Python 消息无法执行脚本

我编写了一个将docx转换为pdf的脚本

我用tkinter做了一个简单的表单

当我尝试使用以下命令生成exe文件时：

pyinstaller --onefile converter.py 

pyinstaller --noconsole converter.py

我还尝试了以下命令：

pyinstaller --onefile converter.py 

pyinstaller --noconsole converter.py

执行脚本转换器失败时出现错误

        for file in files:
            convert(file, str(os.path.dirname(file)))
        showinfo('Done', 'Files converted')

    button = tk.Button(win, text='Select', width=30, command=openfile)
