Link to the code that reproduces this issue

https://github.com/evgeniyworkbel/my-nextjs16-reprod-app

To Reproduce

  1. Run pnpm create next-app@latest my-app from official nextjs docs
  2. Open package.json file
  3. See "@tailwindcss/postcss": "^4" and "tailwindcss": "^4" into devDependencies section

Current vs. Expected behavior

TailwindCSS docs since v4 shows that its packages is installed in dependencies section (they do not use -D flag in commands)

I expect that create-next-app will install tailiwind according to tw docs too

extent analysis

TL;DR

The issue can be resolved by installing Tailwind CSS packages in the dependencies section instead of devDependencies.

Guidance

  • Review the package.json file to confirm that "@tailwindcss/postcss" and "tailwindcss" are installed as devDependencies.
  • Check the Tailwind CSS documentation for Next.js to ensure that the installation commands match the expected behavior.
  • Consider manually installing the Tailwind CSS packages in the dependencies section using the command pnpm install tailwindcss@latest @tailwindcss/postcss@latest --save.
  • Verify that the packages are installed correctly by checking the package.json file and running pnpm install to ensure that the dependencies are up-to-date.

Example

No code snippet is provided as the issue is related to package installation and configuration.

Notes

The issue seems to be specific to the create-next-app command and the installation of Tailwind CSS packages. The provided environment information and package versions may be relevant to the issue, but further investigation is needed to determine the root cause.

Recommendation

Apply workaround: manually install the Tailwind CSS packages in the dependencies section using the command pnpm install tailwindcss@latest @tailwindcss/postcss@latest --save, as the create-next-app command may not be installing the packages correctly.
