Ruby deleting directories
提问by Ced
I'm trying to delete a non-empty directory in Ruby and no matter which way I go about it it refuses to work. I have tried using FileUtils, system calls, recursively going into the given directory and deleting everything, but always seem to end up with (temporary?) files such as
我正在尝试删除 Ruby 中的非空目录，无论我采用哪种方式，它都拒绝工作。我曾尝试使用 FileUtils、系统调用、递归进入给定目录并删除所有内容，但似乎总是以（临时？）文件结束，例如
.__afsECFC
.__afs73B9
.__afsECFC
.__afs73B9
Anyone know why this is happening and how I can go around it?
任何人都知道为什么会发生这种情况以及我如何解决它？

Realised my error, some of the files hadn't been closed. I earlier in my program I was using
意识到我的错误，有些文件没有关闭。我早些时候在我的程序中使用
File.open(filename).read
which I swapped for a
我换了一个
f = File.open(filename, "r")
while line = f.gets
puts line
end
f.close
And now
现在
FileUtils.rm_rf(dirname)
works flawlessly
完美无缺

require 'fileutils'
FileUtils.rm_rf('directorypath/name')
Doesn't this work?
这不行吗？

Safe method: FileUtils.remove_dir(somedir)
回答by JonatasTeixeira
I guess the best way to remove a directory with all your content "without using an aditional lib" is using a simple recursive method:
我想“不使用附加库”删除包含所有内容的目录的最佳方法是使用简单的递归方法：
def remove_dir(path)
if File.directory?(path)
Dir.foreach(path) do |file|
if ((file.to_s != ".") and (file.to_s != ".."))
remove_dir("#{path}/#{file}")
end
end
Dir.delete(path)
else
File.delete(path)
end
end
remove_dir(path)
