No ${mode.toUpperCase()} support detected. Aborting.

Error message

No ${mode.toUpperCase()} support detected. Aborting.

What it means

`quasar mode remove <MODE>` checks whether the mode's support folder (e.g. /src-pwa, /src-electron) exists before deleting anything. If the mode was never added (or was already removed), the CLI warns and aborts instead of deleting blindly. Exit code 0 — no harm was done.

Solutions

1. Do nothing — the mode is not installed, which is the desired end state.
2. Verify installed modes with `quasar mode` before scripting removal.
3. If the mode should be installed, run `quasar mode add <mode>` first.

Example fix

// before
ci-clean.sh: quasar mode remove pwa || true
// after
ci-clean.sh: quasar mode | grep -q 'Mode PWA.*yes' && quasar mode remove pwa --yes

// bash: only remove when installed
quasar mode | grep -q "Mode ${MODE^^}.*yes" && quasar mode remove "$MODE" --yes

// the warning is not fatal (exit 0); treat absence as success in scripts
if (!output.includes('Aborting')) { /* proceed */ }

When it happens

Trigger: Running `quasar mode remove <mode>` when `isModeInstalled(ctx.appPaths, mode)` returns false, i.e. the mode's src directory is missing from the project (mode.js:145-148).

Common situations: Cleanup scripts that remove all modes unconditionally; running remove twice; typos in a CI script where the mode was never actually added to this project; a fresh clone that lacks the mode folder.
