使用angularfire2 v4时出错

Question

I'm trying to build something with new angularfire2 version, but having trouble after trouble. Now I'm stuck at the following error: Failed to compile.

./~/firebase/app/shared_promise.js
Module not found: Error: Can't resolve 'promise-polyfill' in 'my 
directory.../node_modules/firebase/app'
@ ./~/firebase/app/shared_promise.js 37:35-62
@ ./~/firebase/app/firebase_app.js
@ ./~/firebase/app.js
@ ./~/firebase/database.js
@ ./~/angularfire2/database/firebase_list_factory.js
@ ./~/angularfire2/database.js
@ ./src/app/app.module.ts
@ ./src/main.ts
@ multi webpack-dev-server/client?http://localhost:4200 ./src/main.ts

what is wrong?

I fixed it by going in my package.json file and changing the firebase dependency to ^3.6.6. After doing that, save the file and run npm install again. Hope it helps.
