Warning message can't load world into gazebo

[NamTruongTran0]

Hi,

first i would like to thank you for your amazing work. I really appreciate it ;)

I want to load directly into Gazebo (without ROS)

export GAZEBO_MODEL_PATH=`pwd`/models
gazebo worlds/bookstore.world

Gazebo open up but the world is not loading.

I getting this message in the terminal:

Warning [parser.cc:833] XML Attribute[version] in element[sdf] not defined in SDF, ignoring.
