NodeJS не найден после установки

У меня есть эта программа, которая нуждается в работе nodejs. Поэтому, когда я устанавливаю nodejs и проверяю его, он не работает. Это именно то, что я сделал:

    multiplemark@multiplemark-OptiPlex-GX280:~$ sudo -s
    [sudo] password for multiplemark: 
    root@multiplemark-OptiPlex-GX280:~# apt-get install nodejs && npm
