问题描述
我在PHPStorm中不断收到“类存在多个定义...”的警告，并且在检查时，我看到了这些巨大的PHP-cs-fixer文件（100K +行）中的一堆，并带有注释“此文件是一部分CS CS Fixer”。
我发现出于某种原因，在各种库中的PHPloc下有多个名为composer，PHP-scoper，vendor/library_name/tools/等的其他文件的多个副本。它们都是PHPStorm检测到的巨大的编译文件。
我试图在PHPStorm中一一忽略这些文件，一旦重新索引完成，这些文件就会消失，使我相信它们是IDE生成的文件。但是，IDE不会生成它们并反过来包含它们提示代码。

PHPStorm忽略了文件（在此处添加PHP-cs-fixer和PHPloc以某种方式从vendor目录中删除了所有/多个副本）：
解决方法
这些文件位于您的供应商目录中，因为您必须从源而非发行版安装依赖项。
让我们以 sebastian/code-unit 为例来看看它是如何工作的：
- 该文件显然在存储库中：https://github.com/sebastianbergmann/code-unit/tree/1.0.8/tools
- 但被排除在分发范围之外（您在安装软件包时实际从 GitHub 下载的存档文件）：https://github.com/sebastianbergmann/code-unit/blob/1.0.8/.gitattributes#L6 - 您可以看到它不存在于您从 https://github.com/sebastianbergmann/code-unit/releases/tag/1.0.8 下载的文件中立>
因此，您必须使用 composer install --prefer-source（或 composer update --prefer-source，因为它是具有该选项的另一个命令）安装您的依赖项，并且您想使用 --prefer-dist 或实际上不使用任何这些标记为后者是默认值。您可以在官方文档中找到有关它的更多信息：https://getcomposer.org/doc/03-cli.md#install-i
删除您的供应商目录并在没有 --prefer-source 标志的情况下再次安装依赖项。
AFAIR 当您没有安装 curl 扩展程序时也会出现问题，然后只需添加此扩展程序即可。
