Tempora开发者_Python百科rily enhancing PATH to include DevKit...

Building native extensions.  This could take a while...

After I had installed the DevKit ( http://github.com/oneclick/rubyinstaller/wiki/Development-Kit), I must wait for a long time when I install passenger , (now...It has past 20 minutes) ,why?

Phusion Passenger doesn't support Windows.
