Solve - Cannot find module 'prettier' error #

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
npm install --save-dev prettier
This will add the prettier package to the development dependencies of your project.

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 restart your IDE.

shell
# 👇️ delete node_modules and package-lock.json rm -rf node_modules rm -f package-lock.json # 👇️ clean npm cache npm cache clean --force npm install
Make sure to restart your IDE and dev server if the error still persists. VSCode often glitches and a reboot solves things sometimes.

If you're still getting the "Cannot find module 'prettier'" error, open your package.json file and make sure it contains the prettier package in the devDependencies object.

package.json
{ // ... rest "devDependencies": { "prettier": "^2.6.1", } }

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

shell
npm install

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

shell
npm install --save-dev prettier@latest
