rospack can't find package created with catkin_create_package

I'm working through the beginner tutorials using ROS Hydro and I attempted to create my first package by running:

$ catkin_create_pkg beginner_tutorials std_msgs rospy roscpp

This produced no errors and appears to have created the associated files and folders. However, using rospack to find the newly created package doesn't work:

$ rospack find beginner_tutorials 
[rospack] Error: stack/package beginner_tutorials not found

What am I missing?

Did you create the package in your ROS_PACKAGE_PATH? Try also to run 'rospack profile' before running the rospack find command.

What do you mean by " did you create the package in your ROS_PACKAGE_PATH"?

I had a similar problem with a package i created using the catkin_create_pkg tool. here's what i did:

erase all the folders and files in your catkin_ws except "src"
build your catkin_ws (catkin_make or catkin build whatever you use)
go to ~/catkin_ws/devel and find your setup.bash file (the point is to just make sure you know the path to this file)
go to your home folder, ctr+h to see hidden files, open the .bashrc file and at the end add "source [path to the setup file from step 3]
close your terminal, open it again and now your packages in the catkin_ws/src should be registered.

hope i helped somebody

thanks a lot... It worked for me... !! Is it necessary to always put the path as a source in the .bashrc ? for each package i'll create

ros sometime does not recognise newly created packages.

Solution: go to <path-to-catkin-ws> source devel/setup.bash

close terminal and open new terminal. Now you would be able to find that package.

Closing terminal after sourcing is pointless because the source will be lost. @Tirjen is right, rospack profile should do the work if the package is already sourced.
