Ruby on rails bin/rails生成模型文章标题：string text:text

最近，我开始使用并坚持使用

bin/rails生成模型文章标题：string text:text

，它应该创建带有两列

的
模型
，不幸的是输出如下：

在
生成模型之前
调用了
sudo chmod o-w/usr/local/
。假设它们都不影响上述问题

感谢任何解决方案

编辑：
我找了
数据库\u配置
，但运气不好。。我认为这个基本的
database.yml
文件没有任何共同之处，因为它包含：

# SQLite version 3.x
#   gem install sqlite3
#
#   Ensure the SQLite 3 gem is defined in your Gemfile
#   gem 'sqlite3'
#
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:
  <<: *default1
  database: db/production.sqlite3

#SQLite版本3.x
#gem安装sqlite3
#
#确保在gem文件中定义了SQLite 3 gem
#gem'sqlite3'
#
默认值：&默认值
适配器：sqlite3

如果提供了数据库详细信息，请确保database.yml.Indentation中没有空格。单个额外空间可能会导致配置问题。
