我无法在我的项目中执行rake任务。我总是收到以下错误消息：

rake aborted!

ruby 1.8.7（2011-02-18 patchlevel 334）[i686-darwin10.8.0]

Rails 2.3.11

rake，版本0.8.7

我尝试使用rake 0.9.2和/或ruby 1.9.2但没有取得更多成功。

以下是我的Rakefile的内容：

# Add your own tasks in files placed in lib/tasks ending in .rake,
# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.

require(File.join(File.dirname(__FILE__), 'config', 'boot'))

require 'rake'
require 'rake/testtask'
require 'rdoc/task'

require 'tasks/rails'

感谢您的帮助！

Answer 1

如果这是一个自定义Rake任务......在Rails中定义了to_sentence数组扩展，那么您需要确保加载Rails。

确保您在rake任务中加载环境：

task :my_task => :environment do
...

如果这不是自定义Rake任务，那么您的环境似乎有问题。尝试升级RVM。

Answer 2

如果您安装了bundler，请尝试

bundle exec rake --tasks

不确定它是否有用但值得一试。
