roscd returns: No such package <learning_tf2>

Hello, I am a beginner at ROS and following URDF tutorials, so i am at currently this part http://wiki.ros.org/tf2/Tutorials/Writing%20a%20tf2%20static%20broadcaster%20%28Python%29 (Writing a tf2 static broadcaster (Python))

so i have created the "learning_tf2 package and it exists. but when i write roscdlearningtf2 it returns roscd: No such package/stack 'learning_tf2' . I went through this question https://answers.ros.org/question/65950/roscd-returns-roscd-no-such-packagestack-package_name/ however even after following the steps given in answer i get the same error. SINCE i don't have enough points to upload an image, i would upload the content:

rahul@rahul:~$ source catkin_ws/devel/setup.bash

rahul@rahul:~$ catkincreatepkg learningtf2 tf2 tf2ros roscpp rospy turtlesimCreated file learning_tf2/package.xml

Hi @Rahulwashere,

Remember that, to have rosbash commands available you need to source your enviroment with:

source /opt/ros/noetic/setup.bash

Also take into account that roscd command will not find the package if you did not catkin_make and re-source the terminal.

HI, i tried it again by deleting the package and redo it, so first i wrote "source /opt/ros/kinetic/setup.bash then follow the command source catkin_ws/devel/setup.bash followed by the commands i wrote in the question. however the problem presists. i still get roscd learning_tf2:No such package/stack 'learning_tf2'. i did catkin make too, can you tell me how to resource the terminal, may be i am missing that

redid catkin make and sourced setup.bash
