Firebase not installing in terminal

How can I connect firebase with my app. I’m unable to install firebase. I’m getting this message:

npm WARN eslint-config-exponent@5.1.3 requires a peer of eslint@^3.10.2 but none is installed. You must install peer dependencies yourself.
npm WARN moment@1.0.0 No repository field.

updated 1 package in 3.207s

This doesn’t look like firebase actually failed to install – seems like there are just some optional dependency mismatches. Are you finding that firebase isn’t actually installed?

Do you know how to fix it and make sure that it only uses one dependency. Yes, I’m finding that it is not installed

I would check the node_modules folder and make sure that firebase isn’t there, as it looks like it was installed.

Otherwise you can install the peer dependency and eslint with
npm install --save firebase@4.4.0 eslint-config-exponent@5.1.3 eslint@3.10.2
