Question

我已将rails2升级到rails3，当我尝试rake db：migrate时，我发现以下错误

**调用db：migrate（first_time）

**调用环境（first_time）

**执行环境

DEPRECATION警告：不再自动包含ActiveSupport :: Concern中的InstanceMethods模块。请直接在ActiveSupport :: Callbacks中定义实例方法。（来自/home/cis/.rvm/gems/ruby-1.9.3-p392@rails3214/gems/actionpack-3.2.14/lib/action_dispatch/middleware/reloader.rb:29）

**调用db：load_config（first_time）

**执行db：load_config

**执行db：migrate

rake aborted！

Answer 1

错误是由于某些db / migration文件中的非ascii字符引起的。添加

#encoding: utf-8

到你看到奇怪字符的文件

Answer 2

这似乎是编码错误

将以下行添加到environment.rb文件并运行迁移

Encoding.default_external = Encoding::UTF_8
Encoding.default_internal = Encoding::UTF_8

Rake db：从rails2升级到rails3时迁移错误
