Magento 2.1.1 无效的块类型异常 - 找不到类答案

【问题标题】：Magento 2.1.1 Invalid block type exception - class not foundMagento 2.1.1 无效的块类型异常 - 找不到类
【发布时间】：2016-09-25 04:53:37
【问题描述】：

尝试加载自定义模块的编辑/创建表单。

在我的生产系统 (linux) 上的 Magento 2.1.1 中，由于在本地主机 xampp / windows 上找不到类而导致无效块类型异常，一切正常。当我想打开表单以创建或编辑自定义实体而网格工作正常时会发生这种情况。

    </config>

存在表单类： app\code\brainworx\medipimsync\Block\Adminhtml\Sync\Edit\Form.php

namespace brainworx\medipimsync\Block\Adminhtml\Sync\Edit;

use Magento\Backend\Block\Template\Context;
use Magento\Framework\Registry;
use Magento\Framework\Data\FormFactory;
use Magento\Store\Model\System\Store;

    }

    /**

        parent::_construct();

        /** @var \Magento\Framework\Data\Form $form */
        $form = $this->_formFactory->create(
                ['data' => ['id' => 'edit_form','action' => $this->getData('action'), 'method' => 'post']]
        );

        $form->setHtmlIdPrefix('sync_');

        $fieldset = $form->addFieldset(
                'base_fieldset',
                ['legend' => __('General Information'), 'class' => 'fieldset-wide']

        $fieldset->addField(

        );

        $fieldset->addField(
                'entity',
                'select',
                [

        $form->setUseContainer(true);
        $this->setForm($form);

        return parent::_prepareForm();
    }
}

编辑类 还有包含表单的编辑类 app\code\brainworx\medipimsync\Block\Adminhtml\Sync\Edit.php

namespace brainworx\medipimsync\Block\Adminhtml\Sync;

class Edit extends \Magento\Backend\Block\Widget\Form\Container
{
    /**
     * Core registry
     *
     * @var \Magento\Framework\Registry
     */
    protected $_coreRegistry = null;

    /**
     * @param \Magento\Backend\Block\Widget\Context $context
     * @param \Magento\Framework\Registry $registry
     * @param array $data
     */
    public function __construct(
            \Magento\Backend\Block\Widget\Context $context,
            \Magento\Framework\Registry $registry,
            array $data = []
    ) {
        $this->_coreRegistry = $registry;
        parent::__construct($context, $data);
    }

    /**
     * Initialize blog post edit block
     *
     * @return void
     */
    protected function _construct()
    {
        $this->_objectId = 'sync_id';
        $this->_blockGroup = 'brainworx_medipimsync';
        $this->_controller = 'adminhtml_sync';

        parent::_construct();

        if ($this->_isAllowedAction('Brainworx_Medipimsync::save')) {
            $this->buttonList->update('save', 'label', __('Creatae new'));
            $this->buttonList->add(
                    'saveandcontinue',
                    [
                            'label' => __('Save and Continue Edit'),
                            'class' => 'save',
                            'data_attribute' => [
                                    'mage-init' => [
                                            'button' => ['event' => 'saveAndContinueEdit', 'target' => '#edit_form'],
                                    ],
                            ]
                    ],
                    -100
            );
        } else {
            $this->buttonList->remove('save');
        }
    }

    /**
     * Retrieve text for header element depending on loaded post
     *
     * @return \Magento\Framework\Phrase
     */
    public function getHeaderText()
    {
        if ($this->_coreRegistry->registry('medipim_sync')->getId()) {
            return __("Edit Sync '%1'", $this->escapeHtml($this->_coreRegistry->registry('medipimsync_sync')->getTitle()));
        } else {
            return __('New Sync');
        }
    }

    /**
     * Check permission for passed action
     *
     * @param string $resourceId
     * @return bool
     */
    protected function _isAllowedAction($resourceId)
    {
        return $this->_authorization->isAllowed($resourceId);
    }

    /**
     * Getter of url for "Save and Continue" button
     * tab_id will be replaced by desired by JS later
     *
     * @return string
     */
    protected function _getSaveAndContinueUrl()
    {
        return $this->getUrl('medipimsync/*/save', ['_current' => true, 'back' => 'edit', 'active_tab' => '']);
    }
}

布局文件 以及加载编辑类的布局文件：view/adminhtml/layout/medipimsync_sync_edit.xml

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <update handle="editor"/>
    <body>
        <referenceContainer name="content">
            <block class="brainworx\medipimsync\Block\Adminhtml\Sync\Edit" name="medipimsync_sync_edit"/>
        </referenceContainer>
    </body>
</page>

【解决方案1】：

经过一天一夜的搜索，已经找到了解决方案。

对于想知道的论文：您应该使目录和模块名称大写。全部更改为 Brainworx\Medipimsync 就成功了！所以 app/code 下的目录都是模块名和命名空间。
