Firebase Emulator fails at startup Cannot find module --dns-result-order=ipv4first

Question

The firebase emulator 11.0.0 is failing to start

firebase emulators:start

an Exception is thrown when it gets to Emulator UI...

i ui: Emulator UI logging to ui-debug.log
⚠ ui: Fatal error occurred: Emulator UI has exited with code: 1, stopping all running emulators
i ui: Stopping Emulator UI
⚠ ui: Error stopping Emulator UI

The stack trace from ui-debug.log shows...

node:internal/modules/cjs/loader:936 throw err;

Error: Cannot find module '/Users/hayden/Desktop/parent_app_firebase_cloud_emulator/functions/--dns-result-order=ipv4first'.
at Function.Module._resolveFilename (node:internal/modules/cjs/loader:933:15).
at Function._resolveFilename (pkg/prelude/bootstrap.js:1955:46). at Function.Module._load (node:internal/modules/cjs/loader:778:27).
at Function.runMain (pkg/prelude/bootstrap.js:1983:12).
at node:internal/main/run_main_module:17:47 { code: 'MODULE_NOT_FOUND', requireStack: [] }.

Looks like the error has something to do with line 84...

Starting Emulator UI with command {"binary":"node","args":["--dns-result-order=ipv4first"

Which then throw an error in node as its unable to find a module called --dns-result-order=ipv4first

Any ideas on how to startup the local firebase emulator so it runs without failing with this exception?

Fraudulent

only solution I've found is to revert to Firebase 10.9.2 Please comment/vote if anyone else has the same issue and I'll post the bug on their repo – Fraudulent

Exactly the same. Downgrading firebase cli from 11 to 10.9.2 does the trick for me. Using node 16 – Northward

Execute "npm i [email protected]" to install the version where this issue is not reproducible – Misconstruction

Answer 1

This bug still exists but thanks to the github link provided by @Viktor the firebase team have located the issue and provided a temporary work-around...

Issue source: standalone Firebase CLI binary

Solution: remove the standalone binary & re-install with npm...

Step 1. locate firebase standalone binary..

which firebase

prints something like... /usr/local/bin/firebase

Step 2. rename or delete this folder...

sudo mv /usr/local/bin/firebase /usr/local/bin/firebase_broken

Step 3. reinstall using npm

 npm install -g firebase-tools

Step 4. Good to go! re-run from project folder...

firebase emulators:start

Answer 4

for Mac os, removing firebase cli installed through curl command and using brew instead works fine:

#for uninstalling previous cli package
curl -sL firebase.tools | uninstall=true bash

#new installation using brew command
brew install firebase-cli
