Error: Cannot find module 'tailwindcss/nesting' when providing postcss config

[rachelgraves]

Greetings! I am trying to use postcss with tailwindcss-rails so that I can take advantage of nesting. When I follow the instructions in the readme and add the following in config/postcss.config.js I get the error:

Error: Cannot find module 'tailwindcss/nesting'
Require stack:
| - config/postcss.config.js
| - /snapshot/tailwindcss/node_modules/lilconfig/dist/index.js
| - /snapshot/tailwindcss/lib/cli/build/plugin.js

| - /snapshot/tailwindcss/lib/cli/index.js
| - /snapshot/tailwindcss/lib/cli.js
| - /snapshot/tailwindcss/standalone-cli/standalone.js

Rails 7.2 using Propshaft, ruby 3.3.5

@rachelgraves Sorry you're having a problem. Can you share the contents of your postcss.config.js file, and also share what command you're running and the full output?

@ahmeij tagging you in case you have any ideas here (since you wrote the postcss docs).

Hi, can you provide the used version of tailwindcss-ruby (used by tailwindcss-rails) and tailwindcss-rails itself? (next to the contents for the postcss config file).

Thanks
