我正在使用Mac OS-X Lion，已经预装了Ruby on Rails 3.0并且正在使用Sproutcore的入门教程（http://sproutcore.com/guides/getting_started.html）。当我运行服务器并点击：http://localhost:4020/todos时。我的终端出现了以下错误：

只需按照高级安装： http://sproutcore.com/install_mac/#tab=advanced-install 它会解决它。 如果您没有git（高级安装的第1点），则不推荐使用第三行。使用“bash -s stable＆lt;＆lt;（curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer） “而不是”./rvm-installer --version latest“。

答案 1 :(得分：1)

服务器找不到sproutcore源。尝试创建一个框架目录（与apps目录并行），并将git克隆sproutcore到其中。然后在项目中执行以下操作。

rm -rf tmp
sc-server

你不应该有来做这件事。构建工具应该（以前）拥有自己使用的SC副本。

我的解决方案是仅指定您自己的SC源代码库（通过将其置于框架中）并且sc-server应该找到它。现在您可以对源进行修改，它们将在您的项目中使用。你也可以用这种方式切换sproutcore的版本;例如你可以做到

git checkout REL-1.7.0

来自frameworks/sproutcore目录
