# Cannot find module 'prettier' error [Solved]

To solve the error "Cannot find module 'prettier'", make sure to install the prettier package by opening your terminal in your project's root directory and running the following command: npm install --save-dev prettier.

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 --save-dev prettier

install prettier module

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

# Delete your node_modules and reinstall your dependencies

If the error is not resolved, try to delete your node_modules and package-lock.json (not package.json) files, re-run npm install and then 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 a reboot solves things sometimes.

# Verify that your devDependencies object contains the prettier package

If you still get the error, open your package.json file and make sure it contains the prettier package in the devDependencies object.

package.json

Copied!
{
  // ... rest
  "devDependencies": {
    "prettier": "^2.6.1",
  }
}

You can try to manually add the line and re-run npm install.

shell

Copied!
npm install

issue npm install

Or try installing the latest version of the package by running the following command:
