Question

我一直试图让我的rails堆栈设置时间最长，到目前为止我已经能够运行一切，但是当我尝试运行rails控制台时出现此错误：

我在网上看到了各种修复，但他们并没有最终解决问题。只是想知道是否有其他人有同样的问题或知道如何解决它。感谢。

Database.yml:
# SQLite version 3.x
# gem install sqlite3
development:
  adapter: mysql
  database: shovell_development
  pool: 5
  timeout: 5000
    username: root
    password: randompassword12
    host: localhost

# 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:
  adapter: mysql
  database: shovell_test
  pool: 5
  timeout: 5000
    username: root
    password: randompassword12
    host: localhost

production:
  adapter: mysql
  database: shovell_production
  pool: 5
  timeout: 5000
    username: root
    password: randompassword12
    host: localhost

Answer 1

问题在于database.yml文件的格式。 timeout: 5000下的行不应该被标记，即：

development:
  adapter: mysql
  database: shovell_development
  pool: 5
  timeout: 5000
  username: root
  password: randompassword12
  host: localhost

Answer 2

username，password和host缩进太多。它们应该与每个环境名称下的其他参数缩进相同。

Answer 3

只需删除用户名，密码和主机左侧的空格，使其对齐并尝试。
