Here’s a clean retype of the steps for anyone who has problems with: <%= stylesheet_link_tag "tailwind", "data-turbo-track": "reload" %>

1. Clean the ambiguous gem warning

gem cleanup stringio

2. Kill the old Rails server process (replace 3231 with your actual pid if different)

kill -9 3231

3. Remove the old server PID file

rm -f tmp/pids/server.pid

4. Start the Rails development environment again

bin/dev
