FFmpeg -bash：ffmpeg：找不到命令

Question

好的，所以我在互联网上走来走去，想弄清楚我做错了什么...但是我却茫然无措。 我基本上是按照以下说明尝试在CENTOS 6.6专用服务器上安装FFmpeg ： https : //trac.ffmpeg.org/wiki/CompilationGuide/Centos

在整个过程中，一切似乎都进行得很好。 完成所有操作后，我按回车键输入“ ffmpeg”，并继续收到此极其丑陋的错误：

-bash：-bash ::找不到命令

我不是外壳专家，但是今天整天都在使用它，我可以说这意味着安装不正确。 因此，我尝试重新安装它，它告诉我所有软件包现在已经存在。 如果我正在做什么以及正在得到什么，请提供以下副本：

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

任何想法或帮助将不胜感激！

好的，在多加注意之后，我意识到有一个错误

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.

因此，我刚创建了/ tmp目录并运行了该命令：

export TMPDIR=$HOME/tmp

然后运行安装命令！
