如何在Hyperledger Angular应用程序中启用身份验证

Question

通过成功完成本教程，我已将Hyperledger作曲家区块链部署到多个组织。

我已经通过使用命令yo hyperledger-composer:angular通过选择选项使用现有网络并生成新的rest api生成了angular2应用程序。

当我启动应用程序时，它成功了，我可以使用URL http：// localhost：4200从hyperledgercomposer浏览资产和参与者。

现在，我想通过遵循本教程并按如下所示编辑angular2应用程序的package.json文件来启用已安装passport-github和配置导出选项的其余身份验证，以便在启动时启用身份验证

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

我添加了-m true选项，以便在使用npm start命令启动angular2应用程序时默认启用身份验证。

当我启动应用程序时，出现以下错误。 如何解决呢？
