title: Duplicate Sass Dependencies
url: "https://nextjs.org/docs/messages/duplicate-sass"

## Why This Error Occurred

Your project has a direct dependency on both `sass` and `node-sass`, two
different packages that both compile Sass files!

Next.js will only use one of these, so it is suggested that you remove one or the
other.

## Possible Ways to Fix It

The `sass` package is a modern implementation of Sass in JavaScript that
supports all the new features and does not require any native dependencies.

Since `sass` is now the canonical implementation, we suggest removing the older
`node-sass` package, which should speed up your builds and project install time.

**Via npm**

```bash filename="Terminal"
npm uninstall node-sass
```

**Via Yarn**

```bash filename="Terminal"
yarn remove node-sass
```
