Though this was the main topic of the full log text on production environment, but in local development environment, there was no issues found while starting the Rails server.虽然这是生产环境日志全文的主题，但是在本地开发环境中，启动 Rails 服务器时没有发现问题。 Everything was working fine on development environment.在开发环境中一切正常。
Besides, the URL was showing the following texts:此外，URL 显示以下文本：
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)

Solution解决方案
Ok, after a few deployments of fixing the errors found from the log file, I got that, in our Gemfile , we need to add some gem (around 3 gems) which are needed for some dependencies.好的，在修复了从日志文件中发现的错误的几次部署之后，我知道，在我们的Gemfile中，我们需要添加一些依赖项所需的gem （大约 3 个 gem）。 Those gems are:这些宝石是：
# Gemfile
gem 'net-smtp', require: false
gem 'net-pop', require: false
gem 'net-imap', require: false
after adding those to our gem file, run将它们添加到我们的 gem 文件后，运行
bundle install
Then deploy the code on heroku and this will make a proper deployment.然后在 heroku 上部署代码，这将进行正确的部署。
