getting an error on trying to launch Chrome using Protractor - protractor

Question

I'm trying to launch the browser through Protractor. I downloaded webdriver through terminal by giving webdriver-manager update command. This is downloading the latest chromedriver v74, but the chrome browser is v73.
How to explicitly set the WebDriver version?
I'm getting the following error:
[11:09:13] E/driverProvider - Error code: 135
[11:09:13] E/driverProvider - Error message: session not created: This version of ChromeDriver only supports Chrome version 74

Answer 1

is it solved yet? if not then try this.
for my small selenium-webdriver test i did these steps after i researched online and here:
npm install selenium-webdriver
npm install chromedriver
npm install geckodriver and opened file library.js and npm init and ran node library.js (source code below)
Error: (node:14212) UnhandledPromiseRejectionWarning: NoSuchSessionError: invalid session id Some long error related to not same chromedriver version. so i checked the chrome browser version manually in the browser. it was version 73 and my mistake i had downloaded chromedriver version 74.0.
so go to https://chromedriver.storage.googleapis.com/index.html?path=73.0.3683.68/ download according to your OS and download it in ~/Downloads .
then in open terminal in the ~/Downloads folder.
then USER#DESKTOP:~/Downloads$ unzip ~/Downloads/chromedriver_linux64.zip -d ~/Downloads You will get the raw chromedriver file in ~/Downloads folder.
now i moved the ChromeDriver 73.0.3683.68 file to two places - usr/local/bin and usr/bin in my system.
there was already a chromedriver file in usr/local/bin .
to move the file - USER#DESKTOP:~/Downloads$ sudo mv -f ~/Downloads/chromedriver /usr/local/bin/chromedriver and USER#DESKTOP:~/Downloads$ sudo mv -f ~/Downloads/chromedriver /usr/bin/chromedriver you are saying you want to move the file chromedriver from first location to other means replacing any files already in those locations with same name.
Last all i did was. close the vscode and relaunched it. and ran my code node library.js . and it worked it the chrome browser for me.
TOOK AN HOUR FOR ME TO GO THROUGH AROUND 35-40 STACK-OVERFLOW AND RANDOM ONLINE RESOURCES/QUESTION-ANSWERS BUT WAS WORTH IT. :)
SOURCE CODE : LIBRARY.JS
var webdriver = require('selenium-webdriver');
var By = webdriver.By;
var until = webdriver.until;
var driver = new webdriver.Builder().forBrowser('chrome').build();
driver.get('https://www.google.com');

Add this as a script to your package.json file
"scripts": {
"protactorInstall": "cd ./node_modules/protractor && npm i webdriver-manager#latest"}
use
npm run protactorInstall
to execute the script.
