Q&A
pacage.jsonとfirebase.jsonの内容を追記いただけますか？
#前提・実現したいこと
以下２つのサイトを参考にcloud functions for firebaseの環境構築を行なっていますが、デプロイでエラーが発生しており、私がNode.jsなどに関して初心者なので解決できません。
よろしくお願いいたします。
はじめに: 最初の関数の記述とデプロイ
Firebase で Cloud Functions を簡単にはじめよう
基本的には上のリンク（公式のやつ？）に従って進めました。流れは
1.プロジェクト作成
2.Node Version Managerのインストール（v8.17.0）
3.npm install -g firebase-tools（ターミナルで）
4.firebase login（ターミナルで）
公式だとRealtimeDatabaseの例しか描かれていなかったので、
以降は下のリンクのやり方を参考にしました
5.firebaseプロジェクト用のディレクトリを作成し移動
6.firebase init（ターミナルで）
7./functions/index.jsの内容を書き換え（該当のソースコードに記載）
8.firebase deploy（ターミナルで）
#発生している問題・エラーメッセージ

You can create multiple project aliases by running firebase use --add, but for now we'll just set up a default project. i .firebaserc already has a default project, using ~~~. === Database Setup Firebase Realtime Database Rules allow you to define how your data should be structured and when your data can be read from and written to. ? What file should be used for Database Rules? atabase.rules.json ? File database.rules.json already exists. Do you want to overwrite it with the Database Rules for from the Firebase Console? Yes ✔ Database Rules for have been downloaded to database.rules.json. Future modifications to database.rules.json will update Database Rules when you run firebase deploy. === Firestore Setup Firestore Security Rules allow you to define how and when to allow requests. You can keep these rules in your project directory and publish them with firebase deploy. ? What file should be used for Firestore Rules? firestore.rules ? File firestore.rules already exists. Do you want to overwrite it with the Fire store Rules from the Firebase Console?

If you have a build process for your assets, use your build's output directory. ? What do you want to use as your public directory? public ? Configure as a single-page app (rewrite all urls to /index.html)? No ? File public/404.html already exists. Overwrite? Yes ✔ Wrote public/404.html ? File public/index.html already exists. Overwrite?

Would you like to download the emulators now? No i Writing configuration info to firebase.json... i Writing project information to .firebaserc... ✔ Firebase initialization complete!
お返事が遅くなりました。
以下ファイルの内容を追記します。
しかしながら、
firebase.jsonの"functions"の"predeploy"の
lintの記述を消したらデプロイできるようになりました、、、
lintの記述は消してしまっても問題はないのでしょうか？
宜しくお願い致します
