Problem

What version of Tailwind CSS are you using? v4.0.16 What build tool (or framework if it abstracts the build tool) are you using? tailwind-cli What version of Node.js are you using? 21.7.3 What browser are you using? N/A What operating system are you using? macOS Describe your issue Just noticed this on a deploy to Heroku, our normal build step for Tailwind is hanging. No issues locally until I force it to install 4.0.16 and then it just hangs. No errors. I don't see a debug or verbose output option for the cli so I'm not sure what to do to further troubleshoot. Adding `"@tailwindcss/cli": "4.0.15"` to package.json, to force a downgrade to 15, and all is well again. [code block]

Solution: cli hangs on version 4.0.16

Low Risk

I've had the same issue on a ruby project, using 4.0.16. Downgrading to 4.0.15 solved the issue. I'll see if I can catch the view (`html.erb, html.slim` or `html.haml`) file that would be causing this issue and get a docker image for you to work on.
