There's no local emulators suite on firebase-cli

[francisrod01]

[REQUIRED] Environment info

firebase-tools: 8.2.0

Platform: Linux debian 4.9.0-12-amd64

[REQUIRED] Steps to reproduce

~$ firebase init emulators -y

Then write down the UI lines in the firebase.json, connected on 4000 port.
A related issue here: #2332

"ui": {
      "enabled": true,      // Default is `true`
      "host": "localhost",
      "port": 4000          // If unspecified, see CLI log for selected port
    },

Firebase official doc: https://firebase.google.com/docs/emulator-suite/install_and_configure#configure_emulator_suite

After that, start the emulators.

~$ firebase emulators:start

[REQUIRED] Expected behaviour

Is expected to show the Emulators Suite in UI mode.

[REQUIRED] Actual behavior

There's no Emulators Suite UI on the console, but only hub:

This issue does not seem to follow the issue template. Make sure you provide all the required information.

[francisrod01]

Googling a while I found a solution not described in the docs. #2272 (comment)

It works if I update firebase-tools above 8.4.*.

Update the docs

Could someone update the emulator's section in the docs?

[samtstern]

@francisrod01 yep the emulator suite was released in 8.4!
