我做了教程，使用IoT Foundation Service和.js樣板可視化我的樹莓派中的數據。Bluemix Single Sign On不顯示登錄頁面
我也跟着下面的教程：
https://developer.ibm.com/recipes/tutorials/visualizing-your-data/
，一切工作正常。
現在我嘗試添加單點登錄服務進行身份驗證。我創建了一個雲註冊表並添加了兩個測試用戶。之後，我將服務綁定到我的物聯網可視化.js應用程序，並執行將我的應用程序與服務集成的步驟。我跟着官方文檔步驟執行這一（點「配置的Node.js應用程序」）：
我修改了我的電腦上的文件和使用CL CLI上載他們。問題是，它沒有改變任何東西。我可以像以前一樣訪問我的應用程序，但沒有看到任何登錄頁面。
這裏是我的文件：

任何想法？

有沒有.cfignore文件時，我第一次開始教程。所以，我創建了一個在我的應用程序的根文件夾下面的內容：
node_modules/passport
node_modules/cookie-parser
node_modules/express-session
node_modules/passport-idaas-openidconnect
這是正確的，爲什麼我沒有與本教程內容之前有這樣的文件：
node_modules
我認爲您的問題可能與Bluemix維護在構建之間保留的緩存目錄有關。此緩存用於存儲解析的依賴關係，因此不必在每次部署時都下載並安裝它們。您可能需要覆蓋此設置，並通過將NODE_MODULES_CACHE設置爲false來禁用它，以便部署更新的依賴項。我已經要求我的同事審查您的帖子並進一步發表評論。 – ValerieLampkin
@ValerieLampkin雖然它確實使用緩存，但Bluemix將始終使用新的package.json運行'npm install'。 NPM識別出緩存缺少新添加的模塊並將安裝它。無論如何，如果模塊不在那裏，應用程序會崩潰，說模塊不存在。 –
好吧，所以我不需要將NODE_MODULES_CACHE設置爲false？我還編輯了關於.cfignore文件的第一篇文章。 – Jenkins
