SessionNotCreatedError：量角器自动化中未创建会话错误答案

【问题标题】：SessionNotCreatedError: session not created Error in Protractor automationSessionNotCreatedError：量角器自动化中未创建会话错误

【问题描述】：

我有一个 Angular 应用程序，我正在尝试对其运行 Protractor 自动化测试。但是当我尝试运行自动化测试时，我收到以下错误。我有 Chrome 浏览器 86 并将 chrome 86 chromedriver.exe 放在 node_moules/protractor/selenium/ 下。但我仍然收到以下错误。

不知道在哪里设置要求量角器拾取 chrome86 驱动程序的路径。任何帮助表示赞赏。

【解决方案1】：

无需下载每个新版本的 chromedriver 即可自动执行此操作，就是让 webdriver-manager 包完成其工作。

node node_modules/protractor/bin/webdriver-manager update
protractor <your_configuration_js>

注意：请参阅上面如何调用 webdriver-manager，它使用项目 npm 模块中的本地版本（而不是全局版本）。它可以很好地同步以下设置。

如果您在 量角器配置 上使用了上述步骤，则必须启用此键。这不需要在每次开始测试时使用/执行webdriver-manager start。

directConnect: true

【解决方案2】：

当我将 protractor/config.json 更改为指向 86 的最新 chromedriver 时，我能够解决问题

{
  "webdriverVersions": {
    "selenium": "2.52.0",
    "chromedriver": "86.0.4240.22",
    "iedriver": "2.52.0"
  }
}

然后手动下载文件放到protractor/selenium中，把扩展名改成chromedriver_86.0.4240.22.exe
