本文介绍了如何在角度量角器中降级Chrome WebDriver的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试使用chrome作为浏览器在Angular 7上运行 ng e2e .我运行了 npm install -g protractor 和 webdriver-manager update 命令.它最终下载并运行chromedriver = 76.0.3809.12，但是我无法在自己的计算机上更新chrome本身.我在chrome 74上.

我尝试过 webdriver-manger更新， webdriver-manager更新--versions.chrome 2.46 ，以及 webdriver-manager更新--versions.chrome 74.0.3729.6 但即使我去 node_modules \ protractor \ node_modules \ webdriver-manager \ selenium \ 中删除chrome 76文件，但每次运行 ng e2e

protractor.conf.js 

  exports.config = {allScriptsTimeout:11000，眼镜: ['./src/**/*.e2e-spec.ts']，功能:{'browserName':'chrome'}，directConnect:是的，baseUrl:'http://localhost:4200/'，框架:茉莉花"，jasmineNodeOpts:{showColors:true，defaultTimeoutInterval:30000，打印:function(){}}，onPrepare(){require('ts-node').register({项目:require('path').join(__ dirname，'./tsconfig.e2e.json')});jasmine.getEnv().addReporter(new SpecReporter({spec:{displayStacktrace:true}})));}};

tsconfig.e2e.json 

 <代码> {"extends":"../tsconfig.json"，"compilerOptions":{"outDir":"../out-tsc/app"，"module":"commonjs"，"target":"es5"，类型":[茉莉花"jasminewd2"，节点"]}}

当我尝试运行 ng e2e 时，抛出此错误:

  E/启动器-未创建会话:此版本的ChromeDriver仅支持Chrome版本76(驱动程序信息:chromedriver = 76.0.3809.12(220b19a666554bdcac56dff9ffd44c300842c933-refs/branch-heads/3809 @ {#83})，平台= Windows NT 10.0.16299 x86_64)E/启动器-进程退出，错误代码199发生意外错误:未定义

更新:当我运行 webdriver-manager clean 和 node node_modules/protractor/bin/webdriver-manager update --standalone --versions.standalone = 3.8.0 时，它仍然下载了chrome 76这是第二个命令的输出以及clean之后的ng e2e

解决方案

尝试以下选项

  webdriver-manager clean//将清除现有的webdriver节点node_modules/protractor/bin/webdriver-manager更新--standalone --versions.standalone = 3.8.0

I am trying to run ng e2e on Angular 7 with chrome as the browser. I ran the commands npm install -g protractor and webdriver-manager update. It ends up downloading and running chromedriver=76.0.3809.12 but it is not possible for me to update chrome itself on my machine. I am on chrome 74.

I have tried webdriver-manger update, webdriver-manager update --versions.chrome 2.46, and webdriver-manager update --versions.chrome 74.0.3729.6 but even if I go and delete the chrome 76 files from node_modules\protractor\node_modules\webdriver-manager\selenium\ but they always reinstall everytime I run ng e2e

protractor.conf.js

exports.config = {
  allScriptsTimeout: 11000,
  specs: [
    './src/**/*.e2e-spec.ts'
  ],
  capabilities: {
    'browserName': 'chrome'
  },
  directConnect: true,
  baseUrl: 'http://localhost:4200/',
  framework: 'jasmine',
  jasmineNodeOpts: {
    showColors: true,
    defaultTimeoutInterval: 30000,
    print: function() {}
  },
  onPrepare() {
    require('ts-node').register({
      project: require('path').join(__dirname, './tsconfig.e2e.json')
    });
    jasmine.getEnv().addReporter(new SpecReporter({ spec: { displayStacktrace: true } }));
  }
};

tsconfig.e2e.json

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/app",
    "module": "commonjs",
    "target": "es5",
    "types": [
      "jasmine",
      "jasminewd2",
      "node"
    ]
  }
}

when I attempt to run ng e2e it throws this error:

E/launcher - session not created: This version of ChromeDriver only supports Chrome version 76
  (Driver info: chromedriver=76.0.3809.12 (220b19a666554bdcac56dff9ffd44c300842c933-refs/branch-heads/3809@{#83}),platform=Windows NT 10.0.16299 x86_64)
E/launcher - Process exited with error code 199
An unexpected error occurred: undefined

UPDATE: when I ran webdriver-manager clean and node node_modules/protractor/bin/webdriver-manager update --standalone --versions.standalone=3.8.0 it still downloaded chrome 76 here is the output of the second command and ng e2e after the clean
