Yii2錯誤：視圖文件不存在

Question

我已經使用了Yii2幾個星期了，並獲得了它的竅門。然而，今天，是有原因的，我不知道，Yii中一直路由我錯誤的頁面，從而導致錯誤，因爲網頁還沒有被發現：

URL: 
http://localhost/web/index.php?r=site/index 

Error: 
Invalid Parameter – yii\base\InvalidParamException 
The view file does not exist: C:\xampp\htdocs\views\site\index.php 

不過，我已經能夠瀏覽我的網站http://localhost/web/index.php?r=paramA/paramB自從我開始使用Yii2以來，我一直沒有編輯配置文件，所以我不知道爲什麼會發生這種情況。

幾個文件，這可能是有用的：

/web/index.php（勉強編輯）：的controllers/SiteController.php

<?php 

require_once __DIR__.'/../util/Tools.php'; 

// comment out the following two lines when deployed to production 
defined('YII_DEBUG') or define('YII_DEBUG', true); 
defined('YII_ENV') or define('YII_ENV', 'dev'); 

require(__DIR__ . '/../vendor/autoload.php'); 
require(__DIR__ . '/../vendor/yiisoft/yii2/Yii.php'); 

$config = require(__DIR__ . '/../config/web.php'); 

(new yii\web\Application($config))->run(); 

部分：

public function actions() 
{ 
    return [ 
     'error' => [ 
      'class' => 'yii\web\ErrorAction', 
     ], 
     ... 
    ]; 
} 

public function actionIndex() 
{ 
    return $this->render('index'); 
} 

此外，在config/web.php我沒有urlManager組件。

爲什麼會發生這種情況，我該怎麼辦？此外，由於我不知道在哪裏搜索，我可能沒有發佈正確的代碼來分析，但我當然可以在必要時添加代碼。

此外，它開始時，我開始投擲一些UserExceptions（要顯示一些無效的發佈請求等）。這即刻顯示一個錯誤，/views/site/error.php不存在。我創建了這個php文件，但之後發生了上述問題。我刪除了/views/site/error.php文件，但問題仍然存在。

我猜它是與URL重寫，但添加urlManager組件/config/web.php（我嘗試後刪除）

後也沒有動靜，在\vendor\yiisoft\yii2\base\View.php有這樣的代碼：

public function render($view, $params = [], $context = null) 
{ 
    $viewFile = $this->findViewFile($view, $context); 
    return $this->renderFile($viewFile, $params, $context); 
} 

而$viewFile返回無法找到的路徑（views\site\index.php）。

此外，在SiteController.php，$this->viewPath是C:\xampp\htdocs\views\site（它不應該..？）

編輯：

你可能已經通過，現在看到的，我的DOCUMENT_ROOT是C:\xampp\htdocs，而我正在使用基本模板

Answer 1

所以，默認情況下，當你在site控制器調用render('index')，Yii的會看的文件夾web/views/site在一個名爲index.php文件。這包含您的site/index視圖文件。它應該在你創建網站時就在那裏，但如果你沒有得到它，那麼它肯定已經在某個階段被刪除了。創建文件並放入視圖代碼，你應該很好。
