There was a problem loading the local ${command} command. Ga

Error message

There was a problem loading the local ${command} command. Gatsby may not be installed. Perhaps you need to run "npm install"?

What it means

Thrown from the `catch` block of `resolveLocalCommand`: `require(cmdPath)` threw an error while loading the command module. The command file exists but failed to execute (syntax error, missing transitive dependency, runtime error at module scope). The original error is attached and surfaced via `report.panic`.

Solutions

  1. Read the attached `err` in the panic output to find the underlying cause (syntax error, missing module, etc.).
  2. Reinstall gatsby and its dependencies: `rm -rf node_modules package-lock.json && npm install`.
  3. Ensure your Node.js version satisfies the gatsby major's minimum (see error 191).
  4. If a specific dependency is named in the cause, install/upgrade that package to a compatible version.
Defensive patterns

Strategy: try-catch

Validate before calling

try { require(cmdPath) } catch (e) { console.error('Command failed to load:', e); process.exit(1) }

Try / catch

try {
  const cmd = require(cmdPath)
} catch (e) {
  // surface underlying module error (missing dep, syntax error) instead of generic panic
  reporter.error(`Failed to load ${cmdPath}`, e)
}

Prevention

When it happens

Trigger: Loading `node_modules/gatsby/dist/commands/<command>.js` raises an exception: a `SyntaxError` in the file, a missing dependency it requires, a runtime throw at module-eval time, or an ESM/CJS interop failure. The CLI wraps and re-throws as a panic.

Common situations: Partial/corrupted gatsby install (missing dist files referenced by the command); a dependency of the command module is missing or has an incompatible version; Node version incompatibility with the installed gatsby; transpilation artifacts missing after a interrupted build of gatsby itself.
