原因

Gazebo try to collect models from http://gazebosim.org/models but there 's something wrong... the folder ~/.gazebo/models does not exist and Gazebo simulator can not start.
解决方式

运行
wget -r -R "index\.html*" "http://models.gazebosim.org" --reject=tar.gz

Got all models from gazebosim and copy them into ~/.gazebo/models folder and everything will be ok.
