在Ubuntu上从头开始重新安装VLC总是在错误的目录中寻找插件。

Question

我在Ubuntu14.04上安装了vlc 2.1.5，安装在/usr/bin/vlc中的"apt-get install vlc“中，运行良好

然后，我从源文件编译并安装了另一个版本的vlc (不记得确切的版本号)到"/usr/local/bin/“。

然后，我想回到原来的vlc 2.1.5和删除编译后的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

用"sudo rm -rf .“(我没有运行"make“，因为我安装后意外删除了源文件)

之后，我删除了vlc的第一个实例：

sudo apt-get purge vlc
sudo apt-get autoremove vlc

和删除的配置文件

sudo rm -rf ~/.config/vlc

此时，我认为我完全删除了两个vlc实例(可能是我弄错了)。然后我又从头开始安装了vlc：

sudo apt-get update
sudo apt-get install vlc

现在，当我运行"vlc -vv“时，我得到的是：

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"/usr/lib/vlc/plugins”。

如果我跑了

export VLC_PLUGIN_PATH=/usr/lib/vlc/plugins

然后我就会发现这个错误：

有人能帮我解决这个问题吗？

Answer 1

我再次下载源文件并运行"make“，它解决了我的问题。现在，在重新安装vlc之后，它将无错误地运行。
