标题: 脚本创建多级文件夹的问题
首先，我先说明创建文件夹就是多级文件夹
一共两级
然后我用的代码是这个（只贴一段

[pre lang="ruby" line="58"] class Game_KankageSimbo

  #--------------------------------------------------------------------------
  # ● 开始处理
  #--------------------------------------------------------------------------
  def start

if Dir.glob(Path::BASIC + Path::NAME).empty?
   FileUtils.mkdir_p(Path::BASIC + Path::NAME)
end

if Dir.glob(Path::BASIC + Path::NAME + Path::SAVE).empty?
   Dir.mkdir(Path::BASIC + Path::NAME + Path::SAVE)
end

if Dir.glob(Path::BASIC + Path::NAME + Path::PATCH).empty?
   Dir.mkdir(Path::BASIC + Path::NAME + Path::PATCH)
end


  end


end


  #--------------------------------------------------------------------------
  # ● 开始执行
  #--------------------------------------------------------------------------

  Game_KankageSimbo.new.start

[/pre]
上面的Path::BASIC等等都是路径
然后这个就出错了
(, 下载次数: 66)

这是我ruby来的FileUtils函数的用法

FileUtils.mkdir_p( dir, *options )
Options: noop verbose

将生成dir目录及其所有上级目录。
例如

FileUtils.mkdir_p '/usr/local/lib/ruby'

将生成下列所有目录(若没有的话)。
* /usr
* /usr/local
* /usr/local/bin
* /usr/local/bin/ruby

然后求大神解决

RGSS 并没有 fileutils 库，Ruby 才有……

你可以选择如下方法：
将 fileutils 标准库直接复制到 RM 中使用。我家是 Ruby 2.2 的，代码如下（未测试，不保证能用）：

# FileUtils.chown(user, group, list, options)
# FileUtils.chown_R(user, group, list, options)

#
# The <tt>options</tt> parameter is a hash of options, taken from the list
# <tt>:force</tt>, <tt>:noop</tt>, <tt>:preserve</tt>, and <tt>:verbose</tt>.
# <tt>:noop</tt> means that no changes are made. The other two are obvious.
# Each method documents the options that it honours.
#
# All methods that have the concept of a "source" file or directory can take
# either one file or a list of files in that argument. See the method
# documentation for examples.
#
# There are some `low level' methods, which do not accept any option:
#

# FileUtils.copy_file(src, dest, preserve = false, dereference = true)
# FileUtils.copy_stream(srcstream, deststream)

# FileUtils.remove_entry_secure(path, force = false)
# FileUtils.remove_file(path, force = false)
# FileUtils.compare_file(path_a, path_b)
# FileUtils.compare_stream(stream_a, stream_b)
# FileUtils.uptodate?(file, cmp_list)
#
# == module FileUtils::Verbose
#
# This module has all methods of FileUtils module, but it outputs messages
# before acting. This equates to passing the <tt>:verbose</tt> flag to methods
# in FileUtils.
#
# == module FileUtils::NoWrite
#
# This module has all methods of FileUtils module, but never changes
# files/directories. This equates to passing the <tt>:noop</tt> flag to methods
# in FileUtils.
#
# == module FileUtils::DryRun
#
# This module has all methods of FileUtils module, but never changes

2. 自己重定义一下 mkdir_p 。要求不是太高的话应该不会太难，就是一些简单的字符串操作而已。
我写过类似的代码，但是代码的目的是在不存在的文件夹创建文件。代码未整理成方法，也没有测试和查错，仅供参考：
[pre lang="ruby"]
# filename：目标文件
paths = File.dirname(filename).split('/') # 要求使用正斜杠(/)
1.upto(paths.size) do |i|
 dir = paths.first(i).join('/')
 Dir.mkdir(dir) unless Dir.exist?(dir)
end
[/pre]
