Question

我一直在尝试编译一个使用PyQt5的QtWebEngine的应用程序。该应用程序按预期工作，但在编译时失败。我花了几天时间寻找解决方案，但到目前为止我没有运气。我从brew中安装了python并从它的网站下载了包。我还安装了PyQt5 form brew和pip3而没有任何运气。运行pyinstaller脚本后，我得到“找不到QtWebEngineProcess”错误。通过将QtWebEngineProcess.app文件复制到MacOS文件夹中来解决这个问题。随后我确保info.plist文件不是符号链接而是实际文件。之后，我将“org.qt-project.Qt.QtWebEngineCore”标志添加到主应用程序info.plist中的“CFBundleIdentifier”。这解决了找不到“QtWebEngineProcess”的问题，但它现在带来了下面所述的错误。我也将“icudtl.dat”复制到了MacOS文件夹中。我还尝试用框架本身重建依赖项，并确保我没有符号链接like stated here。我不熟悉install_name_tool所以我被困在那里。有任何想法吗？是否有人能够使用QtWebEngine编译pyqt应用程序？

这是我面临的错误：

使用this branch并添加一些custom patching后，它对我有用：

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):
            shutil.copytree(f, os.path.join(dest, f))
        else:
            shutil.copy(f, dest)
    # Link dependencies
    for lib in ['QtCore', 'QtWebEngineCore', 'QtQuick', 'QtQml', 'QtNetwork',
                'QtGui', 'QtWebChannel', 'QtPositioning']:
        dest = os.path.join(app_path, lib + '.framework', 'Versions', '5')
        os.makedirs(dest)
        os.symlink(os.path.join(os.pardir, os.pardir, os.pardir, 'Contents',
                                'MacOS', lib),
                   os.path.join(dest, lib))
