使用量角器运行脚本时获取“驱动程序信息：driver.version：未知”

Question

在量角器中执行脚本时出现以下错误。

System info: host: '8888', ip: '88888', os.name: 'Mac OS X', os.arch: 'x86_64', os.version: '10.15.7', java.version: '14.0.1'
Driver info: driver.version: unknown
[13:13:08] E/launcher - WebDriverError: Timed out waiting for driver server to start.
Build info: version: '3.141.59', revision: 'e82be7d358', time: '2018-11-14T08:25:53'

谁能帮帮我。

Answer 1

由于新的 m1 芯片组下载了错误的 ChromeDriver

由于新的 m1 芯片组，我们正在下载错误版本的 ChromeDriver。有一个写成 https://github.com/angular/webdriver-manager/pull/478 的修复程序，我将在本周末将其发布到 npm。

更新：npm 发布为 12.1.8 版

如何更新到 webdriver-manager 12.1.8？你可以做一个npm install --force protractor。这应该会更新您的依赖项。您也可以清除您的 node_modules/ 目录并重新创建 npm install

这已作为版本 12.1.8 发布到 npm。更新到版本 12.1.8 后，您可能需要先运行 webdriver-manager clean，然后再运行 webdriver-manager update。

Answer 2

从昨天开始，我也遇到了同样的问题。 我还尝试重新安装操作系统干净，只安装节点和铬。还是行不通。我认为这与 chromedriver 或新的 chrome 版本有关。

对我来说，这发生在 Mac 最新的 Catalina 补丁上。在两个不同的 linux 机器上它工作得很好。
