問題はどちらか、この行に

/usr/bin/env: node: No such file or directory

であるあなたはnodejsがインストールされていないか、それが$PATHではないように見えます。 jupyterhubを実行するにはnodejs/npmが必要であることに注意してください。あなただけの詳細はthe JupyterHub GitHub pageとdocsを参照してください

sudo apt-get install npm nodejs-legacy

を実行することができますので、あなたには、いくつかのLinuxディストリビューションを実行しているようはに見えます。
