使用require

Question

在Javascript中使用require函数时，我遇到了MultipleDefine错误。我正在使用Karma，Dojo和Cucumber-js。我之前从未见过此错误，而且我真的不确定这是什么意思或如何解决！请帮忙。

我在stackoverflow上看到了类似的问题，但是它们都与esri或arcgis有关，与我正在使用的东西相去甚远。

这是我的黄瓜和业力整合的步骤文件。在我使用require添加第二行之前，一切工作正常。

'use strict';
var calc = require('../../../../../lib/calculator');
Before("@test", function(scenario) {
    expect(["Test scenario 2.1", "Test scenario 1.3"].indexOf(scenario.pickle.name) !== -1).to.equal(true);
});
Given(/^there is a test step$/, function () { });
Given(/^there is an ambiguous test step$/, function () { });
When(/^it is executed$/, function () { });
When(/^it is not executed$/, function (callback) { return callback(null, 'pending'); });
Then(/^test succeeds$/, function () { });
Then(/^test fails$/, function (callback) { return callback(new Error("Step failed") ); });

我收到此错误消息：
