导入被突出显示，就像包不存在一样 (Symfony 4)

Question

我正在使用 PhpStorm 2018.1 开发 Symfony 4 项目

我经常看到 use 声明突出显示，就好像它们没有与 composer 一起安装一样。

The class belongs to a package which is not directly required in your composer.json. Please add the package into your composer.json.

以下已安装并显示在我的 composer.json 文件中：

stof/doctrine-extensions-bundle
symfony/orm-pack

我是不是遗漏了什么或者这是 PhpStorm 的问题？

Answer 1

你的导入路径是正确的，你的composer.json看起来也不错。

尝试删除 vendor 目录，然后尝试启动 composer install。

尝试在您的 PHPStorm 中安装 Symfony Plugin。

编辑

你的 config/bundles.php 中有下面这行吗？

Doctrine\Bundle\DoctrineBundle\DoctrineBundle::class => ['all' => true],

Answer 2

此消息告诉您的是，突出显示的类仅可用，因为包含它们的包已作为您需要的其他一些包的依赖项安装（在这种情况下，可能是因为 symfony/orm-pack包）。一般来说，依赖这种传递依赖不是我会做的事情。尽管对于 Symfony 包来说这是可以接受的 IMO。

如果您仍然担心此消息，可以通过解压 symfony/orm-pack 来摆脱它（另请参阅 http://fabien.potencier.org/symfony4-unpack-the-packs.html）：

$ composer unpack symfony/orm-pack
