controllersdependency-injectionerrormagento2php-5.4

I working on creating custom module in magento 2, but it's not working. Could you please suggest me where i went wrong?.

My module code:

app/etc/config.php:

'modules' => 
  array (
    'Ramesh_Sample' => 1,
         ),

app/code/Ramesh/Sample/etc/module.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd">
    <module name="Ramesh_Sample" schema_version="2.0.0">
    </module>
</config>

app/code/Ramesh/Sample/etc/frontend/routes.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="../../../../../../lib/internal/Magento/Framework/App/etc/routes.xsd">
    <router id="standard">
        <route id="sample" frontName="sample">
            <module name="Ramesh_Sample" />
        </route>
    </router>
</config>

app/code/Ramesh/Sample/Controller/Index/Index.php

<?php
namespace Ramesh\Sample\Controller\Index;

use Magento\Framework\App\Action\Context;
//use \Magento\Framework\View\Result\PageFactory;

class Index extends \Magento\Framework\App\Action\Action
{
    private $_resultPageFactory;

    public function __construct(
        Context $context,
        \Magento\Framework\View\Result\PageFactory $resultPageFactory
    )
    {
        parent::__construct($context);
        $this->_resultPageFactory = $resultPageFactory;
    }

    public function execute()
    {
        $result = $this->_resultPageFactory->create();
        return $result;
    }
}

app/code/Ramesh/Sample/Block/Sample.php

namespace Magento\Sample\Block;
class Sample extends \Magento\Framework\View\Element\Template
{
}

app/code/Ramesh/Sample/views/frontend/layout/sample_index_index.xml

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd">
    <head>
        <title>Hello World</title>
    </head>
    <body>
        <referenceContainer name="content">
            <block class="Sample\Ramesh\Block\Sample" name="sample"      template="sample.phtml">
            </block>
        </referenceContainer>
    </body>
</page>

app/code/Ramesh/Sample/view/frontend/templates/sample.phtml

<?php echo 'Hi I am Magento 2'; ?>

But I got the following error:

a:4:{i:0;s:380:"Recoverable Error: Argument 2 passed to Ramesh\Sample\Controller\Index\Index::__construct() must be an instance of Magento\Framework\View\Result\PageFactory, none given, called in var/generation/Ramesh/Sample/Controller/Index/Index/Interceptor.php on line 14 and defined in app/code/Ramesh/Sample/Controller/Index/Index.php on line 14";i:1;s:6109:"#0 app/code/Ramesh/Sample/Controller/Index/Index.php(14): Magento\Framework\App\ErrorHandler->handler(4096, 'Argument 2 pass…', '/var/www/html/m…', 14, Array)

Best Answer

try to delete your module from the var/generation/vendor-name/your-module and try to refresh the page and check if it's working.
