You can also use FileUtils#cdmethod.
您也可以使用FileUtils#cd方法。
Changes the current directory to the directory dir.If this method is called with block, resumes to the old working directory after the block execution finished.
将当前目录切换到目录dir。如果用block调用此方法，则在block执行完成后恢复到旧的工作目录。
Example( I am on windows-7) :
示例（我在 windows-7 上）：
require 'fileutils'
Dir.pwd # => "C:/Program Files/Notepad++"
FileUtils.cd("C:\Users\rakshiar\Downloads")
Dir.pwd # => "C:/Users/rakshiar/Downloads"
