class 1: autoware_auto_create_pkg command not found error

I cannot create my own package using autoware_auto_create_pkg command.

I tried after source /opt/AutowareAuto/setup.bash in ade.

how can I fix this?

hayoung@ade:~/AutowareAuto (master % u=)$ source /opt/AutowareAuto/setup.bash
hayoung@ade:~/AutowareAuto (master % u=)$ autoware_auto_create_pkg
bash: autoware_auto_create_pkg: command not found
