使用WebDrivero&；运行案例时调用安装脚本；selenium独立服务

我正在使用WebDrivero和selenium单机版（chrome）进行测试。但我每次都会犯以下错误。似乎在运行案例（selenium或chromedriver）时调用了安装脚本。但是已经安装了selenium独立服务器和chrome驱动程序。我从

“java-jar selenium-server-standalone-3.141.5.jar”

开始。此外，色度驱动器为2.34

[li@localhost webdriverio-test]$ ./node_modules/.bin/wdio wdio.conf.js

为什么在运行案例时调用安装脚本？

找到解决方案了吗？我们遇到同样的问题。测试正在运行，但TLS连接失败通常需要20秒。我们支持一个公司代理，并且似乎没有使用代理设置启动wdio的选项
