调用FileUtils.touch(f)时Windows 7中的utime权限被拒绝 [英] utime permission denied in windows 7 when call FileUtils.touch(f)

问题描述

我正在Windows 7上使用ruby 2.0(不幸的是，我必须这样做)，并且此代码有问题:

I'm working with ruby 2.0 on windows 7 (unfortunately I have to) and have issue with this code:

FileUtils.touch(file)

此代码是更新file.ctime所必需的(可能也会出现问题) 因此，在处理文件时，我会触摸"它们，而不在下一次迭代中对其进行处理.

This code is needed to update file.ctime (which probably will have problems too) So, when files is processed I 'touch' them and not processing them in next iteration.

如何处理错误?

ruby_path/fileutils.rb:1137:in 'utime': Permission denied 'path_to_file' Errno::EACCES
'block in touch'
'each'
'touch'

示例:

file = File.new('file_path')
FileUtils.mkdir_p(path)
FileUtils.cp(file.path, path)
FileUtils.touch(file)

推荐答案

我使用ruby 1.9和2.0进行了测试. FileUtils.touch可以正常工作.

I tested with ruby 1.9 and 2.0. FileUtils.touch works without problems.

您可以提供MWE吗?您是否检查了要检查文件的权限.

Can you provide a MWE. Did you check the permissions on the file you want to check.

特别是:您确定不触摸目录吗?

Especially: Are you sure, you don't touch a directory?

如果您不想检查目录，则可以通过FileUtils.save_touch扩展FileUtils:

If you don't want to check for directories, you may extend FileUtils by FileUtils.save_touch:

require 'fileutils'    
module FileUtils
  def self.save_touch(fpath)
    FileUtils.touch(fpath) unless File.directory?(fpath)
  end
end

FileUtils.save_touch(Dir.pwd)

问题更新后:

After update of question:

FileUtils.touch具有一个参数:文件名或文件路径.

FileUtils.touch has one parameter: a file name or path to a file.

您必须调整示例:

file = File.new('file_path')
FileUtils.mkdir_p(path)
FileUtils.cp(file.path, path)
FileUtils.touch(file.path)
