FirebaseCommandException: An error occured on the Firebase CLI when attempting to run a command

I passed through the same issue on Windows. I figured out that installing Firebase CLI using the binary file didn't work for me (even after @Ventosus answer), so here is my answer.

I had to install the Firebase CLI using the npm command (node.js is required to use this command) :

npm install -g firebase-tools

I've then been able to run the command : flutterfire configure

Here is the documentation you have to follow in case you don't have node.js or if you need any information : Firebase CLI documentation

For solving the standalone issue part of your question:

1 copy the downloaded .exe to your flutter project folder

2 rename it from firebase-tools-instant-win to just firebase (exe)

3 run "firebase login" from cmd line in the folder where you put the .exe and continue with flutterfire configure

This is a quick setup for a single project, if you plan to use firebase cli across multiple projects, you need to rename and move the .exe to a suitable location and fix env/paths issues.

Run:

firebase logout 

Then:

firebase login 

The issue is that your token expired.

for macOS user:

Enter dart pub global activate flutterfire_cli on your terminal.

It will successfully install the fluterfire_cli but with the warning:

The solution is to update the environment path.

Open terminal.

1. vim .zshrc

2. Press "i" key to activate insert mode.

3. add export PATH="$PATH":"$HOME/.pub-cache/bin"

4. Press "Esc" then write :wq in terminal and press enter to exit vim.

5. Reopen the terminal and check "flutterfire --version"

6. firebase login

7. flutterfire configure

For Windows Users, Make 2 CLI Installations

https://firebase.google.com/docs/cli#install-cli-windows

1. Windows Installation - it has gui, which is good
2. npm installation - for the flutterfire to be recognized - npm install -g firebase-tools

Do not use bash, use the cmd to execute flutterfire commands.

For me it was that my authentication token was expired. As @DeePanShu pointed out, you should do

firebase logout && firebase login

But, if that's not the case, I highly recommend to read the file generated when the error happens (it will be saved in your app folder). There's a description of the problem, so you can avoid trying out solutions without knowing the actual problem.

Download the standalone binary for the CLI for windows

It will download an executable firebase-tools-instant-win.exe

Copy into your preferred location

The important part is to enter the path where the executable resides in the Environment variables

Environment variables -> System variables -> Path -> new -> Enter the path

Launch the file and enter the necessary commands.

firebase login

dart pub global activate flutterfire_cli

[your project directory]$  flutterfire configure

In case you run into another problem especially this

Unhandled exception:
FormatException: Unexpected character (at character 1)...

after @Ventosus' answer, check this github issue out, it helped me solve this issue.

I had the same issue and tried everything I could. but npm method worked really well. Install nodejs from https://nodejs.org/en/

this will also install npm to your system. then just run the command npm install -g firebase-tools

and you are good to use all firebase functions

All information I told I gained it from documentation. Developers best friend

The only thing helped me on Windows is just to use Android Studio's built-in terminal. Powershell and firebase exe both throw different errors and won't work. I also used all the solutions mentioned here and there with no luck.

Hello guys I tried to use the binary file from the official CLI website which is firebase-tool-instant-win.exe and naming it firebase.exe , then putting it in the flutter project file that I am working on , seems to do the trick

if you have installed firebase CLI with npm and still getting the error. Try to restart your system and then try running the commands

Make sure that you are using same gmail account, signed in firebase cli and firebase console.

Then Relogin into the firebase cli

1.firebase logout

2.firebase login

For me, it works only in command prompt(not PowerShell or node js runtime): ms windows
