拼音FileUtils.mkdir错误

Question

我正在尝试写一个程序来制作一个文件夹的大约100个副本，每个副本都有不同的名称，但在相同的目录中。以下是我到目前为止拥有的代码：

require 'fileutils'

filename = "C:/Users/drwat/Desktop/somefolder/accountusernames.txt"
times = IO.readlines(filename).size
counter = 0
password = "changethis"

originalFolder = "Release/."

while(counter < times)
    begin
        currentusername = IO.readlines(filename)[counter]

        FileUtils.mkdir currentusername
        FileUtils.cp_r(originalFolder, "#{currentusername}")

        #Put username into auth.json file
        data = File.read("auth.json")
        filtered_data = data.gsub("aaaa", "#{currentusername}")
        File.open("auth.json", "w") do |f|
            f.write(filtered_data)
        end

        #Put password into auth.json file
        data = File.read("auth.json")
        filtered_data = data.gsub("bbbb", "#{password}")
        File.open("auth.json", "w") do |f|
            f.write(filtered_data)
        end

        FileUtils.cp "auth.json", "#{currentusername}/Config"

        #Revert auth.json file back to A's and B's
        data = File.read("auth.json")
        filtered_data = data.gsub("#{currentusername}", "aaaa")
        File.open("auth.json", "w") do |f|
            f.write(filtered_data)
        end
        data = File.read("auth.json")
        filtered_data = data.gsub("#{password}", bbbb)
        File.open("auth.json", "w") do |f|
            f.write(filtered_data)
        end

        counter += 1
    end
end

当我运行程序时，我得到的错误：

D:/Installed Programs/Ruby200-x64/lib/ruby/2.0.0/fileutils.rb:245:in `mkdir': Invalid argument - twitchypair1 (Errno::EINVAL)
        from D:/Installed Programs/Ruby200-x64/lib/ruby/2.0.0/fileutils.rb:245:in `fu_mkdir'
        from D:/Installed Programs/Ruby200-x64/lib/ruby/2.0.0/fileutils.rb:174:in `block in mkdir'
        from D:/Installed Programs/Ruby200-x64/lib/ruby/2.0.0/fileutils.rb:173:in `each'
        from D:/Installed Programs/Ruby200-x64/lib/ruby/2.0.0/fileutils.rb:173:in `mkdir'
        from D:/somefolder/thiscode.rb:14:in `<main>'

我不知道是不是我的代码或者ruby的安装出了什么问题。我尝试了几种不同的方法来使其工作，例如删除FileUtils.mkdir行，但我无法获得它。这又给了我一个错误。任何帮助都将不胜感激。我对Ruby并没有做太多的工作，但是除了这个之外，它似乎非常容易使用。

同样，"#{ currentusername }“和currentusername返回的是完全相同的东西吗？

所以，像这样的东西应该是有效的：

require 'fileutils'

filename = "C:/Users/drwat/Desktop/somefolder/accountusernames.txt"
times    = IO.readlines(filename).size
counter  = 0
password = "changethis"

originalFolder = "Release/."

IO.readlines(filename).chomp.each \
{|currentusername|
    FileUtils.mkdir currentusername
    ...
}

正如我前面提到的，在文件中截取()数据以从源数据中删除回车符/换行符几乎总是一个好主意。
