Question

我需要在MacOS中显示通知。只需使用python运行脚本即可显示通知。但每当我使用Pyinstaller打包脚本时，我都会收到以下错误。好像Pyinstaller在使用Mac通知时遇到了一些问题。我也尝试过使用pync (Python binding for terminal notifier)。在所有情况下，只需运行应用程序python notify.py即可，但使用Pyinstaller冻结脚本似乎不起作用。

    Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/Library/Python/2.7/site-packages/PyInstaller-2.1-py2.7.egg/PyInstaller/loader/pyi_importers.py", line 270, in load_module

我使用以下Python脚本来显示通知

import Foundation
import objc

NSUserNotification = objc.lookUpClass('NSUserNotification')
NSUserNotificationCenter = objc.lookUpClass('NSUserNotificationCenter')

notification = NSUserNotification.alloc().init()
notification.setTitle_("TestTitle")
notification.setInformativeText_("This is sample text")
center = NSUserNotificationCenter.defaultUserNotificationCenter()
center.deliverNotification_(notification)

我有类似的问题，这就是我的工作方式。您不需要使用Foundation来解决Pyinstaller的问题（不确定为什么会导致问题）并且不会在代码的其他地方使用。

import objc

NSUserNotification = objc.lookUpClass('NSUserNotification')
NSUserNotificationCenter = objc.lookUpClass('NSUserNotificationCenter')

notification = NSUserNotification.alloc().init()
notification.setTitle_("TestTitle")
notification.setInformativeText_("This is sample text")
center = NSUserNotificationCenter.defaultUserNotificationCenter()
center.deliverNotification_(notification)

此时，它可能会引发一些错误或通知不会显示。 只需将CFBundleIdentifier密钥添加到pyinstaller生成的info.plist文件中。

Pyinstaller错误无法对未注册的加载程序类型（MacOS）执行此操作
