I am having the hardest of times just trying to get through the cloud functions tutorial here. Every time I try to do firebase deploy --only functions, I always get an error. My firebase-debug.log looks like this

I would appreciate any help in this area! I have already tried deleting the functions directory and just running firebase deploy but that has been unsuccessful. I have also tried downgrading node.js and npm to 6.9.2 (using n) but that hasn't worked either. Any help would be greatly appreciated!

You should bump your cli version from 6.3.0 to 7.1.0 or above, as it fixes the issue reported here https://github.com/firebase/firebase-tools/issues/1469

Maybe also double check that your cloud functions package is up to date? It's hard to tell from your question what your current version is.

  • Ok, so I did ```npm install -g firebase-tools@7.1.0```, but I still got the same error that is above with the .log file. How do I check the cloud functions package to see if it's up to date? My firebase version with ```firebase --version``` is 6.3.0 – jeff-ridgeway May 06 '20 at 21:38
  • Hmm, sounds like it didn't update if the --version is still 6.3.0. Can you try running `npm install -g firebase-tools@latest`. The version should be 8.2.0 (the latest as of today) when you type in `firebase --version`. – dmchk May 06 '20 at 22:30
  • Yeah something is going on with my local computer? I run ```npm install -g firebase-tools@latest``` but when when I run ```firebase --version``` I still get 6.30 afterwards. I don't know why. I do get a warning saying ```deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142``` but I don't know what this means. – jeff-ridgeway May 07 '20 at 01:12
  • My guess is you may have additionally installed it not using npm, so it's pulling from a different place in your $PATH. You can run `which firebase` to find out. If you're not too familiar with what you're doing, I suggest uninstalling the npm package, making sure `firebase` is no longer installed anywhere else (and remove it if it it is), and then reinstalling the npm package. I think this is the root of your problem - good luck! – dmchk May 07 '20 at 02:26
  • I figured it out! I had to follow the steps [here](https://stackoverflow.com/questions/12607155/error-the-brew-link-step-did-not-complete-successfully) and [finally here](https://github.com/firebase/firebase-tools/issues/113) in that order. Thanks for the help! – jeff-ridgeway May 09 '20 at 22:27

So, I went down the rabbit hole online for a few days and finally found a solution through a combination of stackoverflow and GitHub.

First, do the instructions outlined here

Then, lastly do this in your terminal: alias firebase="`npm config get prefix`/bin/firebase" which was from this closed GitHub issue

Hope it helps someone!

  • From my own research, it seems information on cloud functions is patch work. The tutorials in docs in various places rarely work without some hair pulling. Is there a reliable source that actually explains cloud functions, showing how they work in detail? – user3951320 Jun 15 '20 at 11:30
