I apologize, I don't have much experience with Linux. So I have ruby installed on my machine and I'm trying to install rails. When I do gem install rails I get a proper response
Successfully installed rails-6.0.3.2 1 gem installed But when I do rails --version it returns the following:
bash: /usr/lib/command-not-found: /usr/bin/python3: bad interpreter: No such file or directory What can be the issue here?
My machine is running on Zorin OS. By the way here's some more information: temp-user@Lenovo-IdeaPad-S145-5:~$ ls -l /usr/bin | grep python

/usr/lib/command-not-found is a piece of code that tries to make suggestions when the command you typed cannot be found (spelling errors, or suggests the installation of package that provide the command). It happens to be written in Python3, and Python3 may not be installed on your system (even though it's kind of mandatory on recent Linux distros...).
But you get this error because the rails command cannot be found. Since you ran the installation as a user space, rails is likely in some user directory that you have to add to your PATH (edit your ~/.profile). You can use gem list -d to find the directory.
apt install python fixed it for me..
