为什么我用PhpStorm 打开laravel 的 项目 提示不一样

这是我安装的6.X 版本的 敲Route 少了箭头的提示

这是最新的版的

有人知道什么问题吗？

而且 6.X 版本
执行 php composer require barryvdh/laravel-ide-helper 报错

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

  Problem 1
    - barryvdh/laravel-ide-helper[dev-master, v2.9.0] require illuminate/console ^8 -> found illuminate/console[v8.0.0, ..., 8.x-dev] but these were not loaded, likely because it conflicts with another require.
    - barryvdh/laravel-ide-helper 2.9.x-dev is an alias of barryvdh/laravel-ide-helper dev-master and thus requires it to be installed too.
    - Root composer.json requires barryvdh/laravel-ide-helper ^2.9 -> satisfiable by barryvdh/laravel-ide-helper[v2.9.0, 2.9.x-dev (alias of dev-master)].


Installation failed, reverting ./composer.json and ./composer.lock to their original content.

有人遇到个这样的问题吗？如何解决
