FATAL: Pry failed to get user input using `Readline`.
To fix this you may be able to pass input and output file descriptors to pry directly. e.g.
  Pry.config.input = STDIN
  Pry.config.output = STDOUT
  binding.pry

I tried google it and the only result I found is to add gem "rb-readline", :require => false to GemFile, but it doesn't work for me. Anyone ran into the same issue? Thanks for helping.

Had this issue before, it ended up being a problem with rvm and my path while running rails/bundler commands from a particular prompt.

Try rvm list and rails -v to make sure there are no errors/inconsistencies. Then bundle install and rails console should work fine. Hopefully this helps!

I had the same issue. In my case, The "rails console" was running in another terminal. The issue was resolved as soon as I ended the other execution of the "rails console".

I was able to solve this issue by cleaning my gems and reinstalling using bundler. I was troubleshooting for a long time until I tried that, and then it was fixed in about 2 minutes :)

I used these two commands (make sure you're inside the directory with the issue so bundler has the proper context):

bundle clean --force
bundle install

Had the same issue today. You can just spring stop and relaunch your command.
