While setting up protractor, encountered following error while trying to start webdriver manager :

C:\ang\Angular_modules\node_modules>webdriver-manager start

The error does gives us some hint as follows :

[05:55:09] I/start - java -Dwebdriver.chrome.driver=\\usatlkilne01-ctxcifs\ctxprofiles\FolderRedirW10\ajoshi056\AppData\Roaming\npm\node_modules\protractor\node_modules\webdriver-manager\selenium\chromedriver_2.35.exe -Dwebdriver.gecko.driver=\\usatlkilne01-ctxcifs\ctxprofiles\FolderRedirW10\ajoshi056\AppData\Roaming\npm\node_modules\protractor\node_modules\webdriver-manager\selenium\geckodriver-v0.19.1.exe -jar \\usatlkilne01-ctxcifs\ctxprofiles\FolderRedirW10\ajoshi056\AppData\Roaming\npm\node_modules\protractor\node_modules\webdriver-manager\selenium\selenium-server-standalone-3.9.1.jar -port 4444

From the error trace logs it seems :

  • Protractor is considering chromedriver_2.35 as the ChromeDriver binary (e.g. chromedriver_2.35.exe)

  • Protractor is considering geckodriver-v0.19.1 as the GeckoDriver binary (e.g. geckodriver-v0.19.1.exe)

Seems, either the absolute location of the WebDriver binaries are incorrect or you have to change the name of the binaries to the default names as chromedriver.exe and geckodriver.exe

  • Hi Debanjan, Thanks for the help. Can you tell me how to change the names of the binaries or to change the location of webdriver. I am completely new to this – Ash Feb 19 '18 at 13:37

    @Ash Just cross check on this path, whether these binaries exists or not. \\usatlkilne01ctxcifs\ctxprofiles\FolderRedirW10\ajoshi056\AppData\Roaming\npm\node_modules\protractor\node_modules\webdriver-manager\selenium\chromedriver_2.35.exe - – tyaga001 Feb 20 '18 at 10:10

@Ash it seems like the problem is not with your webdriver. And you don't want rename the webdriver. I hope you have set something like the below in your Protractor conf.js.

multiCapabilities: [{ 'browserName': 'firefox' }, { 'browserName': 'chrome' }]

if you change it to capabilities: { 'browserName': 'firefox' } }

or capabilities: { 'browserName': 'chrome' }

And if you really want to run on multiple browsers. Please refer this page.

If this solves kindly try to upvote and check this as correct answer.

If not can you say more about your problem.

One more thing did your ran the 

webdriver-manager update

before doing webdriver-manager start?

seems your selenium-server-standalone-3.9.1.jar is not integral in folder:

\\usatlkilne01-ctxcifs\ctxprofiles\FolderRedirW10\ajoshi056\AppData\Roaming\npm\node_modules\protractor\node_modules\webdriver-manager\selenium\,

please try to unzip it and try to find there is a class org.openqa.grid.selenium.GridLauncherV3 ?

Delete the current selenium-server-standalone-3.9.1.jar, get a new one.
