[英]bluemix node-red flow editor “deploy” button is not enabled
我正在学习教程：“在5分钟内使用Node-RED构建实时聊天应用程序” http://www.ibm.com/developerworks/cloud/library/cl-rtchat-app/
但是未启用“部署”按钮。 所以我无法部署。
我已经安装了CF命令行并为我的应用程序运行“ push”。 这是我从仪表板“ CFApp”下的“开始编码”中学到的。 成功了
这个“推送”与Node-Red编辑器中的“部署”相同吗？
谢谢。

该教程的编辑器屏幕截图有些误导，带有空白工作区和已启用的部署按钮。 仅当工作区中有尚未部署到运行时的更改时，部署按钮才变为活动状态。
“推”用于将节点红色的应用程序上载到bluemix中。 这与将流部署到应用程序中不同。
部署按钮与CF按钮不同。 节点红色的图形用户界面中提供了节点红色的部署按钮。
创建节点红色应用程序后，必须启动它。
这是教程第1步的项目符号3。 在Bluemix仪表板上，单击应用程序名称以启动它。
将显示节点红色应用程序的主窗口（本教程的步骤1上的项目符号4）。
单击红色大按钮“转到您的节点红色流编辑器”将打开节点红色流编辑器（在步骤1的项目符号5上显示）。 此时，您应该会看到一个空白表，并且应该禁用右上角的“部署”按钮。
按照步骤2的说明导入节点红色流（为方便起见，在下面将其包括在内）：
