我找到了解决方案。您需要检查应用程序是作为脚本还是作为冻结的exe运行:
import os
import sys
config_name = 'myapp.cfg'
# determine if application is a script file or frozen exe
if getattr(sys, 'frozen', False):
application_path = os.path.dirname(sys.executable)
elif __file__:
application_path = os.path.dirname(__file__)
config_path = os.path.join(application_path, config_name)
