我整天都在玩太空，但在我的生命中，我不能让我的Heroku应用程序迁移数据库。我一直在
rake aborted!
YAML syntax error occurred while parsing /app/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 62 column 3
除了我通过三个不同的验证器运行我的YAML文件并且所有人都告诉他们它们是有效的＆＃39;之外，哪个都很好并且花花公子作为错误。
此处有已编辑的 YAML

解析器错误是由于不一致的缩进造成的。我建议你使用一个体面的文本编辑器并使用2个空格来缩进块。
我不知道你用什么来验证没有捕获错误的YAML - 将粘贴复制到基于Web的验证器并不能很好地工作。相反，您可以使用Ruby YAML模块来解析文件：
# run `$ irb` from the root of project
require 'yaml'
YAML.parse(File.open('./config/development.rb'))
此外，Heroku会将生产设置写入文件中，因此您的production:文件中不应包含database.yml部分。
这是一个正确解析的更正版本：
