在yii2中从bootstrap 4降级到3 [英] Downgrading from bootstrap 4 to 3 in yii2

问题描述

我目前正在使用yii2框架进行项目.我想尝试将Bootstrap 4.0与我的项目一起使用，并在我的 composer.json 文件中添加"yiisoft/yii2-bootstrap":"~2.1.0@dev" 进行了 composer更新.

I was currently working on a project using the yii2 framework. I wanted to try out using bootstrap 4.0 with my project and added "yiisoft/yii2-bootstrap": "~2.1.0@dev" to my composer.json file and ran composer update.

这成功在项目中安装了bootstrap 4.0.0，但是当我开始浏览我的项目以查看受到影响时，我意识到 yii \ bootstrap \ Modal 组件无法正常工作.

This successfully installed bootstrap 4.0.0 in the project but when I started to browse my project to see what was affected I realized that the yii\bootstrap\Modal component was not working.

因此，我想将项目恢复为使用bootstrap 3，并将 composer.json 文件中的条目更改为"yiisoft/yii2-bootstrap":〜2.0.0"并进行了 composer更新，但出现以下错误

Because of this, I want to revert my project back to using bootstrap 3 and changed my entry in the composer.json file to "yiisoft/yii2-bootstrap": "~2.0.0" and did a composer update but got the following error

Your requirements could not be resolved to an installable set of packages.

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting
   see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.

Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.

是我做错了什么，还是有其他方法可以降级到Bootstrap 3?

Is there something that I'm doing wrong or is there another way I can downgrade back to bootstrap 3?

感谢您的任何建议.

推荐答案

您可以映射 assetManager 来加载jquery和bootstrap文件的特定版本，我在上一个项目中也做过同样的事情，我将所有内容保持最新，并仅使用以下配置加载了 bootstrap 3 文件，您可以在 frontend/config/main中的 components 下添加以下内容.php .

You can map the assetManager to load the specific versions for the jquery and bootstrap files I also did the same in my previous project, I kept everything up to date and just used the following configurations to load the bootstrap 3 files, you can add the below under components in frontend/config/main.php.

'assetManager' => [
    'bundles' => [
        'yii\web\JqueryAsset' => [
            'sourcePath' => null , 'js' => [ '//code.jquery.com/jquery-2.2.4.min.js' ] ,
        ] ,
        'yii\bootstrap\BootstrapAsset' => [
            'sourcePath' => null , 'css' => [ '//maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css' ] ,
        ] ,
        'yii\bootstrap\BootstrapPluginAsset' => [
            'sourcePath' => null , 'js' => [ '//maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js' ] ,
        ] ,
    ] ,
] ,
