無法解析依賴項 - webdriverIO

Question

我正在嘗試使用 ( npm run test-local ) 運行我的 WebdriverIo 規范，即使我在 package.json 中擁有所有依賴項，我也會收到以下錯誤，如下所述

[0-2] 錯誤：無法創建會話。 錯誤轉發新會話 Empty pool of VM for setup Capabilities {browserName: chrome, goog:chromeOptions: {}}*

npm WARN grunt-webdriver@3.0.0 需要@wdio/cli@^5.1.0 的同級，但沒有安裝。 您必須自己安裝對等依賴項。 npm WARN grunt-webdriver@3.0.0 需要 webdriverio@^5.1.0 的同級，但沒有安裝。 您必須自己安裝對等依賴項。 npm WARN wdio-chromedriver-service@6.0.4 需要 chromedriver@ 的同級，但沒有安裝。 您必須自己安裝對等依賴項。 *

確保 selenium 獨立服務器已啟動並正在運行

java -jar selenium-server-standalone-3.141.59.jar -role node -hub http://localhost:4444/grid/register -browser "browserName=chrome,maxinstance=1

上面的命令對我有用！
