文件複製到MacOS文件夾中解決的。接下來，我確信info.plist文件不是符號鏈接，而是實際的文件。之後，我將「org.qt-project.Qt.QtWebEngineCore」標誌添加到主應用程序info.plist中的「CFBundleIdentifier」中。這解決了找不到「QtWebEngineProcess」的問題，但它現在帶來了下面所述的錯誤。我也將「icudtl.dat」複製到MacOS文件夾中。我也嘗試重建與框架本身的依賴關係，並確保我沒有符號鏈接like stated here。我不熟悉install_name_tool，所以我被困在那裏。有任何想法嗎？任何人都可以使用QtWebEngine編譯pyqt應用程序嗎？用QtWebEngine編譯PyQt5應用程序

這裏是我所面對的錯誤：

它了一些問題與QtWebEngine。我相信存在補丁來修復這個bug。可以使用this branch並加入一些custom patching後看到其他信息在https://github.com/pyinstaller/pyinstaller/issues/2566

它的工作對我來說：

def patch_osx_app(): 
    """Patch .app to copy missing data and link some libs. 
    See https://github.com/pyinstaller/pyinstaller/issues/2276 
    """ 
    app_path = os.path.join('dist', 'qutebrowser.app') 
    qtwe_core_dir = os.path.join('.tox', 'pyinstaller', 'lib', 'python3.6', 
           'site-packages', 'PyQt5', 'Qt', 'lib', 
           'QtWebengineCore.framework') 
    # Copy QtWebEngineProcess.app 
    proc_app = 'QtWebEngineProcess.app' 
    shutil.copytree(os.path.join(qtwe_core_dir, 'Helpers', proc_app), 
        os.path.join(app_path, 'Contents', 'MacOS', proc_app)) 
    # Copy resources 
    for f in glob.glob(os.path.join(qtwe_core_dir, 'Resources', '*')): 
     dest = os.path.join(app_path, 'Contents', 'Resources') 
     if os.path.isdir(f):

     else:
