Disclaimer

Cuz I mainly develop using python, so I am not sure the would this workaround give you a correct ruby env or just change the path and get rid of the warning

Background

In my case, I installed rvm first, and then pyenv later. The config for both of them will change $PATH. From the warning, it seems that rvm always want to be the first in the path

$ echo $PATH

$HOME/.rvm/gems/ruby-2.6.3/bin: ......

But if you add eval "$(pyenv init -)" as required by pyenv, it will change your $PATH to

$ echo $PATH

$HOME/.pyenv/shims:$HOME/.rvm/gems/ruby-2.6.3/bin: ......

My workaround

$ rvm use system # Switch back to system ruby

$ rvm use ruby-2.6.3 # Switch to the version you need to use

rvm will change the path to what it likes then you won't see the annoying warning again.
