python - ガンコーンがherokuでエラーを引き起こす

Question

初めてアプリをherokuにプッシュしましたが、ページにアクセスすると「アプリケーションエラー」が発生し続けます.herokuに慣れていないため、ヘルプ/開発センターのリンクに参照が見つからないようです.

heroku ログに行くと、次のようになります。

これらすべてが何を意味するのか、私にはよくわかりません。しかし、それはガニコーンと関係があると思いますか？誰かが問題を指摘するのを手伝ってもらえますか?どうすればこれを修正できますか?

注: いいえ ImportError: xxxxx という名前のモジュールはありません --> xxxxx はアプリの名前です。これは、procfile で使用したものでもあります (例: xxxxx:app)。これは問題ですか？

編集：これはFlaskアプリケーションなので、これが私が持っている現在の構造です

   -static
      --css
      --img
      --js
   -templates
      --index.html
      --layout.html
   -.gitignore
   -Procfile
   -requirements.txt
   -app.py

私のプロフィール:

web: gunicorn app:app

Edit2: これは私の app.py ファイルです

from flask import Flask, render_template

app = Flask(__name__)


@app.route('/')
def main():
    return render_template("index.html")


@app.route('/projects')
def projects():
    ...

...

if __name__ == '__main__':
    app.run()

Profile を次のように設定する場合:

web: gunicorn xxxxx:app

Heroku が実行するコマンドを指定しています。Heroku に移行する前に、開発マシンでこのコマンドを実行できることを確認する必要があります。

gunicorn に渡す "xxxxx" 引数は、gunicorn がアプリケーションオブジェクトを取得するためにインポートするパッケージまたはモジュールです。app.pyでアプリケーションを作成する場合、それは「app」である必要があります (.py 拡張子は含めないでください)。エラーが発生するのは、gunicorn が a を発行し、import xxxxxxその名前のパッケージまたはモジュールを定義していないために明らかに失敗するためです。

コロンの反対側には、アプリケーションの名前を入力する必要があります。たとえば、app.pyファイルに次のコードがあるとします。

app = Flask(__name__)

アプリケーション名はappです。このセットアップの場合、Procfile は次のようになります。

web: gunicorn app:app

次に、gunicorn はimport app(左側app) を発行し、そこで名前が付けられたシンボルを探しますapp(右側app)。

これが役立つことを願っています。
