crash - Heroku 应用程序崩溃

Question

我试图找出我的应用程序崩溃的原因，我的 slug 大小非常大 54mb 但在我的计算机上文件夹大小大约为 3mb，这是我的日志文件:(当然 rails 服务器运行得很好，但无法计算解决heroku问题)

Answer 1

深入查看您的日志文件

2011-11-12T20:43:37+00:00 app[web.1]: /app/.bundle/gems/ruby/1.9.1/gems/activerecord-3.1.1/lib/active_record/connection_adapters/abstract/connection_specification.rb:71:in rescue in establish_connection': Please install the postgresql
adapter:gem install activerecord-postgresql-adapter` (pg is not part of the bundle. Add it to Gemfile.) (RuntimeError)

是你问题的原因。

Heroku 提供 PostgreSql - 因此您需要将 pg gem 添加到您的 Gemfile - 假设您目前正在使用 sqlite3 进行开发

group :development do
  gem 'sqlite3'
end

group :production do
  gem 'pg'
end

重新捆绑、提交和重新推送到 Heroku，你应该没问题。
