Question

只需安装凉亭并得到：

$ curl -sSL http://get.gazebosim.org | sh
...
$ gazebo
Error [Param.cc:404] Invalid argument. Unable to set value [.1 ] for key[near].
Exception [Param.cc:57] SDF ASSERTION                     
Invalid parameter
In function       : Param
Assert expression : this->ValueFromString(_default)

如何解决？
