Yii2：主题不工作

Question

我是第一次使用yii2主题。我通过这个 link:Yii2 theme factory

看到了要在 yii2 中实现的主题

根据文档，我下载了主题并安装了。我在放置主题的地方创建了一个 themes 文件夹。

我做了这么多：
在config/web.php文件中

'components' => [
'view' => [
            'theme' => [
                'pathMap' => ['@app/views' => '.@wwwroot/themes/themes'],
                'baseUrl'   => '@www/themes/themes'
            ]
        ],
],

但是，我遇到了这样的错误：

An Error occurred while handling another error:

Answer 1

看起来 @wwwroot 不是有效路径。

如果您使用的是基本应用，请试试这个：

'components' => [
    'view' => [
        'theme' => [
            'pathMap' => ['@app/views' => '@app/themes/mytheme'],
            'baseUrl' => '@web/themePath',
        ],
    ],
],

Answer 2

尝试这样的事情

    'view' => [
        'theme' => [
            'basePath' => '@wwwroot/themes/themes',
            'pathMap' => ['@app/views' => '@wwwroot/themes/themes'],
            'baseUrl'   => '@www/themes/themes'

        ],
    ],

一个常见的错误是像使用 layouts 文件夹而不是 views 文件夹一样使用它。请注意这一点，如果您打算覆盖布局，请在@wwwroot/themes/themes 中创建一个 layouts 文件夹。
