Ich versuche, Ruby auf meinem Ubuntu 14.04-Rechner neu zu installieren, bin mir aber nicht sicher, wie ich meine PATH-Variable oder andere Dinge einrichten soll. Wenn ich es als normaler Benutzer versuche, erhalte ich alle möglichen Fehlermeldungen wegen verweigerter Berechtigung ...

aber wenn ich dann versuche, als sudo zu installieren, erhalte ich den Fehler "Befehl nicht gefunden"
myuser@myproject:~$ sudo rvm reinstall ruby-2.4.0
sudo: rvm: command not found
Wie richte ich mein Sudo ein, damit es meine ausführbare RVM-Datei genauso findet wie mein normaler Benutzer?
Antwort1
Versuchen sudo -E rvm reinstall ruby-2.4.0.
Aus man sudo:
-E, --preserve-env
