[英]bluemix node-red flow editor “deploy” button is not enabled
我正在學習教程：“在5分鍾內使用Node-RED構建實時聊天應用程序” http://www.ibm.com/developerworks/cloud/library/cl-rtchat-app/
但是未啟用“部署”按鈕。 所以我無法部署。
我已經安裝了CF命令行並為我的應用程序運行“ push”。 這是我從儀表板“ CFApp”下的“開始編碼”中學到的。 成功了
這個“推送”與Node-Red編輯器中的“部署”相同嗎？
謝謝。

該教程的編輯器屏幕截圖有些誤導，帶有空白工作區和已啟用的部署按鈕。 僅當工作區中有尚未部署到運行時的更改時，部署按鈕才變為活動狀態。
“推”用於將節點紅色的應用程序上載到bluemix中。 這與將流部署到應用程序中不同。
部署按鈕與CF按鈕不同。 節點紅色的圖形用戶界面中提供了節點紅色的部署按鈕。
創建節點紅色應用程序后，必須啟動它。
這是教程第1步的項目符號3。 在Bluemix儀表板上，單擊應用程序名稱以啟動它。
將顯示節點紅色應用程序的主窗口（本教程的步驟1上的項目符號4）。
單擊紅色大按鈕“轉到您的節點紅色流編輯器”將打開節點紅色流編輯器（在步驟1的項目符號5上顯示）。 此時，您應該會看到一個空白表，並且應該禁用右上角的“部署”按鈕。
按照步驟2的說明導入節點紅色流（為方便起見，在下面將其包括在內）：
