php - 试图从命名空间 "WebpackEncoreBundle"加载类 "Symfony\WebpackEncoreBundle"。您是否忘记了另一个命名空间的 "use"语句？

Question

我有一个奇怪的问题。我使用 Symfony Flex 并处理现有项目。我尝试使用以下命令安装 webpack-encore-bundle:

composer require symfony/webpack-encore-bundle

然后我明白了:

./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Restricting packages listed in "symfony/symfony" to "4.2.*"
Package operations: 1 install, 0 updates, 0 removals

Package symfony/webpack-encore-pack is abandoned, you should avoid using it. Use symfony/webpack-encore-bundle instead.

Executing script assets:install --symlink --relative public [OK]

Some files may have been created or updated to configure your new packages.
Please review, edit and commit them: these files are yours.

然后我运行:

yarn install

我明白了:

    yarn install v1.16.0
warning package-lock.json found. Your project contains lock files generated by tools other than Yarn. It is advised not to mix package managers in order to avoid resolution inconsistencies caused by unsynchronized lock files. To clear this warning, remove package-lock.json.

一切似乎都很好。现在我刷新项目并得到这个:

ClassNotFoundException

Attempted to load class "WebpackEncoreBundle" from namespace "Symfony\WebpackEncoreBundle".
Did you forget a "use" statement for another namespace?

所以这是我在 bundles.php 中的内容:

Symfony\WebpackEncoreBundle\WebpackEncoreBundle::class => ['all' => true],

在 composer.json 我有:

"autoload": {
    "psr-4": {
        "App\\": "src/"
    }
},

我跑:

yarn encore dev

编译成功了，但是我也有同样的错误。

我也试过这个命令:

composer remove symfony/webpack-encore-bundle

那我再试试

composer require symfony/webpack-encore-bundle

然后我们得到了同样的错误，这个循环永远不会结束。

我有这个错误，我只是通过安装 webpack-encore-bundle 修复了它:

composer require symfony/webpack-encore-bundle

在我的例子中，我必须在 webpack-encore-bundle 之前安装 doctrine-orm-admin-bundle:

composer require sonata-project/doctrine-orm-admin-bundle
