An internal error occurred during: “Start Ruble bundle manager”
问题 I've install the Aptana3 Eclipse plugin, I am using eclipse Version: Juno Service Release 1 Build id: 20121004-1855. Each time I launch eclipse I see an error dialog that says: An internal error occurred during: "Start Ruble bundle manager". java.lang.NullPointerException How can I fix this error? 回答1: I was having the same problem after a fresh install of Eclipse and Aptana. What fixed it for me was very close to what Jason mentioned in his Answer. I checked the available software sites in
