To get help with a specific command, type firebase help [command_name]

$ firebase -V

Gives a version number, but I don't know if it's the version number of Firebase Tools.

The only command for tools is:

tools:migrate [options]

Which is to: ensure your firebase.json format is up to date

How do I get the current version of firebase tools?

Solution 1

The flags -V and --version outputs the version number for firebase-tools. So to determine the current version, run:

firebase --version

To upgrade Firebase tools to the latest version, run:

npm upgrade firebase-tools -g

Solution 2

Try running :

 firebase tools --version

Solution 3

Run firebase tools --version to check version.

And as per the prompt, run npm install -g firebase-tools to update.

Update

You're right. It looks like it matches the version numbers of this library, but not another.

Running npm upgrade firebase-tools -g ran an update and displayed -- [email protected] But, I wanted to know my current version before updating. So, if I don't want the most recent version, I now need to revert back somehow, and that's what I wanted to avoid.

I just realized that the command $ firebase -V does give the version number of Firebase Tools. After updating to 6.1.2 I ran $ firebase -V again, and it displayed 6.1.2 and previously it displayed 6.1.1

Ah, I see that you your question. I'll update my answer, but I'm also just happy you got it sorted.

CAUTION: This doesn't answer the question, but instead changes your system. The correct answer is the one by Fakebounce (firebase tools --version). Any other answer (at the time of writing) is more correct than this.

[auspicious99]

But if an upgrade is available, this doesn't tell you, unlike firebase tools --version. Are there some other benefits of using firebase --version besides not having to type the "tools" in the middle?

Since it only outputs the number and nothing else, it's useful for scripting.
