如何在Ruby中创建临时目录？

How do I create a temporary directory in Ruby in a nice way? I would also like to delete it automatically on process exit. Thanks!

如何以一种很好的方式在Ruby中创建临时目录？我还想在进程退出时自动删除它。谢谢！

See documentation for tmpdir. If mktmpdir method is provided with a block, the temp dir will be removed when block returns. In your case, you would call without a block and handle removal later (=program exit).

请参阅tmpdir的文档。如果为mktmpdir方法提供了一个块，则在块返回时将删除temp dir。在您的情况下，您将在没有块的情况下调用并稍后处理删除（=程序退出）。

Regarding automatic removal on exit, I think tmpdir won't do that for you. However, at_exit should help.

关于退出时自动删除，我认为tmpdir不会为你做那件事。但是，at_exit应该有所帮助。

As an example, Homebrew does it like this:

举个例子，Homebrew就是这样的：

require 'tmpdir'

# rest omitted

TEST_TMPDIR = ENV.fetch("HOMEBREW_TEST_TMPDIR") do |k|
  dir = Dir.mktmpdir("homebrew-tests-", ENV["HOMEBREW_TEMP"] || "/tmp")
  at_exit { FileUtils.remove_entry(dir) }
  ENV[k] = dir
end

Use the Dir.mktmpdir method, from the stdlib

使用stdlib中的Dir.mktmpdir方法
