# ignored-compiler-options

#### Why This Error Occurred

Options under the `compiler` key in `next.config.js` only apply to the new Rust based compiler and will be ignored if Babel is used instead. This message will appear if Next.js detects a Babel configuration file while `compiler` options are configured in `next.config.js`
