PyInstaller exe 文件不會創建日志文件

Question

我正在嘗試使我的腳本可執行，以便我可以將其發送給我的同事。 我正在使用PyInstaller 。

pyinstaller --onefile main.py

這會創建兩個文件夾。 當我打開 dist/main.exe 時，出了點問題，但我不知道是什么，因為它沒有創建日志文件。 我不明白為什么。 當我運行main.py ，會立即創建日志文件。

你能檢查一下嗎？

當您凍結應用程序時，文件可能位於sys._MEIPASS

這是我在我的應用程序中測試的一個小例子：

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