內做

git checkout REL-1.7.0

只需按照高級安裝： http://sproutcore.com/install_mac/#tab=advanced-install 它會解決它。如果您沒有git（高級安裝的第1點），則不推薦使用第三行。使用「bash -s stable < <（curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer）」而不是「./rvm-installer --version latest」。

謝謝，這工作！ –

服務器無法找到SproutCore的來源。嘗試創建一個框架目錄（與apps目錄並行），並將git clone sproutcore放入其中。然後從您的項目中執行以下操作。

rm -rf tmp 
sc-server

你不應該做到這一點。構建工具應該（過去）有他們自己使用的SC副本。

我在這裏的解決方案是隻指定自己的SC源代碼庫（通過將其放在框架中）並且sc-server應該可以找到它。現在您可以對源代碼進行修改，並且它們將用於您的項目中。你也可以用這種方式切換sproutcore的版本;例如您可以從frameworks/sproutcore目錄

作爲替代方案，您可以嘗試通過'gem install sproutcore'將sproutcore安裝爲gem，然後查看是否修復它。 –

在Lion上運行安裝程序後，將sproutcore安裝爲gem實際上是爲我工作的。 – program247365
