# Cannot find module 'tailwindcss' error [Solved]

To solve the error "Cannot find module 'tailwindcss'", install tailwindcss, postcss and autoprefixer as dev dependencies in your project by running npm install -D tailwindcss postcss autoprefixer.

Open your terminal in your project's root directory (where your package.json file is located) and run the following command:

shell

Copied!
npm install -D tailwindcss@latest postcss@latest autoprefixer@latest

install tailwindcss

This will add the tailwind package to the development dependencies of your project.

The postcss package is the easiest way to integrate tailwind with build tools like Webpack, Rollup, Vite and Parcel.

# Delete your node_modules and reinstall your dependencies

If the error persists, try to delete your node_modules and package-lock.json (not package.json) files, re-run npm install and restart your IDE.

If you are on macOS or Linux, issue the following commands in bash or zsh.

shell

Copied!
#  for macOS and Linux
rm -rf node_modules
rm -f package-lock.json
rm -f yarn.lock

# 👇️ clean npm cache
npm cache clean --force

# 👇️ install packages
npm install

If you are on Windows, issue the following commands in CMD.

cmd

Copied!
# for Windows
rd /s /q "node_modules"
del package-lock.json
del -f yarn.lock

# 👇️ clean npm cache
npm cache clean --force

# 👇️ install packages
npm install

Make sure to restart your IDE and dev server if the error persists. VSCode often glitches and needs a reboot.

# Make sure the packages are in your devDependencies object

If the error persists, open your package.json file and make sure it contains the tailwindcss package in the devDependencies object.

package.json

Copied!
{
  "devDependencies": {
    "autoprefixer": "^10.4.4",
    "postcss": "^8.4.12",
    "tailwindcss": "^3.0.23",
  },
}

If your error is not resolved, visit the official tailwindcss installation guide and in the Framework Guides tab, click on your framework or build tool, e.g. Create React App, Vite or Angular and follow the step-by-step guide.
