Can't build app after firebase.initializaApp()

[gmot...@gmail.com]

Hello.

I got a problem and I cannot find any answer on internet.

I am building small webapp and use firebase as my backend. Everything was ok and my application run smoothly but today suddenly stop building after 'ng serve'. I always get the same error:

ERROR in ./~/firebase/app/shared_promise.js

Module not found: Error: Can't resolve 'promise-polyfill' in '/Users/user/Desktop/GMO/node_modules/firebase/app'

 @ ./~/firebase/app/shared_promise.js 22:35-62

 @ ./~/firebase/app/firebase_app.js

 @ ./~/firebase/app.js

 @ ./~/firebase/firebase-browser.js

 @ ./src/app/app.component.ts

 @ ./src/app/app.module.ts

 @ ./src/main.ts

 @ multi webpack-dev-server/client?http://localhost:4200 ./src/main.ts

and after deleting and inserting back code lines I found that this error happens after I add: 

firebase.initializaApp({my_database_api_key_and_auth_domain})

inside onInit() function in main component.

Of course when my app was running before I also got this line and everything was ok. I am really out of ideas. I am sure that I didn't change anything in firebase module (inside node_modules) directory.

Can you please help me with that?

Thank you and regards.

What version of firebase are you using? Try to upgrade to 3.7.8. Let us know if this fixes the problem.

Best regards,

This was indeed problem with version.

Solution:

npm install promise-polyfill --save

npm install

Now app is building again.
