If kerl list installations is displaying Erlang installations that you deleted ages ago, and you’ve got all of your installations in ~/.kerl/erlangs/, you can rebuild the list by running the following command:

kerl allows you to easily build and install multiple Erlang/OTP releases. It’s kinda like nvm or rvm, but for Erlang. It doesn’t do everything, and that’s what direnv is for. direnv allows you to run commands upon entering or leaving a particular directory.
