解决Failed to load module canberra-gtk-module错误

在Ubuntu环境里，运行程序时，报错：

1	Gtk-Message: 09:10:26.571: Failed to load module "canberra-gtk-module"

查看一下模块位置

1 2	locate libcanberra-gtk-module /usr/lib/x86_64-linux-gnu/gtk-3.0/modules/libcanberra-gtk-module.so

发现已经安装了，却加载不了。

重新安装一下吧。

sudo apt-get install libcanberra-gtk-module

安装成功，再次启动程序，就不会报错了。
