我有一个非常奇怪的问题。我正在尝试将我的应用部署到vps。为它创建数据库后，当我尝试迁移我的数据库时，我收到此错误：
YAML syntax error occurred while parsing /root/projects/bbla/config/database.yml. Please note that YAML must be consistently indented using spaces. Tabs are not allowed. Error: (<unknown>): found a tab character that violate intendation while scanning a plain scalar at line 15 column 13
/root/projects/bbla/config/environment.rb:5:in `<top (required)>'
Psych::SyntaxError: (<unknown>): found a tab character that violate intendation while scanning a plain scalar at line 15 column 13
/root/projects/bbla/config/environment.rb:5:in `<top (required)>'
Tasks: TOP => db:migrate => environment
(See full trace by running task with --trace)
这是我的database.yml：
development:
adapter: sqlite3
database: db/development.sqlite3
test:
adapter: sqlite3
database: db/test.sqlite3
pool: 5
timeout: 5000
production:
adapter: postgresql
database: bbla
host: localhost
password: secret
我已经花了几个小时试图搞清楚，但仍然没有运气！也许有人可以看到问题。
我已经在在线yml验证器中检查了我的代码，它说没关系。
非常感谢提前！
更新由Arup Rakshit解决！这是一个奇怪的故障（可能是坏的隐形字符）。帮助删除database.yml并再次创建它，没有复制/过去。
