How to fix Rails's warning messages with Ruby 2.7.0

Question

Did anyone resolve this issue with Ruby 2.7.0?

I used rbenv and installed Ruby v2.7.0 and then created a Rails project using Rails v6.0.2

Answer 1

As it's just a warning and won't affect anything, you can just suppress them. I found solution 2 to be the right fit for me.

Option 1. Start the rails server with RUBYOPT='-W:no-deprecated' rails s

Option 2. Set export RUBYOPT='-W:no-deprecated in your bash/zsh profile

Option 3. Set Warning[:deprecated] = false in your ruby code
