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。我錯了什麼？IO錯誤：在irb中關閉流
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

爲我工作,,,！ –
請參閱[這裏]（http://www.ruby-doc.org/core-1.9.3/IOError.html），以瞭解何時會出現這樣的錯誤。但我沒有看到任何此類症狀你的代碼。 –
文件'「/ tmp/test」'是否存在？ –
