我们有一个 Angular 4 项目，我们正在尝试使用 gulp、nightwatch 和 cucumber 添加一些 e2e 测试，但每次运行测试时都会发生以下错误：

$ gulp e2e-tests
[11:15:12] Using gulpfile ~project/path/gulpfile.js
[11:15:12] Starting 'e2e-tests'...
[11:15:12] Starting 'e2e-scenarios'...
[11:15:12] log file
[11:15:12] Starting nightwatch...
Starting selenium server... started - PID:  18742

There was an error while starting the test runner:

Error: Cannot find module 'e2e/step_definitions/xxxx.js'
    at Function.Module._resolveFilename (module.js:555:15)
    at Function.Module._load (module.js:482:25)
    at Module.require (module.js:604:17)
    at require (internal/module.js:11:18)
    at /project/path/node_modules/cucumber/lib/cli/index.js:163:16
    at Array.forEach (<anonymous>)

下面是我们的配置：

nightwatch.conf

var seleniumServer = require('selenium-server');
const chromedriver = require('chromedriver');

require('nightwatch-cucumber')({
  cucumberArgs: ['--require', 'e2e/step_definitions', '--format', 'json:reports/cucumber.json', 'e2e/features']
});

module.exports = {
    // Loads nightwatch-cucumber configuration into main nightwatch.js conf
    custom_commands_path: '',
    custom_assertions_path: '',
    page_objects_path: '',
    live_output: false,
    disable_colors: false,


    // Sets configuration for Selenium Server
    selenium: {
        start_process: true,
        server_path: seleniumServer.path,
        host: '127.0.0.1',
        port: 4444,
        cli_args : {
            "webdriver.chrome.driver" : chromedriver.path
          }
    },

// Sets config options for different testing environments defined by the user
test_settings: {
    default: {
        launch_url: '',
        selenium_port: 4444,
        selenium_host: '127.0.0.1',
        silent: true,
        desiredCapabilities: {
            browserName: 'chrome',
            javascriptEnabled: true,
            acceptSslCerts: true
        },
        'screenshots': {
            enabled: true,
            on_error: true,
            on_failure: true,
            path: '/screenshots'
        }
    },
    chrome: {
        desiredCapabilities: {
            browserName: 'chrome',
            javascriptEnabled: true,
            acceptSslCerts: true
        }
    }
}
};

    skipTags = '--skiptags ' + skipTags;

  return gulp.src('')

gulp.task('e2e-report', function () {
  return gulp.src('./reports/cucumber.json')
    .pipe(reporter({
      dest: 'reports/'
    }));
});

gulp.task('e2e-tests', function (done) {
  runSequence('e2e-scenarios', 'e2e-report', function () {
    done();
  });
});
