“InvalidArgumentException”请在 Laravel 8 中提供有效的缓存路径答案

【问题标题】："InvalidArgumentException" Please provide valid cache path in Laravel 8“InvalidArgumentException”请在 Laravel 8 中提供有效的缓存路径

【问题描述】：

在离开一个项目一周并返回（没有更改任何内容）后，我的 php artisan 停止工作。这只是这个特定项目的情况，因为php artisan 在其他项目中工作正常。当我想运行工匠命令时，我得到了一个

[InvalidArgumentException] Please provide valid cache path:

PS C:\Users\Artur\PhpstormProjects\stuttard.de> php artisan serve

   InvalidArgumentException 

  Please provide a valid cache path.

This thread 建议在storage\framework 目录中创建3个文件夹：

会话
观看次数
缓存

但我已经有了这些：

删除这些文件夹并重新创建它们没有帮助。

我能做什么？

编辑：

删除vendor 文件夹并运行composer install 在步骤@php artisan package:discover --ansi 处产生相同的exception：

【问题讨论】：

你试过更新作曲家吗？
@ArjanShrestha 是的，结果完全相同。
也许尝试删除供应商文件夹然后作曲家安装
@ArjanShrestha 我运行了命令，但是当composer 进程（？）php artisan 时，它以相同的exception 结束。请参阅编辑部分。
检查你的laravel版本是否支持你当前的php版本

【解决方案1】：

Laravel 需要有一个缓存目录来存储编译好的刀片模板。

path 在config.view 文件中定义如下：

    'compiled' => env(
        'VIEW_COMPILED_PATH',
        realpath(storage_path('framework/views'))
    ),

您可能已经注意到，Laravel 首先查看 VIEW_COMPILED_PATH 环境变量（如果有的话），如果它不存在，则返回到 storage/framework/views。

如果 Laravel（出于任何原因）无法获得正确的路径，那么它将抛出 InvalidArgumentException（查看框架 here）。

由于某种原因，您的项目中的 compiled 路径错误。

可能是 VIEW_COMPILED_PATH 环境变量设置为空/null 值：

VIEW_COMPILED_PATH=''

OR

VIEW_COMPILED_PATH=

更具体地说，compiled 条目返回一个空/null 值，跟踪它并检查返回值。

如果值是正确的，那么其他东西（例如中间件）可能已经修改了它。

为什么作曲家失败了？

当你运行 composer install/update 时，laravel 使用 composer script post-autoload-dump 来运行 php artisan package:discover 命令。

php artisan package:discover 命令将重建缓存的包清单，因此它会点击已编译的视图以清除它们。

要解决此问题，您需要知道为什么config.view.compiled 条目返回无效值。

【讨论】：

您好，感谢您的详尽解释。我不知道这是怎么发生的，因为我没有手动触摸env variable。我想我会重新创建项目的基础并复制组件。
IMO，你应该追查，不要建立新的基础；软件开发是一个学习过程，花点时间调试一下，看看为什么会这样。

【解决方案2】：

只需运行这些命令并检查。

php artisan optimize:clear
