FFmpeg -bash: ffmpeg: 找不到命令

Question

好的，所以我在互联网上走来走去，试图找出我做错了什么……但我却一头雾水。我基本上是按照此处的说明在我的 CENTOS 6.6 专用服务器上安装 FFmpeg：https://trac.ffmpeg.org/wiki/CompilationGuide/Centos

整个过程似乎一切都很顺利。全部完成后，我输入 "ffmpeg" 回车并继续收到这个极其丑陋的错误：

-bash: -bash:: command not found

我不是一个 shell 人，但今天整天都在使用它，我可以说这意味着它没有正确安装。所以，我尝试重新安装它，它告诉我所有的包现在都已经存在了……。这是一份副本，如果我在做什么和我得到什么：

root@server1 [~]# ffmpeg -version
-bash: ffmpeg: command not found

root@server1 [~]# yum install autoconf automake gcc gcc-c++ git libtool make nasm pkgconfig zlib-devel

Nothing to do

非常感谢任何想法或帮助！

好的，仔细一看，发现有错误

Unable to create and execute files in /tmp.  Set the TMPDIR environment
variable to another directory and make sure that it is not mounted noexec.
Sanity test failed.

所以，我刚刚制作了 /tmp 目录和运行这个：

export TMPDIR=$HOME/tmp

然后运行安装命令！

FFmpeg -bash: ffmpeg: 找不到命令

FFmpeg -bash: ffmpeg: command not found

linux

shell

ffmpeg

centos
