Warning: is not installed on your system

Error message

Warning: ${pmName} is not installed on your system

What it means

setup-package-manager.js `setGlobal` confirms the requested package manager exists in the known PACKAGE_MANAGERS map, then checks whether its binary is actually available on the system (getAvailablePackageManagers). If not installed, it warns but proceeds — the preference is still saved for a future environment where the tool exists.

Solutions

1. Install the missing package manager (e.g. `npm i -g pnpm`, `corepack enable`, or the official installer for bun)
2. Confirm with `pnpm --version` (or the relevant binary) that it is now on PATH
3. Re-run the setter so the warning disappears
4. If intentional, ignore the warning — the preference was saved and will apply once the tool is installed

Example fix

// before
$ node scripts/setup-package-manager.js --set-global pnpm
Warning: pnpm is not installed on your system
// after
$ npm i -g pnpm && pnpm --version
$ node scripts/setup-package-manager.js --set-global pnpm
✓ Global preference set to: pnpm

const pm = 'pnpm';
if (!PACKAGE_MANAGERS[pm]) { console.error('unknown PM'); process.exit(1); }
try { execSync(`${pm} --version`, { stdio: 'ignore' }); } catch { console.warn(`${pm} not on PATH`); }

When it happens

Trigger: Running the setter (e.g. `node scripts/setup-package-manager.js --set-global pnpm` or equivalent flag) with a valid pmName whose executable is not found on PATH via getAvailablePackageManagers().

Common situations: Configuring a new machine before installing pnpm/yarn/bun; switching preferred PM on CI where only npm is preinstalled; setting a preference for a PM planned to be installed later.
