Existem dois problemas relacionados no Github ( aqui e aqui ). Aparentemente, você deve configurar o caminho completo em jupyterhub_config.py usando
c.Spawner.cmd = ['fullpath-to/jupyterhub-singleuser']
Estou tentando executar o jupyterhub com vários usuários da AWS, mas recebo um erro.
Eu uso o comando ubuntu@ip-172-31-23-74:~$ sudo /home/ubuntu/.local/bin/jupyterhub
e este é o erro que recebo quando tento logar com um dos usuários.
