(venv) Yoshis-mac:myProject Yoshinori$

試したこと

error code h10の意味は
Heroku Error Codes
Web dynoがクラッシュしていると書いてあります。
同じ内容でerrorを起こしていそうな方の記事をみてみるとProcfileに問題があるのではと思い、内容を変更しましたが、変わりませんでした。
Django: Heroku Failing to launch, at=error code=H10 desc=“App crashed”

guniconeもこちらの記事通りインストールしました。
Deploying Python Applications with Gunicorn

インストールしたあと呼び出せていないということなのでしょうか。
gunicorn.errors.HaltServer: <HaltServer 'Worker failed to boot.' 3>
Procfile
この一文が原因でしょうか。
Haltserverも調べてみたんですがよくわかりません。

Procfile

web: gunicorn myDjango.wsgi --log-file -
web: gunicorn gettingstarted.wsgi
web: python ./main.py $PORT

どうぞ宜しくお願いいたします。

Answer 1

Procfileを修正する場合、次のような手順にするとよいです。

１、Procfile自体をいったん削除して git add .してgit commit -m "procfile delete"などでコミット
２、この状態で一度プッシュ。git push heroku masterなどのコマンド。
３、Procfileを新規作成して、内容を正しいものにして保存。
４、git add .、git commit -m "new procfile"などとしてコミット。
５、git push heroku masterでプッシュ。

お試しくださいませ。

Answer 2

python: can't open file './main.py': [Errno 2] No such file or directoryと出ていますね。
Procfileに書くのはweb: gunicorn myproject.wsgi --log-file -のみでよいはずです。

[yutthi555]

回答ありがとうございます。
web: gunicorn myproject.wsgi --log-file -
のみにしてみたのですが、やはり同じエラーが発生しました。

[Udomomo]

他にコード内などで`main.py`を呼び出している場所はありますか？

[yutthi555]

他の場所で`main.py`は呼び出されていませんでした。
上記に書ききれなかった部分です。
```2018-04-02T05:49:41.360906+00:00 app[web.1]: ModuleNotFoundError: No module named 'hello'```
という箇所がありますが、これは関係していますでしょうか。

[Udomomo]

修正したProcfileをコミットしてからプッシュしましたか？

[yutthi555]

はい。
$git commit -m ""
$ git push heroku master
という手順でpushを行いました。
