rake (0.9.2, 0.8.7)

当 gem list 清楚地显示 gem 存在时，我怎么会收到这个错误?

How can I debug and resolve this issue?

我的 gemfile 是:

My gemfile is:

gem 'rails', '3.0.4' 
gem 'sqlite3' 
gem 'sqlite3-ruby', :require =>'sqlite3'

推荐答案

你需要在你的 Gemfile 中 require rake gem

You need to require rake gem in your Gemfile

gem 'rails', '3.0.4' 
gem 'sqlite3' 
gem 'sqlite3-ruby', :require =>'sqlite3'
gem 'rake', '0.9.2'

现在运行 bundle install 确保您已连接到互联网.现在如果你想执行 rake 任务然后使用 bundle exec rake task_name

now run bundle install make sure you are connected with internet. now if you want to execute rake tasks then use bundle exec rake task_name
