# execa is not a function when running trigger.dev dev

## The problem

Running `trigger.dev dev` fails with: `execa is not a function`. trigger.dev CLI, v2 era.

## The verified fix

Per a maintainer, this means your Node.js is too old: upgrade to Node v18.5.0+ or v20.5.0+ (the CLI now requires Node 18.20 or later and uses execa v8). The error cannot occur on a supported Node version.
