我不明白为什么会发生此错误。

调用 cms 时出错 http://localhost/yii-cms/web/cms

调用未知方法：yii2mod\cms\controllers\CmsController::setInstance()

我尝试使用yii2-cms

我有以下yii2-cms并且效果很好

设置实例错误是由于他们找不到给定的类而发生的，这可能是由于未配置。

按照配置链接 https://github.com/yii2mod/yii2-cms#configuration

1）要使用这个扩展首先你需要配置评论扩展，然后你必须在你的应用程序中配置主配置：

'modules' => [
        'admin' => [
            'controllerMap' => [
                'cms' => 'yii2mod\cms\controllers\CmsController'
                // You can set your template files
                // 'layout' => '@app/modules/backend/views/layouts/main',
                // 'viewPath' => '@app/modules/backend/views/cms/',
            ],
        ],
    ],

You can then access to management section through the following URL:

http://localhost/path/to/index.php?r=admin/cms/index

2) 通过以下代码将新的 Rule 类添加到应用程序配置中的 urlManager 数组中：

 'components' => [
        'urlManager' => [
            'rules' => [
                ['class' => 'yii2mod\cms\components\PageUrlRule'],
            ]
        ],
    ],

3）添加到 SiteController（或通过 urlManager 中的 $route 参数配置）：

/**
 * @return array
 */
public function actions()
{
    return [
        'page' => [
            'class' => 'yii2mod\cms\actions\PageAction',
            // You can set your template files
            'view' => '@app/views/site/page'
        ],
    ];
}
And now you can create your own pages via the admin panel, and access them via the url of each page.

是的，错误可以通过遵循正确的配置步骤来解决。

由于错过配置第二步而发生错误

2) 通过以下代码将新的 Rule 类添加到应用程序配置中的 urlManager 数组中：

'components' => [
        'urlManager' => [
            'rules' => [
                ['class' => 'yii2mod\cms\components\PageUrlRule'],
            ]
        ],
    ],

您需要做的完整配置：

1）要使用这个扩展首先你需要配置评论扩展，然后你必须在你的应用程序中配置主配置：

'modules' => [
        'admin' => [
            'controllerMap' => [
                'cms' => 'yii2mod\cms\controllers\CmsController'
                // You can set your template files
                // 'layout' => '@app/modules/backend/views/layouts/main',
                // 'viewPath' => '@app/modules/backend/views/cms/',
            ],
        ],
    ],

然后，您可以通过以下 URL 访问管理部分：

http://localhost/path/to/index.php?r=admin/cms/index 2) 通过以下代码将新的 Rule 类添加到应用程序配置中的 urlManager 数组中：

'components' => [
        'urlManager' => [
            'rules' => [
                ['class' => 'yii2mod\cms\components\PageUrlRule'],
            ]
        ],
    ],

3）添加到 SiteController（或通过 urlManager 中的 $route 参数配置）：

 /**
     * @return array
     */
    public function actions()
    {
        return [
            'page' => [
                'class' => 'yii2mod\cms\actions\PageAction',
                // You can set your template files
                'view' => '@app/views/site/page'
            ],
        ];
    }

现在您可以通过管理面板创建自己的页面，并通过每个页面的 url 访问它们。

您似乎在您的站点组件中按原样使用 cms 扩展名。

在您的web.php文件中，添加以下内容：

'components' => [ ... 'i18n' => [ 'translations' => [ '*' => [ 'class' => 'yii\i18n\PhpMessageSource', 'basePath' => '@app/messages' 'sourceLanguage' => 'en', ], ], ], ] ..., 'controllerMap': => [ 'cms' => 'yii2mod\cms\controllers\CmsController' ],

注意：您应该排除有关将其配置为管理模块中的组件的路径，因为无论如何您都没有使用它。

如果您在模块中使用它，那么 README 中记录的步骤对您来说就很好。
