Problem with Gazebo std::bad_alloc

I installed Gazebo a couple weeks ago along with ros-kinetics on ubuntu 16.04. Until yesterday Gazebo would launch with no problems, I have hardly used it and now when I try to launch it as an application it appears for a split second and then disappears, while if I try to launch it with the terminal it says

"terminate called after throwing an instance of 'std::bad_alloc'

what(): std::bad_alloc

I just installed ubuntu and have never used this kind of stuff so I have no idea of what the problem could be, i tried searching for this problem but most people are having this problem as a C++ problem. Yesterday during class we wrote some C++ code, but I didn't link it to Gazebo. I don't know what to do and I'm afraid I might to some mistake while trying to fix it.

Thank you in advance

Instead of just using the gazebo command, try doing the following: 1) open a terminal, and run the command "roscore" 2) open another terminal and now run "rosrun gazebo_ros gazebo" Does doing this give you different results?

I tried it and it says "[rospack] Error: package 'gazebo_ros' not found" This morning I tried to uninstall and reinstall gazebo with sudo apt-get remove gazebo7 and later sudo apt-get install gazebo7, could that be the problem I am facing right now?

Try running: "sudo apt-get install ros-kinetic-gazebo-ros-pkgs" and after that try the instructions from my first comment again.

I tried that and now it gives me this: [ INFO] [1521635182.476361394]: Finished loading Gazebo ROS API Plugin.

So it goes back to the std::bad_alloc error. I've encountered it a few times but it's usually resolved when i simply run Gazebo again. From quickly googling, std::bad_alloc is caused when you run out of memory. Unfortunately I'm not sure if I know how to help you resolve this problem.
