在Ruby on Rails - Heroku deployment 上,我得到了一個錯誤,heroku[route]: at=error code=H10 desc="App crashed" method在除錯了一些日志文本之后,我得到了日志檔案的主要部分:

雖然這是生產環境日志全文的主題,但是在本地開發環境中,啟動Rails服務器時沒有發現問題!在開發環境中一切正常。
此外,該 URL 顯示以下文本:
Application error An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command heroku logs --tail
And the console is showing this: Failed to load resource: the server responded with a status of 503 (Service Unavailable)

解決方案
好的,在修復了從日志檔案中發現的錯誤的幾次部署之后,我知道,在我們的Gemfile 中,我們需要添加一些依賴項所需的gem(大約 3 個 gem)。這些寶石是:
# Gemfile
gem 'net-smtp', require: false
gem 'net-pop', require: false
gem 'net-imap', require: false
將它們添加到我們的 gem 檔案后,運行
bundle install
然后在heroku上部署代碼,這將進行正確的部署。
