【问题描述】：

我正在尝试在 Heroku 上迁移我的 postgresql 数据库。当我跑步时

heroku run rake db:migrate

我得到了错误：

Could not find rake-0.9.6 in any of the sources

运行 bundle exec 时出现同样的错误...，

 $rake --version
耙子，版本 10.4.2

我的宝石文件：

    source 'https://rubygems.org'


group :production do
  gem 'pg', '0.15.1'
  gem 'rails_12factor'
end
group :development, :test do 
  gem 'sqlite3'
end

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.1.8'
gem 'rake', '0.9.6'

【解决方案1】：

运行此命令

heroku run bundle exec rake db:migrate

这会起作用。

如果不工作，可能你需要卸载 rake 所以跑吧

gem uninstall rake

然后运行

bundle install

然后

bundle exec rake db:migrate

【解决方案2】：

除非您特别需要该版本，否则我会将 rake 排除在 Gemfile 之外。 Bundler 将使用正确的版本。
