ruby - 如何从 rake 任务启动 IRB 控制台？

Question

我正在尝试编写一个 rake 任务来设置一个镜像我的项目的环境。

task :environment do 
  require 'rubygems'
  require 'sequel'
  # require 'my_projects_special_files'
end

task :foo => [:environment] do
  require 'irb'
  IRB.start
end

导致 irb 提示“foo”不存在(任务名称)

10:28:01:irb_test >> rake foo --trace(in /Users/mwlang/projects/personal/rake/irb_test)** Invoke foo (first_time)** Invoke environment (first_time)** Execute environment** Execute foorake aborted!No such file or directory - foo/opt/local/lib/ruby/1.8/irb/input-method.rb:68:in `initialize'/opt/local/lib/ruby/1.8/irb/input-method.rb:68:in `open'/opt/local/lib/ruby/1.8/irb/input-method.rb:68:in `initialize'/opt/local/lib/ruby/1.8/irb/context.rb:80:in `new'/opt/local/lib/ruby/1.8/irb/context.rb:80:in `initialize'/opt/local/lib/ruby/1.8/irb.rb:92:in `new'/opt/local/lib/ruby/1.8/irb.rb:92:in `initialize'/opt/local/lib/ruby/1.8/irb.rb:57:in `new'/opt/local/lib/ruby/1.8/irb.rb:57:in `start'/Users/mwlang/projects/personal/rake/irb_test/Rakefile:9

IRB.start 正在查看 ARGV，其中包含来自 rake 命令行的任务名称。先尝试清除 ARGV。

require 'irb'
ARGV.clear
IRB.start
