卡皮斯特拉诺中的符号串连接

Question

我在运行卡皮斯特拉诺3号。

我如何才能使下面的行为正确？

我期待着cap deploy:test_symbols会回复“你就是那个男人！”

  task :test_symbols do
    set :what, 'the man!'
    puts "you are #{:what}"

    # below causes error:
    # undefined local variable or method `what' for main:Object

    puts "you are #{what}"

  end

Answer 1

当您set一个变量时，您需要fetch它以供使用：

task :test_symbols do
  set :what, 'the man!'
  puts "you are #{fetch(:what)}"
end
