“An unexpected error has occurred” after firebase deploy

Question

When I am hosting my web page through firebase hosting then after writing command firebase deploy I got the following error:

Microsoft Windows [Versi         


        

Answer 1

For me updating firebase-tools solved the issue

run below command in your cmd prompt

npm install -g firebase-tools

then try firebase init again

Answer 2

I get that error when I haven't run npm install. Try it out. I hope that simple solution helps anyone with the same problem.
