MacOS 10.14 Python 3.7.1 PyInstaller个最新版本于2019年9月24日从pip install https://github.com/pyinstaller/pyinstaller/archive/develop.zip下载我正在尝试使用PyQt5和PyInstaller构建应用。我可以使用以下小脚本（脚本1 ）成功地完成此操作：在确定了该脚本所在的目录之后，我只运行了PyInstaller script.py。然后，它构建了该应用程序，我可以在新创建的子目录path/to/script/dist/script/中找到可执行文件。在此目录中，有一个可执行文件，您可以双击并运行该应用程序。然后，我尝试使用更大的脚本（脚本2 ，错误消息称为image_viewer_24_02_2019.py）执行相同的操作，该脚本找到了there。然后，我尝试运行可执行文件（在path/to/script/dist/script/中），但收到以下错误消息。构建脚本2 时，问题的根源是什么？
请注意，使用pip install https://github.com/pyinstaller/pyinstaller/archive/develop.zip安装最新版本后，问题仍然存在
依次为：脚本1 （可以成功构建），脚本2 （无法构建）及其错误消息。 >：
