FileNotFoundError: [Errno 2] No such file or directory: ‘ffprobe‘: ‘ffprobe‘

在处理音频文件的时候，对数据预处理时的报错：

我先是按照网上的方法先后进行 pip install ffprobe、pip install ffmpeg 后仍报错，最后在这个博主的博文找到了解决办法https://blog.csdn.net/roxxo/article/details/108663833

先：sudo apt-get update ，然后再sudo apt-get install ffmpeg，问题就解决了。【我的要加sudo，否则权限不够】
