i am also having this problem. did you find a solution?

Seems to be related to the new portfinder release.
http-party/node-portfinder#84

The code used by the emulator fails with the latest version (1.0.22):

await pf.getPortPromise({ port, stopPort: port });

A workaround could be (besides using the old 1.0.21 version) :

await pf.getPortPromise({ port, stopPort: port + 1 });

QuickFix
Edit the file firebase-tools/lib/emulator/controller.js in node_modules and change yield pf.getPortPromise({ port, stopPort: port }) to yield pf.getPortPromise({ port, stopPort: port + 1 })

There is an open pull request which fixes this "bug": http-party/node-portfinder#86

I can confirm the QuickFix is working for me.

This works fine! Thank you!

where is? node_modules/firebase-tools/lib/emulator/controller.js
I cannot find "firebase-tools" folder in node_modules. I able to find only firebase-funstions and firebase-admin.

It's in your global node_modules dir, not in the project one.

@meltedmoon the mentioned node_modules is not the node_modules in your project folder, but rather the node_modules for the packages you install globally. I can give you an example possible location in MacOS and you'll need to figure out the similar location in case you're in Windows.

/⁨usr⁩/⁨local⁩/⁨lib⁩/⁨node_modules⁩/⁨firebase-tools⁩/⁨lib⁩/⁨emulator⁩/controller.js

Thanks for your kind help, I able to find it.
Windows location for firebase-tools is:
*C:\Users[user]\AppData\Roaming\npm\node_modules\firebase-tools*

micksatana · 2019-08-19T03:37:40Z

In case someone want to find global node_modules to apply the quick fix. you can run npm root -g to see where your global node_modules are.

lookfirst · 2019-08-19T10:01:37Z

One line fix on OSX:

sed -i '' 's/stopPort: port/stopPort: port+1/' node_modules/firebase-tools/lib/emulator/controller.js

Hacksore · 2019-08-19T13:21:05Z

Combining both @micksatana and @lookfirst ideas together into the true one liner.

sed -i '' 's/stopPort: port/stopPort: port+1/' $(npm root -g)/firebase-tools/lib/emulator/controller.js

YMMV.

lookfirst · 2019-08-19T14:16:26Z

@Hacksore Only if you've installed firebase-tools globally, which is something I personally try to avoid with npm packages. I'd rather go with any alias in my .bashrc file:

export PATH="${PATH}:./node_modules/.bin"

Or just always use npm run firebase which adds node_modules/.bin to your path.

The reason I avoid this is because this allows me to have different versions of dependencies in each project. If I decide I never want to use firebase again, I just remove the projects and I don't have to remember to remove anything globally. I also don't have version conflicts and strange behaviour this way.

Yes, the cost is more disk space, but disk is cheap.

yuchenshi · 2019-08-19T20:33:38Z

Thanks everyone for the discussion. As we've noticed, this is caused by a breaking change in portfinder and now fixed by https://www.npmjs.com/package/portfinder/v/1.0.23 . If you're interested in how and why this broke us, see http-party/node-portfinder#89

A clean install / update like npm install -g firebase-tools@latest should fix the issue.

* Pin portfinder@1.0.21. Fix #1606. * portfinder 1.0.23 should come with the fix. * Update package-lock.json.

yuchenshi · 2019-08-20T00:52:27Z

We've also updated the dependency in v7.2.4 so if you install npm install -g "firebase-tools@>=7.2.4" then it's guaranteed to be fixed, bypassing npm local cache, etc.

lookfirst · 2019-08-20T03:28:20Z

If you're interested in how and why this broke us, see http-party/node-portfinder#89

@yuchenshi

I wasted a couple hours trying to figure out what the problem was.

How about pinning ALL (instead of the current 'some') of the versions in package.json so that future versions don't screw things up?

Additionally, you should consider handling the error more gracefully (ie: a better error message and stack trace).

I found that updating the global firebase-tools package to the latest version (7.2.4) fixed the issue for me

eriktrom · 2019-08-20T20:25:04Z

bug is fixed via a revert to portfinder (yesterday) - yarn upgrade portfinder -L or npm equiv, fyi

@Jank1310 I just did your suggestion and get :

i  Starting emulators: ["functions"]
✔  functions: Using node@8 from host.
Error: An unexpected error has occurred.

have any idea?

@akildemir
There is no need to apply the quick fix. You can just upgrade the global module.

npm i -g firebase-tools

I just had this issue pop up after Mac OS upgrade
MacOS: 10.15.2
firebase-tools: 7.12.1

Any ideas?

yuchenshi · 2020-01-22T19:16:34Z

@TomKaltz Would you mind opening a new issue? That helps us a lot when triaging.

I found and killed the process with the help of this https://stackoverflow.com/questions/3855127/find-and-kill-process-locking-port-3000-on-mac

lsof -i tcp:5001

Then I killed the PID with kill -9 PID

Rehan-05 · 2022-08-30T08:08:59Z

If you are facing this issue in macOS Pro then this solution is for you.

In MacOS , Port 5000 may be claimed by a new "AirPlay Receiver". This can be disabled in Settings -> Sharing:

I'm also adding the Screenshot of settings panel for disabling AirPlay Receiver.

Disabling the AirPlay Receiver (if you do not need it) frees up port 5000.
