你尝试过搜索吗？ http://stackoverflow.com/questions/6862032/another-uninitialized-constant-rakedsl –

可能重复[耙中止！未初始化的常量Rake :: DSL上的heroku]（http://stackoverflow.com/questions/6727898/rake-aborted-uninitialized-constant-rakedsl-on-heroku） – s84

Rake aborted! Uninitialized constant Rake::DSL on Heroku

I have a blog post about this here有两种方法可以做到这一点：

只能使用老版本的耙子：

查看当前的耙子版本$ gem list。看看你有哪些版本的耙子，除了0.8.7之外全部移除。您可以使用gem uninstall rake -v=0.9.1或任何需要删除的版本删除宝石。

或者只是一个衬垫添加到您的耙文件：

除非你有使用旧版本的斜掠更容易此行require 'rake/dsl_definition'添加到您的Rails的应用Rake文件。

require File.expand_path('../config/application', __FILE__) 
require 'rake/dsl_definition' 
require 'rake'
