ruby: `read': Invalid argument -(Errno::EINVAL) at File.read

问题:

I'm doing a simple script to check crc of all files...

require "zlib" exit if Object.const_defined?(:Ocra)  files = Dir.glob("*")  File.open('dir.txt', 'a+') do |file|    file.puts files end  File.read('dir.txt').each_line { |line|     file = File.read(line) ; nil     file_crc = Zlib.crc32(file,0).to_s(16)     puts line, file_crc } 

The problem is at the line File.read('dir.txt').each_line { |line| I get this error:

test.rb:13:in `read': Invalid argument - 1.exe (Errno::EINVAL)         from C:/Users/Administrador/Desktop/1.rb:13:in `block in <main>'         from C:/Users/Administrador/Desktop/1.rb:12:in `each_line'         from C:/Users/Administrador/Desktop/1.rb:12:in `<main>' 

PD: 1.exe is a file listed in the "dir.txt".

回答1:

Have you checked that the line doesn't contain extra characters? p line.

IIRC line will contain the newline character, use line.chomp.
