Question

请帮忙！

你好

我无法进行量角器测试，认为chrome会弹出一个空白页面

在错误消息中显示无法启动webdriver

Answer 1

您是否在测试运行前更新了webdriver-manager？我们试着webdriver-manager update

您是否尝试在节点v6上运行该程序？

Answer 2

通过从代码中删除seleniumAddress: 'http://127.0.0.1:4444/wd/hub',来尝试投放。
安装 LTS 版本的nodejs，而不是安装最新版本。

Answer 3

您必须运行本地量角器安装。

npm install protractor --save-dev

将其添加到package.json：

"scripts": { "update-webdriver": "webdriver-manager update", "protractor": "protractor config.js", },

并运行：

npm run update-webdriver npm run protractor

量角器无法启动webdriver会话
