如何解决Heroku上未初始化的常量Rake :: DSL问题？ [英] How to fix the uninitialized constant Rake::DSL problem on Heroku?

问题描述

我收到的错误类似于 这些 问题，除我的发生在 Heroku ：

I am getting errors similar to the ones in these questions, except mine are occuring on 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指定 gem'rake'，'0.8.7' 因为0.9版本会导致问题。

The answer in those questions seems to be to specify gem 'rake', '0.8.7' because the 0.9 version causes the problem.

当我尝试添加 gem'rake'，'0.8.7 '到我的gemfile并推送到Heroku我得到这个错误：

When I try to add gem 'rake', '0.8.7' to my gemfile and push to Heroku I get this error:

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 (= 0.8.7)
FAILED: http://devcenter.heroku.com/articles/bundler
! Heroku push rejected, failed to install gems via Bundler
error: hooks/pre-receive exited with error code 1
To [e-mail]:my_app.git
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to '[e-mail]:my_app.git'

我的gemfile通常在Heroku上正常工作。我应该怎么做？

My gemfile normally works fine on Heroku. What should I do?

推荐答案

把它放在Rakefile 上面 require'rake' p>

Put this in your Rakefile above require 'rake':

require 'rake/dsl_definition'
