How do I get the name of the current directory in Ruby? All I've found is File.dirname(__FILE__), but that only returns . and I want the actual name. How do I do this?

dirname = File.basename(Dir.getwd)
File.basename() returns the base name even when its argument is the path of a directory.
basename()返回基名，即使其参数是目录的路径。
To get absolute path, Dir.pwd seems to do the trick.
为了得到绝对路径，Dir。pwd似乎做到了这一点。
