I'm using Mac OS-X Lion, have Ruby on Rails 3.0 already preinstalled and doing the Getting Started Tutorial for Sproutcore (http://sproutcore.com/guides/getting_started.html). When I run the server and hit: http://localhost:4020/todos. I get the follow error in my terminal: 

   bash-3.2# sc-server

Soluzione

Simply follow the Advanced Install: http://sproutcore.com/install_mac/#tab=advanced-install It will fix it. If you don't have git (point 1 of the advanced installation) the third row is deprecated. Use "bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer ) " instead of "./rvm-installer --version latest".

Altri suggerimenti

The server can't find the sproutcore source. Try creating a frameworks directory (parallel with the apps directory), and git clone sproutcore into it. Then do the following from within your project.

rm -rf tmp
sc-server

You shouldn't have to do this. The build tools should (used to) have their own copy of SC that they use.

What my solution here is is to just specify your own SC source base (by putting it in frameworks) and sc-server should find that. Now you can make modifications to the source and they will be used in your project. You can also switch versions of sproutcore this way; e.g. you can do

git checkout REL-1.7.0

from within the frameworks/sproutcore dir
