Paste the script given below on PowerShell Window and click enter button.

Check that your SharePoint site feature will be activated successfully.

Syntax Explanation

Add-SPGroup -webUrl "http://gowtham.sharepoint.com"

-groupName "SharePointOwner"

-description "SPOwners"

-ownerName "spdev\gowtham"

-defaultMemberName "spdev\gowtham" `\

-membership "spdev\gowtham"

function Add-SPGroup {


[CmdletBinding()]
Param(
    [Parameter(Mandatory=$true)][string]$webUrl,
    [Parameter(Mandatory=$true)][string]$groupName,
    [Parameter(Mandatory=$true)][string]$description,
    [Parameter(Mandatory=$true)][string]$ownerName,
    [Parameter(Mandatory=$true)][string]$defaultMemberName,
    [Parameter(Mandatory=$true)][string]$membership
)
try {

    Write-Host "Checking  Group already exists"
    $web = Get-SPWeb $webUrl;
    $spGroup = $web.SiteGroups[$groupName];

    if ($spGroup -ne $null) {
        Write-Warning "Group $groupName already exists in this site!";
        return $spGroup;
    }

    $owner = $web.EnsureUser($ownerName);
    $member = $web.EnsureUser($defaultMemberName);

     Write-Host "Creating Group"
    $web.SiteGroups.Add($groupName, $owner, $member, $description);
    $spGroup = $web.SiteGroups[$groupName];

   Write-Host "Adding users to Group"
    $usersToAdd = $membership.split(",");
    foreach($user in $usersToAdd) {
        $ensuredUser = $web.EnsureUser($user.trim());
        $spGroup.AddUser($ensuredUser);
    }

    $web.RoleAssignments.Add($spGroup);
    $web.Dispose();
    return $spGroup;
}
catch {

    Write-Error $Error[0];
} }
