Unable to use Protractor webdriver-manager

Question

I am trying to start protractor on my local Windows development machine. In an attempt to do so, I am trying to start it from the command-line using the following command:

Answer 1

Try installing it globally as an Administrator:

npm install -g webdriver-manager

Answer 2

Install protractor globally.

npm install protractor -g

This will install protractor and webdriver-manager. Then run from the command line: webdriver-manager update Check for more info on: http://angular.github.io/protractor/#/tutorial

Answer 3

use grunt-protractor-webdriver, you also need protractor in your package.json if you don`t installed it as global (-g)

add this to your package.json under "devDependencies":

    "protractor": "^2.1.0",
    "grunt-protractor-webdriver": "^0.2.0",

also look at grunt-protractor-runner it can start protractor from a grunt process without starting the selenium server ( webdriver-manager start )

to start the selenium server with grunt-protractor-webdriver add this to your Gruntfile

    protractor_webdriver: {
        options: {
          keepAlive: true
        }
    }

and add it to a grunt-task

    grunt.registerTask('start-selenium-server', ['protractor_webdriver']);

If you are a Windows user, this could help you:

1. Add C:\Users\%username%\AppData\Roaming\npm to the PATH variable.

2. Close cmd/powershell and open it again.

3. Try webdriver-manager

webdriver-manager is actually a NodeJS script. Run it using
