Last verified Sep 9, 2026 against lightningcss-linux-x64-gnu@1.33.0.

lightningcss-linux-x64-gnu declares a CommonJS entry only, but require("lightningcss-linux-x64-gnu") failed on every Node.js version in our probe: Cannot find module 'lightningcss-linux-x64-gnu'. import "lightningcss-linux-x64-gnu" resolves to the same file, so it fails the same way. That usually means a missing peer dependency, a browser-only global, or a package that is not meant to be loaded directly; see the runtime table below.

## What to do

1. require("lightningcss-linux-x64-gnu") failed in our probe on every Node.js version (Cannot find module 'lightningcss-linux-x64-gnu'); check the package README for peer dependencies or setup before relying on it.
2. From ES modules use the default import: import lightningcssLinuxX64Gnu from "lightningcss-linux-x64-gnu"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: no types are available for lightningcss-linux-x64-gnu; declare the module yourself if you need them.
