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

我試圖用AngularFire2ERROR在./~/firebase/app/shared_promise.js

我下面this guide創建角2應用程序。

每次我嘗試導入AngularFireModule在我的應用程序模塊，然後做AngularFireModule.initializeApp（配置）中，我發現了以下錯誤進口，當我嘗試運行納克服務：

ERROR in ./~/firebase/app/shared_promise.js 
Module not found: Error: Can't resolve 'promise-polyfill' in 
'C:\Users\username\Desktop\demo-app\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.module.ts 
@ ./src/main.ts 
@ multi webpack-dev-server/client?http://localhost:4200 ./src/main.ts 
webpack: Failed to compile.

，這是我的package.json什麼樣子：

您是否在'app.module.ts'中'AngularFireModule'中導入並在NgModule中導入？ –

是的我正在導入app.module.ts – bekamais

我被困在** 4。安裝程序@ NgModule **在AngularFire2安裝指南中，我正在做什麼指南說，但沒有運氣 – bekamais

npm install promise-polyfill --save --save-exact

它適合我。

完美適用於錯誤：無法解析'promise-polyfill'!!!!謝謝 – JamesAnd

npm install promise-polyfill --save-exact

在命令提示符粘貼此命令，並運行它，我有同樣的問題，「https://github.com/stefanpenner/es6-promise」這個帖子幫我解決這個問題。

firebase npm軟件包版本3.7.8中缺少'promise-polyfill'dependencie，您可以安裝'promise-polyfill'或將firebase軟件包降級到3.7.7。

如果您想在package.json中保存依賴項，請確保包含--save標誌以及--save-exact。

npm install promise-polyfill --save --save-exact
