我正在尝试运行命令
rake db:setup RAILS_ENV="production"
但它给出了以下错误：
DEPRECATION WARNING: Passing a string to ActiveRecord::Base.establish_connection for a configuration lookup is deprecated, please pass a symbol (:mysql) instead. (called from call at /home/huzefa/.rvm/rubies/ruby-2.2.3/lib/ruby/2.2.0/rake/task.rb:240)

我的database.yml文件如下：
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: mysql
encoding: utf8
reconnect: false
database: depot_production
pool: 5
username: huzefa
password: huzefa
host: localhost
这里缺少了什么东西，导致我无法在这里设置生产中的 mysql 数据库？如果有人能帮助我，那就太需要了。谢谢 :)
答案1
database.yml由于文件中存在缩进错误，因此已解决。
