Re: [Pharo-users] SCouchDB install not working in Pharo: "MessageNotUnderstood: receiver of ""mantis"" is nil"

Pharo and Squeak have different mechanisms for this. Pharo doesn't have the Installer class. You might try ConfigurationOfSCouchDB from...

There was this book (and some others of the same ink) that was provided with my first computer: http://www.colorcomputerarchive.com/coco/Documents/Manuals/Hardware/Getting… I actually had the french version. http://www.colorcomputerarchive.com/coco/Documents/Manuals/Hardware/Color%2… This thing is still sitting near my desk today (I guess it keeps me connected to my curious young self or something like that). I keep on thinking that it would be great to have a Pharo-based version of it.
