Question

我尝试使用量角器进行某些e2e测试，之前从未使用过它。该项目是使用yeoman-gulp-angular生成的，并且有一些预定义的测试任务/配置。当我尝试执行任务时，我看到selenium已经启动，然后堆栈跟踪在selenium关闭之前输出一些错误。配置中是否缺少某些内容？

量角器配置

'use strict';

var paths = require('./.yo-rc.json')['generator-gulp-angular'].props.paths;

// An example configuration file.
exports.config = {
  // The address of a running selenium server.
  //seleniumAddress: 'http://localhost:4444/wd/hub',
  //seleniumServerJar: deprecated, this should be set on node_modules/protractor/config.json

  // Capabilities to be passed to the webdriver instance.
  capabilities: {
    'browserName': 'chrome'
  },

  // Spec patterns are relative to the current working directly when
  // protractor is called.
  specs: [paths.e2e + '/**/*.js'],

  // Options to be passed to Jasmine-node.
  jasmineNodeOpts: {
    showColors: true,
    defaultTimeoutInterval: 30000
  }
};

更新

我认为事情是固定的，但事实并非如此。运行webdriver-manager update然后webdriver-manager status后，我看到chromedriver version available: 2.27 [last]。当我查看node_modules / protractor / selenium时，我看到chromedriver_2.12.zip。在node_modules / protractor / config.json中，我将chromedriver的webdriverVersions从2.12更改为2.27，这是不可用的。不确定我应该在protractor /config.json中指定哪个版本。
