I'm working on a React project using shadcn/ui and tried to set up Tailwind CSS by following these steps:
BASHnpm install -D tailwindcss postcss autoprefixer
BASHnpx tailwindcss init -p
However, when I ran the second command, I received the following error:
npm error could not determine executable to run npm error A complete

I’ve seen other reports with similar issues but haven’t found a solution that works for my setup.
How can I fix this issue and successfully initialize Tailwind CSS using npx in my project?

Below is a list of steps that have helped others resolve a similar error (“could not determine executable to run”) when initializing Tailwind CSS. You can try these one by one in your project:
Sometimes npx may pick an outdated or locally cached version. Try forcing the latest version by running:
BASHnpx tailwindcss@latest init -p
A corrupted cache can sometimes lead to issues with finding executables. Clear the npm cache with:
BASHnpm cache clean --force
Then try running the initialization command again.
Make sure that Tailwind CSS is correctly installed as a dev dependency in your project. In your project folder, check that the following command ran without errors:
BASHnpm install -D tailwindcss postcss autoprefixer
After reinstalling (or if you’re unsure), you can remove your node_modules folder and package-lock.json file and run:
BASHnpm install
Then retry the Tailwind CLI command.
If the above steps do not work, you might install the Tailwind CSS CLI globally as a temporary workaround:
BASHnpm install -g tailwindcss
Then run:
BASHtailwindcss init -p
While a global install isn’t always recommended for project consistency, it may help confirm that the issue is with the local executable lookup.
The error shows you’re running npm version 11.0.0, which is relatively new. There are reports that some npm versions may misbehave with the “npx” or “npm exec” command. If nothing else works, try downgrading to a more mature version (for example, npm 9.x):
BASHnpm install -g npm@9
Then verify the version with:
BASHnpm -v
And re-run your Tailwind CLI command.
Give these steps a try. In our experience, explicitly specifying the package version (option 1) or clearing the cache (option 2) tends to resolve the “could not determine executable to run” issue in many cases.

We've discussed shadcn/ui in more detail, which, as of today, does not officially support v4. That is, the steps required for v4 installation are not present in its documentation.
The Shadcn UI installation with Vite guides are still based on TailwindCSS v3. You can either use them with
npm install tailwindcss@3or completely disregard them and follow the steps for TailwindCSS v4 instead:
- Installing TailwindCSS with Vite - v4 Docs (use instead of step#02 for TailwindCSS v4)
shadcn-ui/ui#6446 - GitHubshadcn-ui/ui#6585: Tailwind v4 and React 19 - GitHub
Recently, we updated the v3 documentation with the TailwindCSS team. The new v3 installation is:
BASHnpm install tailwindcss@3
However, this was not reflected in the shadcn/ui documentation.
If you install TailwindCSS with this command, you'll be installing v3, and you can follow the old installation procedure. In other cases, you will be installing v4, which can be installed using the guide linked above and can be understood.
