Question

我试图运行这个关于环回的CoffeeShop示例：

http://loopback.io/doc/en/lb2/Create-AngularJS-client.html

在与AngularJS集成时出现错误似乎没问题

使用以下命令时：

lb-ng server/server.js client/js/services/lb-services.js

我得到了错误堆栈：

Loading LoopBack app "/home/dqlgnoleht/Working/Projects/loopback-getting-started/server/server.js"
/home/dqlgnoleht/Working/Projects/loopback-getting-started/node_modules/async/dist/async.js:1340
        return fn.apply(null, args.concat(callArgs));
                 ^

TypeError: Cannot read property 'apply' of undefined

    at _parallel (/home/dqlgnoleht/Working/Projects/loopback-getting-started/node_modules/async/dist/async.js:3827:9)

如何正确运行？或者我只是错过了一些配置。请帮忙！

非常感谢您的任何帮助！

您应该返回一个返回异步函数的函数。它可能是这样的：

<强>模型/ candidate.js

module.exports = function (Candidate) {

  Candidate.getRawCV = getRawCV(Candidate);

  function getRawCV (Candidate) {
    return async function (next) {
      ...async code...
    }
  }

}

lb-ng loopback命令从异步模块返回“无法读取属性'应用'未定义”
