webdriver-io - 安装后 WebdriverIO Chromedriver 服务失败

Question

我是 webdriverIO 的初学者。在网络驱动程序 IO 文档的帮助下，我开始使用 TestRunner。我安装了 node 并得到了对这个命令的预期响应

./node_modules/.bin/wdio --help

我使用

定义了配置

 ./node_modules/.bin/wdio config

但是当我运行的时候

./node_modules/.bin/wdio wdio.conf.js

它给我以下错误

Error: Couldn't initialise launcher from service "chromedriver".

我以前遇到过这个问题。它归结为 wdio-chromedriver-service 没有安装 chromedriver 作为依赖项。

要解决此问题，只需运行:npm i chromedriver --save-dev
