当我运行wdio-runner时，我得到了"wdio-cli:无法识别来自worker的消息“警告消息。

Question

我对WebdriverIO & Cucumber有个问题。

我使用了最新版本的WebdriverIO (@v5.x.x)和黄瓜v4。当我运行测试套件时，控制台会显示一条警告消息。此外，进程中没有创建Cucumber .json数据文件。

警告信息：

警告wdio-cli:无法识别来自worker的消息：

这是我的package.json文件：

  "dependencies": {
    "@wdio/allure-reporter": "^5.4.16",
    "@wdio/cli": "^5.4.17",
    "@wdio/local-runner": "^5.4.17",
    "@wdio/selenium-standalone-service": "^5.4.14",
    "@wdio/spec-reporter": "^5.4.15",
    "chai": "^4.2.0",
    "cucumber": "^4.0.0",
    "moment": "^2.24.0",
    "wdio-cucumber-framework": "^2.2.8",
    "webdriverio": "^5.4.17"
  },
  "devDependencies": {
    "@babel/cli": "^7.2.3",
    "@babel/core": "^7.2.2",
    "@babel/preset-env": "^7.3.1",
    "@babel/register": "^7.0.0"
  },

这里是控制台输出：

我发现了我的错误。

下面解释为什么黄瓜不运行在wdio V5上

要使用黄瓜，必须使用WebdriverIO v4，直到框架迁移到v5为止。
