package.json 中的量角器版本相同，安装不同的 chrome 驱动程序版本？

Question

我对量角器版本及其工作原理感到困惑。 所以我创建了两个不同的节点项目，我在两个项目中都使用量角器版本"protractor": "~5.4.0"。

当我尝试运行命令 npm run e2e 时，一个项目正在安装 chrome 驱动程序版本 2.46

当我提供相同的量角器版本时，这怎么可能？ 有人可以帮我理解这个过程并帮助我克服这个问题吗？

Answer 1

旧版本的 webdriver-manager

这意味着您在第一个旧项目中有一个 webdriver-manager 节点模块。下载 chromedriver 2.46 不再适用于最新版本的 Chrome。

Protractor ~5.4.x package.json 依赖项需要 webdriver-manager ^12.x.x。这意味着它将下载任何次要版本更新。因此，对于测试的较新安装，您将下载较新版本的 webdriver-manager。这些更高版本对 Chrome 浏览器主要版本进行了修复。目前最新的应该是 ChromeDriver 的 76 版本。

尝试下载正确版本的 ChromeDriver

假设您仍然需要 chromedriver 2.46 版，因为您仍在运行 Chrome 73 版（我认为这是它支持的 Chrome 版本），那么您可以通过webdriver-manager update --versions.chrome 2.46 获得它。同样，如果您需要版本 75，您可以从 https://chromedriver.storage.googleapis.com 下载特定版本。因此，您可以运行 webdriver-manager update --versions.chrome 75.0.3770.90 并下载该特定版本。

这会好转吗？

是的。有一些修复，但当前的 webdriver-manager 版本 12 没有提供支持。Protractor 6 很快就会采用一些重大更改......当它（最终）推出时。
