运行https://github.com/winsonwq/viff-examples上的demo报错

[kangjy]

js如下：
'use strict'
var config = module.exports = {
seleniumHost: 'http://localhost:4444/wd/hub',
browsers: ['chrome'],
envHosts: {
build: 'http://localhost:80/example/build',
prod: 'http://localhost:80/example/prod'
},
paths: [],
reportFormat: 'file',
test: function test (description, caseConfig) {
var c = {};
c[description] = caseConfig;
this.paths.push(c);
}
};
config.test('Home Page', ['/github.html', function (browser) {
return browser.waitForElementByCssSelector('.repo-list-item', browser.isDisplayed());
}]);
config.test('Search Result', ['/github.html', function (browser) {
return browser
.waitForElementByCssSelector('.repo-list-item', browser.isDisplayed())
.elementByCssSelector('[type="search"]').type('commander.js')
.sleep(1000);
}]);
config.test('Open Readme file', ['/github.html', function (browser) {
return browser
.waitForElementByCssSelector('.repo-list-item', browser.isDisplayed())
.elementByCssSelector('.repo-list-item:nth-child(2)').click()
.waitForElementByCssSelector('.repo-readme', browser.isDisplayed());
}])

报错信息如下：
