I just downloaded an app code from github and when I am trying to run the command rails s, I am getting this error –
The program 'rails' can be found in the following packages:
* rails
* ruby-railties-3.2
This is specific to this app only, can someone tell me how to fix this ? I am using RVM
Not really sure what exactly your problem is. If you use rvm and have installed Rails with it, you may have to use
(version number may depend on your installation). Then you may or may have not a gemset with this. So:
should install Rails gem in this gemset. Maybe use
or just manually install the Rails gem. But this would partially depend on the Rails version expected by the app. There are other options, but this should mostly work.
For setting a version permanently you can use:
For this to work you must have something like this:
in your ~/.bash_profile.
In addition you can have something like a .rvm folder in your project where you can set rvm options on a project level if you need to switch between versins often (didn’t use this myself, but there should be docs on the rvm homepage)
