[EgorKazachenko]

Worked for me npm install firebase --force .

@EgorKazachenko 's solution is the one that works for me.

I’m on Windows 10. Node v8.11.3 NPM v5.6.0

Steps to install everything successfully:

1. Remove node_modules and package-lock.json if they exist. You want to start fresh.
2. Run npm install.
3. After install of everything else without an error, run npm install firebase --force.
4. You will still get node-pre-gyp errors and warnings, but at the end you should see

+ firebase@x.x.x
added x packages in xs

1. Success!

Possible reasons for issues may include being behind a company proxy and/or firewall.
