WARNING in ./node_modules/Firebase/dist/index.cjs.js
angular で Firebase を使ったときに起こったWARNING
解決しないと実行できません。。
[ng] WARNING in ./node_modules/Firebase/dist/index.cjs.js [ng] There are multiple modules with names that only differ in casing. [ng] This can lead to unexpected behavior when compiling on a filesystem with other case-semantic. [ng] Use equal casing.

ワーニングの内容は
複数のモジュールで名前がケースによって異なる
大文字、小文字のファイルをコンパイルすると、予期しない動作につながる可能性がある
といった感じ。
detail.page.ts のfirebaseのimport記述を確認したところ
import * as firebase from 'Firebase';
となっていた。
警告通り、大文字Fを小文字fに変更してみた
import * as firebase from 'Firebase';
そして実行。

modulesの数字が変化した。
解決したのか？
同様に create.page.ts のimportも修正し実行。

無事解決 ヽ(^o^)丿
githubに載っていたものを参考にしたんだけど。。。
Firebaseの「F」の大文字が原因だったのか？
