So I have made this simple Password Manager in Python 3.8 using PyQt5, and I have been using the 'py2app' module to create a standalone application of this program. However, when I execute my app (both from the terminal and the finder), I get a simple popup saying "keysafe Error". My code is executing just fine and has no errors. I can't seem to figure out the problem here. If it helps, I get this message in my macOS logs:
Mar 16 10:29:01 my-MacBook-Air com.apple.xpc.launchd[1]: Coalition Cache Hit: app<application.org.pythonmac.unspecified.keysafe.5854321.5857989(501)> [78372] Mar 16 10:29:01 my-MacBook-Air keysafe[16934]: keysafe Error Mar 16 10:29:02 my-MacBook-Air com.apple.xpc.launchd[1] (application.org.pythonmac.unspecified.keysafe.5854321.5857989[16934]): Service exited with abnormal code: 255 I have also been using the following terminal commands to generate my standalone application using py2app:
cd <path_to_my_python_script> py2applet --make-setup keysafe.py python3 setup.py py2app I really can't figure out what to do, and all help is appreciated! Thanks in advance!
Update: If you go to your application and right-click it in the finder, it will give you a menu option. Then, click Show Package Contents. After that, navigate to the Contents > MacOS and you will see a Unix Executable File of your python script. Run the file, and you can locate what your error is.
After trying this out, I got an error with problems about the function I had named exit in my password manager. I thought that the keyword exit might conflict with some sort of MacOS Setting, and changed the function name to exit_. After creating another Standalone Application with my updated script, I ran the Unix executable again and got a new error (so the exit keyword was fixed). My new error is:
