LoadError after running rails c

Question

I am trying to run rails c under my application's folder but I keep getting this error and don't know how to fix it.

Running via Spring preloader in process 15492
Traceback (most recent call last):

I tried to delete tmp folder and run rails s again and update bootsnap gem but I keep getting the same error.

Standard set of questions then: is this a public project? Does it work for anyone else or is this an issue you were given to fix? do you have `rb-readline` gem in your Gemfile? — BroiSatse, Aug 07 '20 at 17:09
Your ruby was built with a version of lib-readline that’s no longer on your system. Have a look at https://stackoverflow.com/questions/4385549/no-such-file-to-load-readline for remedies. Adding ``rb-readline`` gem is often the quickest way to resolve. — rmlockerd, Aug 07 '20 at 17:12
