Python ntpath.py上的特殊错误
我正在尝试在Windows7上的VLCPlayer上编写一个类似于包装器的东西,这样它就可以通过击键加载文件夹中的下一个和上一个文件。我在其中所做的是,我将一个filepath作为参数,创建一个vlc类的实例,并使用pyHook扫描键,当检测到特定的击键时,调用实例上的play_next和play_prev方法。这些方法的工作原理是杀死最后一个进程,并用get_new_file方法找到的下一个文件生成新的vlc。它先工作几次,然后给出特殊的错误Python ntpath.py上的特殊错误,python,windows-7,path,subprocess,Python,Windows 7,Path,Subprocess,我正在尝试在Windows7上的VLCPlayer上编写一个类似于包装器的东西,这样它就可以通过击键加载文件夹中的下一个和上一个文件。我在其中所做的是,我将一个filepath作为参数,创建一个vlc类的实例,并使用pyHook扫描键,当检测到特定的击键时,调用实例上的play_next和play_prev方法。这些方法的工作原理是杀死最后一个进程,并用get_new_file方法找到的下一个文件生成新的vlc。它先工作几次,然后给出特殊的错误 None None Traceback

我还将vlc工作卸载到另一个线程,因为pyHook对子进程的处理不好。
