當我試圖部署node.js應用程序（同時使用nodejitsu和heroku）時，我得到了與libxmljs相同的錯誤。libxmljs：找不到scons命令

正如你所看到的，它是libxmljs的「接通節點」中失敗，「使乾淨」的命令「scons的」未找到。我的應用程序的node_modules目錄中安裝了libxmljs，'scons'位於「/ usr/local/bin/scons」。
我相信我必須確保scons的位置在libxmljs make環境的路徑中，但我不知道該怎麼做。任何幫助，將不勝感激！
UPDATE：在從這個問題（Fail to deploy node.js application to heroku）的意見，我加入libxmljs到的package.json，並添加node_modules /到的.gitignore的依賴關係，這樣的Heroku可以看看的依賴關係，並安裝它們自己。但是，發生了完全相同的錯誤，這使我相信問題的根源不在我的本地環境中，而是關於libxmljs更大的問題？
