rails app to herokuへのデプロイ

Question

私はヒロクにアプリをプッシュしようとしていますが、エラーが続いています。私はherokuがsqlite3をサポートしていないことを知っています。そして、それをバンドルしたgemファイルから削除しました。私のdatabase.ymlファイルはpostgresqlを使用しています。たぶん何か他のsqliteを使用しようとしている？この問題を解決するにはどうすればよいですか？以下は、以下のコマンドの後のherokuからのログです。

である私のdatabase.ymlのファイル

development: 
    adapter: postgresql 
    encoding: utf8 
    database: db/development 
    host: localhost 
    pool: 5 
    timeout: 5000 
    username: sfinley 
    password: password 

test: 
    adapter: postgresql 
    encoding: utf8 
    database: db/test 
    pool: 5 
    timeout: 5000 
    username: sfinley 
    password: password 

production: 
    adapter: postgresql 
    encoding: utf8 
    database: db/production 
    pool: 5 
    timeout: 5000 
    username: sfinley 
    password: password 

です。簡単な検索をすると、すぐに尋ねる代わりに答えが出てきました。とにかく解決策をheres。

はちょうどあなたのGemfile

group :production do 
    gem 'pg' 
    gem 'rails_12factor' 
end 

でこれを行うと、実行bundle install --without production

group :development, :test do 
    gem 'sqlite3' 
end 

にごsqlite3の宝石をシフトし、あなたが行って良いことがあります。 Herokuにプッシュしようとする前に、あなたの新しいコードをgitにプッシュすることを忘れないでください。
