Laravel 10安装fruitcake/laravel-cors插件遇依赖冲突问题求助

问题场景 #

• 开发Laravel/React应用时，前端调用接口触发经典CORS错误
• 尝试安装fruitcake/laravel-cors插件，执行命令 composer require fruitcake/laravel-cors --ignore-platform-reqs 后出现依赖冲突：

Your requirements could not be resolved to an installable set of packages.
Problem 1

• Root composer.json requires fruitcake/laravel-cors ^3.0 -> satisfiable by fruitcake/laravel-cors[v3.0.0].
• fruitcake/laravel-cors v3.0.0 requires illuminate[ v6.0.0,..., v6.20.44, v7.0.0,..., v7.30.6, v8.0.0,..., v8.83.27, v9.0.0,..., v9.52.15] but these were not loaded, likely because it conflicts with another require.

解决方案 #

自动匹配兼容版本 #

运行以下命令，让Composer自动检测并安装当前Laravel版本兼容的fruitcake/laravel-cors版本：

composer require fruitcake/laravel-cors:*

指定已知兼容版本 #

若已知当前Laravel版本对应的兼容插件版本（例如Laravel 5.x适配^2.1版本），直接指定版本安装：

composer require fruitcake/laravel-cors:^2.1
