Git在rubyonrails中推Heroku Master錯誤

Question

首先，我得到了很多其他錯誤，但是我想先從錯誤引導開始。好吧，我想將我的項目推送到我的heroku服務器。我在我的應用程序目錄，然後我運行 「混帳推Heroku的主」，這是我所得到的

Answer 1

首先，我覺得Postgres的是這裏的問題。我相信Heroku和Rails內置PG會導致一些問題。嘗試像這樣編輯您的寶石頁面：

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

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

然後，執行「捆綁安裝」。

如果這不起作用嘗試做「捆綁安裝--without生產的」

希望這有助於。
