我越来越类似于那些错误的 这些 问题,除了我的是上发生的Heroku:
2011-05-30T09:03:29+00:00 heroku[worker.1]: Starting process with command: `rake jobs:work`
2011-05-30T09:03:30+00:00 app[worker.1]: (in /app)
2011-05-30T09:03:30+00:00 heroku[worker.1]: State changed from starting to up
2011-05-30T09:03:33+00:00 app[worker.1]: rake aborted!
2011-05-30T09:03:33+00:00 app[worker.1]: uninitialized constant Rake::DSL
2011-05-30T09:03:33+00:00 app[worker.1]: /app/.bundle/gems/ruby/1.9.1/gems/rake-0.9.0/lib/rake/tasklib.rb:8:in `<class:TaskLib>'
这些问题的答案似乎是要指定,gem 'rake', '0.8.7'因为0.9版本会导致问题.
当我尝试添加gem 'rake', '0.8.7'到我的gemfile并推送到Heroku时,我收到此错误:
Unresolved dependencies detected; Installing...
You have modified your Gemfile in development but did not check
the resulting snapshot (Gemfile.lock) into version control
You have added to the Gemfile:
* rake …我知道这是一个常见的问题,但我刚刚开始使用新的Rails 3.1.0和Ruby 1.9.2 p290开发一个项目
在我第一次迁移时,我已经出现了这个错误,我不知道为什么.
