PyInstaller exe 文件不会创建日志文件

Question

I'm trying to make my scripts executable so I can send it to my colleague. I'm using PyInstaller .

pyinstaller --onefile main.py

Which creates two folders. When I open dist/main.exe, something is wrong but I don't know what because it doesn't create a log file. I can't figure out why. When I run main.py , the log file is created immediately.

Could you check it out?

As you froze the application the File may be located under sys._MEIPASS

Here is a little example I tested in my application:

 if hasattr(sys, "_MEIPASS"):
            base_dir = os.path.join(sys._MEIPASS)
            print(base_dir)
            print(sys.argv[0])
