Unsupported platform

Error message

Unsupported platform: ${platform}

What it means

normalizePlatform maps process.platform values to the release matrix OS names ('win32' -> 'windows') and validates against linux/darwin/windows. Any other platform (freebsd, aix, sunos, etc.) throws because no Nasiko release artifacts are qualified for it.

Solutions

  1. Install Nasiko only on Linux, macOS, or Windows
  2. If in a container/VM, run on a linux/darwin/windows host
  3. Check that you pass raw process.platform values, not re-mapped names

Example fix

// before
normalizePlatform('freebsd', 'amd64');
// after
normalizePlatform('linux', 'amd64'); // or run on supported OS
Defensive patterns

Strategy: type-guard

Validate before calling

const osName = process.platform === 'win32' ? 'windows' : process.platform;
if (!['linux', 'darwin', 'windows'].includes(osName)) {
  console.error(`Nasiko not available on ${osName}; use linux/darwin/windows`);
  process.exit(1);
}

Type guard

function isSupportedOs(platform) {
  const os = platform === 'win32' ? 'windows' : platform;
  return ['linux', 'darwin', 'windows'].includes(os);
}

Try / catch

try {
  const rel = getQualifiedRelease(version);
} catch (e) {
  if (e.message.startsWith('Unsupported platform')) {
    console.error('Install Nasiko on Linux, macOS, or Windows only.');
  } else throw e;
}

Prevention

When it happens

Trigger: Running the Nasiko installer on an OS outside linux/darwin/windows — e.g. FreeBSD, AIX, OpenBSD, or passing a custom platform string into normalizePlatform from a script or test.

Common situations: Installing Nasiko on a BSD-based CI runner or an unsupported embedded OS; scripts hard-coding platform strings like 'win64' instead of process.platform values.
