如何在Hyperledger Angular應用程序中啟用身份驗證

Question

通過成功完成本教程，我已將Hyperledger作曲家區塊鏈部署到多個組織。

我已經通過使用命令yo hyperledger-composer:angular通過選擇選項使用現有網絡並生成新的rest api生成了angular2應用程序。

當我啟動應用程序時，它成功了，我可以使用URL http：// localhost：4200從hyperledgercomposer瀏覽資產和參與者。

現在，我想通過遵循本教程並按如下所示編輯angular2應用程序的package.json文件來啟用已安裝passport-github和配置導出選項的其余身份驗證，以便在啟動時啟用身份驗證

 "app": "composer-rest-server --card admin@some-network -n never -p 3000 -m true"

我添加了-m true選項，以便在使用npm start命令啟動angular2應用程序時默認啟用身份驗證。

當我啟動應用程序時，出現以下錯誤。 如何解決呢？
