【问题描述】：

所以我正在尝试将 ruby​​ on rails 应用程序部署到 Amazon AWS Elastic Beanstalk。终端中没有错误，但应用程序不会部署。当我检查日志时，显示了两个错误

Activity execution failed, because: command failed with error code 1: /opt/elasticbeanstalk/hooks/appdeploy/pre/12_db_migration.sh

在这之下……

YAML syntax error occurred while parsing /var/app/ondeck/config/database.yml. Please note that YAML must be consistently indented using spaces. Tabs are not allowed. Error: (<unknown>): did not find expected key while parsing a block mapping at line 21 column 3

Psych::SyntaxError: (<unknown>): did not find expected key while parsing a block mapping at line 21 column 3

Tasks: TOP => db:migrate => db:load_config

我一遍又一遍地检查了我的 database.yml 文件是否有错误，但在这里没有看到任何内容

development:
  adapter: mysql2
  encoding: utf8
  pool: 5
  username: sean
  password: "mypass"
  socket: /var/run/mysqld/mysqld.sock
  database: reviewchipWebsite_development

test:
  adapter: mysql2
  encoding: utf8
  pool: 5
  username: sean
  password: "mypass"
  socket: /var/run/mysqld/mysqld.sock
  database: reviewchipWebsite_test

production:
  adapter: mysql2
  encoding: utf8
  database: ebdb
  username: seanAndrew
  password: "mypass"
  host: aa1bszpu5vavup2.cvln1rz36k57.us-west-2.rds.amazonaws.com

【问题讨论】：

YAML 非常挑剔，你可能会有一些非打印字符（比如额外的换行符）。尝试在yamllint.com 复制粘贴您的 database.yml，它会清理它。

感谢修复

太棒了！如果您不介意，我会将我的评论作为答案:)
