推荐答案

在Ruby中,Linux或Windows中的路径没有区别.无论环境如何,路径都应使用/.因此,要在Windows中使用任何路径,请将所有\替换为/. File#join适用于Windows和Linux.例如,在Windows中:

In Ruby, there is no difference between the paths in Linux or Windows. The path should be using / regardless of environment. So, for using any path in Windows, replace all \ with /. File#join will work for both Windows and Linux. For example, in Windows:

Dir.pwd
=> "C/Documents and Settings/Users/prince"

File.open(Dir.pwd + "/Desktop/file.txt", "r")
=> #<File...>

File.open(File.join(Dir.pwd, "Desktop", "file.txt"), "r")
=> #<File...>

File.join(Dir.pwd, "Desktop", "file.txt")
=> "C/Documents and Settings/Users/prince/Desktop/file.txt"
