File.open("/tmp/test") do |file|
file.each_line("e") {|line|
puts "Got #{ line.dump }"
}
end
返回irb中的“IOError：closed stream”。但是如果被保存在'test.rb'文件中，ruby test.rb - 工作正常。 Ruby版本：ruby-2.0.0-p247，ruby-2.1.0-preview1，Ubuntu，Mac OS。我错了什么？IO错误：在irb中关闭流
user:ads user$ echo "a\nb\nc" > /tmp/test
user:ads user$ irb
2.1.0-preview1 :001 > File.open("/tmp/test") { |file| file.each_line { |line| puts "Got #{ line.dump }" } }
Got "a\\nb\\nc\n"
IOError: closed stream

为我工作,,,！ –
请参阅[这里]（http://www.ruby-doc.org/core-1.9.3/IOError.html），以了解何时会出现这样的错误。但我没有看到任何此类症状你的代码。 –
文件'“/ tmp/test”'是否存在？ –
