Selenium 无法运行量角器测试

我已经执行了

npm安装-g量角器

，还通过

webdriver manager update

命令更新了驱动程序

执行

webdriver-manager-start

后，服务器启动，但一开始它会给我一些奇怪的输出。我怀疑这个错误会导致我的主要错误——无法执行测试

有趣的是，我坐在一个代理后面，不得不用

--proxy

选项安装/更新驱动程序。此外，我也无法在hub

http://localhost:4444/wd/hub/

对于

webdriver manager启动

错误，请尝试指定代理，如执行

更新

。如果您没有为start cmd指定驱动程序版本，webdriver manager将从internet查询最新版本，如果您的本地用户有，则跳过下载。因此，当不告诉版本显式使用start cmd时，它需要访问internet。如果上述方法修复了启动问题，则创建会话的第二个问题与启动问题无关。这主要是因为您的chrome浏览器与chrome webdriver不兼容。如果是，请找出兼容的chrome webdriver版本，并在webdriver管理更新和启动cmd中指定chrome webdriver版本。对于
