我开发了rails应用程序，在本地工作正常，当我尝试在生产中运行时，我得到以下内容：
我们很抱歉，但出了点问题。
如果您是应用程序所有者，请检查日志以获取更多信息。
这是我用于制作的命令： rails server -e production
我的环境.rb：
# Load the Rails application.
require File.expand_path('../application', __FILE__)
# Initialize the Rails application.
Rails.application.initialize!
ENV['RAILS_ENV'] ||= 'production'
Database.yml文件：
default: &default
adapter: sqlite3
pool: 5
timeout: 5000
development:
<<: *default
database: db/development.sqlite3
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
<<: *default
database: db/test.sqlite3
production:
adapter: postgresql
database: invmanagement
pool: 5
timeout: 5000
