我尝试在docker机器上运行selenium测试（Node Js），但它说“TypeError: module.exports.browser.isElementPresent is not a function”。
注意：
root@6cd7ab2eb6f7:/usr/src# npm run kongaezv2
npm info it worked if it ends with ok
npm info using npm@4.1.2
npm info using node@v7.6.0
npm info lifecycle cerebro@0.0.1~prekongaezv2: cerebro@0.0.1
npm info lifecycle cerebro@0.0.1~kongaezv2: cerebro@0.0.1
