ytviewcommand not found

hi. i installed this project today for curiocity but not worked well. i think i installed correctly because i can see commands when i run this code "./build/libs/ytviewbot". i tried this
`root@ip-10-0-0-9:~/youtube/ytviewbot# ytviewbot -w 10 https://www.youtube.com/watch?v=lol
[1] 28687
root@ip-10-0-0-9:~/youtube/ytviewbot# ytviewbot: command not found`
