我正在尝试按照本文档在 Appfog 上运行 rails 控制台。我按照描述设置了我的 database.yml，但是当我运行时出现RAILS_ENV=proxied-appfog rails console此错误：

/.rvm/rubies/ruby-1.8.7-p352/lib/ruby/1.8/yaml.rb:133:in `load': syntax error on line 22, col 9: `    adapter: mysql2' (ArgumentError)

首先，我不想在 rvm 中触摸任何东西……但我确实打开了该文件以查看问题所在，因为它给了我一个行号。该行不包含任何代码。所以我很困惑。这里有什么问题？我唯一能想象的是，也许它不支持我的 ruby​​ 版本？但如果你输入af runtimes返回的列表是：

+---------+-------------+---------+
| Name    | Description | Version |
+---------+-------------+---------+
| python2 |             | 2.7.3   |
| node08  |             | 0.8.14  |
| php     |             | 5.3.10  |
| java    |             | 1.7.0   |
| ruby18  |             | 1.8.7   |
| ruby192 |             | 1.9.2   |
| ruby193 |             | 1.9.3   |
| node04  |             | 0.4.12  |
| node06  |             | 0.6.17  |
+---------+-------------+---------+

有任何想法吗？

此外，如果我尝试af update使用新的 database.yml 和 proxied-appfog.rb 环境文件，我将无法再启动服务器。因此，在我将更改推送到服务器之前，这个错误就给了我。

您可以逐字发布您的 database.yml 文件吗？你可能有一个语法错误，与空格相关。YAML 对空格敏感。

仔细检查您的 YML 文件是否存在错误空格。使用两个空格而不是制表符缩进子级别。
