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

** Invoke db:migrate (first_time)

** Invoke environment (first_time)

** Execute environment

该错误是由于某些 db/migration 文件中的非 ascii 字符造成的。添加

#encoding: utf-8

到你看到奇怪字符的文件

好像是编码错误

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
