有人可以帮助我吗？我是python的新手。
我想运行一个 Python 项目，它在树莓派零 W 中被证明是正确的，它上面的系统是 Debian 之类的 linux，我已经安装了 Python 2 和 python 3。
当我杀死上面的错误时，又出现了另一个错误，如下所示：
root@raspberrypi:/home/pi/Downloads/dejavu# python2 example.py ######## filename: mp3/Brad-Sucks--Total-Breakdown.mp3

有人遇到过类似的问题吗？
【问题讨论】：
-
请提供您的代码，以便我们为您提供帮助。
-
不需要代码，看起来没有“/home/pi/Downloads/dejavu/mp3/Brad-Suc ks--Total-Breakdown.mp3”这样的文件，我相信额外的空格是原因
-
git.oschina.net/leochan007/dejavu，你能得到这个网站的代码吗？
-
@k.biao 不，我们不能。请在此处发布相关代码摘录。
-
@ifconfig git.oschina.net/leochan007/dejavu 或 github.com/worldveil/dejavu 。这些是代码，我都运行它们，发生同样的错误。你可以尝试运行它吗？谢谢
