解决ffmpeg问题

爬虫程序报错

File "/data/app/Anaconda/envs/yunjie/lib/python3.8/subprocess.py", line 1720, in _execute_child
    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'ffprobe'

根据报错提示分析出ffmpeg包安装并不完整，可卸载重装，如果还还不起作用，先安装第三方仓库，在安装ffmpeg，然后验证ffmpeg是否安装成功

#安装 EPEL（Extra Packages for Enterprise Linux）仓库：
sudo yum install epel-release -y

#安装 Nux Dextop 仓库
sudo rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
sudo rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm


#安装 FFmpeg 和相关开发包
sudo yum install ffmpeg ffmpeg-devel -y


#验证是否安装成功
ffmpeg -version
