SSG support detected already. Aborting.

Error message

SSG support detected already. Aborting.

What it means

Warning emitted by `quasar mode add ssg` when SSG support is already installed. addMode detects the existing mode via isModeInstalled(appPaths, 'ssg'), optionally refreshes its dependencies (with forced reinstall when needed), warns, and returns without re-scaffolding. A controlled abort, not a failure.

Solutions

1. No fix needed — proceed with `quasar dev -m ssg` or `quasar build -m ssg`.
2. If src-ssg dependencies are stale, force a dependency refresh so ensureModeDeps reinstalls them.
3. If src-ssg is corrupted or partial, delete it and run `quasar mode add ssg` again.

import { existsSync } from 'node:fs'
import { join } from 'node:path'
if (!existsSync(join(process.cwd(), 'src-ssg'))) {
  await execa('quasar', ['mode', 'add', 'ssg'])
}
await execa('quasar', ['build', '-m', 'ssg'])

When it happens

Trigger: Running `quasar mode add ssg` when the project already contains src-ssg. Also fires when dev/build commands with the SSG mode internally invoke addMode on an already-configured project and silent is not true.

Common situations: Re-running the add command after a previous install; CI scripts or templates that run `quasar mode add ssg` unconditionally; running `quasar dev -m ssg` on an already SSG-enabled project.
