ruby:`read':File.read上的参数无效 - (Errno :: EINVAL)

Question

我正在做一个简单的脚本来检查所有文件的crc ...

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
}

问题出在File.read('dir.txt').each_line { |line| 我收到此错误的行:

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是"dir.txt"中列出的文件.

您是否检查过该行不包含额外字符？p line.

IIRC line将包含换行符,使用line.chomp.
