Can't open new projects in Aptana Studio 3

问题

I tried the operations as you can see at the image below. Can you please help me to set up ruby/rails, so I can learn that popular technology.

EDIT: There must be an error in my settings with ruby/rails so aptana can't access rails. I have used railsinstaller for windows. rails folder exists under gems folder, so rails should be installed.

EDIT2: It may be proxy settings!?

回答1:

If you are behind a proxy try

export HTTP_PROXY=http://yourproxy:port or export HTTP_PROXY=username:password@yourproxy:port before trying to install the gem.
