Please try uninstalling `watchman` and try running the watch task again.

### The `build` command (or `bin/rails assets:precompile`) is hanging inside a docker container

Without a `WORKDIR`, tailwind may search the entire filesystem for files with CSS class names. So, please make sure your Dockerfile uses a `WORKDIR`.

### Lost keystrokes or hanging when using terminal-based debugging tools (e.g. IRB, Pry, `ruby/debug`...etc.) with the Puma plugin

We've addressed the issue and you can avoid the problem by upgrading `tailwindcss-rails` to [v2.4.1](https://github.com/rails/tailwindcss-rails/releases/tag/v2.4.1) or later versions.
