Question

我有这样的问题，当我尝试创建数据库时，虽然有错误但是有轨我尝试重新安装mysql，但坚持使用brew

我有这样的版本 mysql - 5.5.25a qt - 4.8.2

Answer 1

我不确定qt brew包与ruby，rails和数据库有什么关系？

但是来自ActiveRecord 3.2.11：

ActiveRecord::Base.configurations.values_at(*environments).compact.reject { |config| config['database'].blank? }

看起来这是尝试从配置加载数据库，可能来自config / database.yml。

您是否留下了文本“brew install qt #MySQL。建议使用版本4.1和5.0。”在yaml里面使它无效？

否则，Ruby YAML解析器可能会以某种方式被破坏。
