Command 'rails' not found but it used to work perfectly...

Rails • Asked by Damian Nelwep

Hello everyone,
I'm having some issue I really don't know why... It is the second time I get this but, after working on a Rails project without any problem, I try to get back to it and it tells me :

Command 'rails' not found, but can be installed with:

sudo apt install ruby-railties

But I installed Rails already and as I said, it worked perfectly... So anyone could help and tell me how and why this could happend.

Thank you


By the way I also tried

gem update bundler
Updating installed gems
Updating bundler
Fetching: bundler-2.0.1.gem (100%)
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /var/lib/gems/2.5.0 directory.

I could do sudo but I think it's not normal that I have to do it this way...


Yeah, sounds like you don't have rbenv in your PATH env var.

And you're right, never use sudo because you'll end up with permissions errors.


Ok so the best thing to do may be to remove any trace of rbenv ..?

In the end the main problem was just because I used an other Terminal version (Terminator in place of the classic one) but anyways I don't know if this is a 'normal' issue...
