我在/ usr / bin / vlc中的“ apt-get install vlc”安装了Ubuntu 14.04上的vlc 2.1.5，它工作正常
然后，我将源文件中的vlc的另一个版本（不记得确切的版本号）编译并安装到“ / usr / local / bin /”中。
然后，我想回到原始vlc 2.1.5并删除已编译的vlc。为此，我找到了第二个vlc实例的所有文件/文件夹，
sudo find /usr/local -iname vlc
并通过“ sudo rm -rf ...”手动将其删除（我没有运行“ make uninstall”，因为安装后不小心删除了源文件）
之后，我删除了vlc的第一个实例：
sudo apt-get purge vlc
sudo apt-get autoremove vlc
和已删除的配置文件
sudo rm -rf ~/.config/vlc
在这一点上，我认为我已经完全删除了两个vlc实例（也许我弄错了）。然后我再次从头开始安装vlc：
sudo apt-get update
sudo apt-get install vlc
现在，当我运行“ vlc -vv”时，我得到：

我不知道为什么，但是新的vlc安装会在“ / usr / local / lib / vlc / plugins”文件夹中查找插件，而不是在“ / usr / lib / vlc / plugins”文件夹中查找插件
如果我跑步
export VLC_PLUGIN_PATH=/usr/lib/vlc/plugins
然后我得到这个错误：

我猜想，当您编译并安装vlc版本时，它安装了一些用找不到的文件sudo find /usr/local -iname vlc，可能使用了不同的名称。如果他们仍然在某个地方，可能会导致您的问题。如果您要重新下载相同的文件，则可能会有一个“卸载”功能，或者您可以仔细观察它安装了哪些文件并将其删除...
或者，仅链接或绑定安装/usr/local/lib/vlc/plugins即可/usr/lib/vlc/plugins解决当前问题。
仅供参考，我的~/.config/vlc/vlcrc文件中有此文件，但我认为它并没有真正的关系
# Use a plugins cache (boolean)
#plugins-cache=1
