如何在角度量角器中降级 Chrome WebDriver [英] How to downgrade Chrome WebDriver in angular Protractor

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 但我不可能在我的机器上更新 chrome 本身.我使用的是 chrome 74.

我试过了webdriver-manger 更新,webdriver-manager update --versions.chrome 2.46，以及webdriver-manager update --versions.chrome 74.0.3729.6但即使我从 node_modules\protractor\node_modules\webdriver-manager\selenium\ 中删除 chrome 76 文件，但它们总是在我每次运行 ng e2e

量角器.conf.js

exports.config = {allScriptsTimeout: 11000,眼镜: ['./src/**/*.e2e-spec.ts'],能力:{'浏览器名称':'铬'},直接连接:真，baseUrl: 'http://localhost:4200/',框架:茉莉花"，茉莉花节点选项:{显示颜色:真实，默认超时间隔:30000，打印:函数(){}},准备(){require('ts-node').register({项目:需要('path').join(__dirname,'./tsconfig.e2e.json')});jasmine.getEnv().addReporter(new SpecReporter({ spec: { displayStacktrace: true } }));}};

tsconfig.e2e.json

{"extends": "../tsconfig.json",编译器选项":{"outDir": "../out-tsc/app","module": "commonjs","目标": "es5",类型":["茉莉","jasminewd2",节点"]}}

当我尝试运行 ng e2e 时，它会抛出此错误:

E/launcher - session not created: 此版本的 ChromeDriver 仅支持 Chrome 76 版(驱动程序信息:chromedriver=76.0.3809.12 (220b19a666554bdcac56dff9ffd44c300842c933-refs/branch-heads/3809@{#83}),platform=Windows NT 10.0.162699) x86E/launcher - 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 它仍然下载了 chrome 76这是清理后第二个命令和 ng e2e 的输出

解决方案

试试下面的选项

webdriver-manager clean//这将清理现有的 webdrivers节点 node_modules/protractor/bin/webdriver-manager update --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

Try the below option

webdriver-manager clean // This will clean the existing webdrivers

node node_modules/protractor/bin/webdriver-manager update --standalone --versions.standalone=3.8.0
