"InvalidArgumentException“请在Laravel 8中提供有效的缓存路径

Question

离开一个项目一周，返回(不改变任何东西)之后，我的php artisan就停止工作了。这只是这个特定项目的情况，因为php artisan在其他项目中工作得很好。当我想运行技工命令时，我会得到一个

[InvalidArgumentException] Please provide valid cache path

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

   InvalidArgumentException 

  Please provide a valid cache path.

这个帖子建议在storage\framework dir中创建3个文件夹：

• 会话
• 视图
• 缓存

但我已经有了

​

​

删除这些文件夹并创建新文件夹没有帮助。

我能做什么?

编辑：

删除vendor文件夹并运行composer install将在步骤@php artisan package:discover --ansi生成相同的exception

Answer 1

Laravel需要一个缓存目录来存储已编译的刀片模板。

path在config.view文件中定义如下：

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

正如您可能已经注意到的，Laravel首先查看VIEW_COMPILED_PATH env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，那么它将抛出一个InvalidArgumentException (查看它的框架这里)。

由于某些原因，项目中的compiled路径是错误的。

可以将VIEW_COMPILED_PATH env变量设置为空/空值：

VIEW_COMPILED_PATH=''

OR

VIEW_COMPILED_PATH=

更具体地说，compiled条目返回一个空/空值，跟踪它并签出返回的值。

如果值是正确的，那么其他东西(如中间件)可能已经修改了它。

但是为什么作曲家失败了

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

php artisan package:discover命令将重新生成缓存的包清单，因此它会命中已编译的视图以清除它们。

要解决这个问题，您需要知道为什么config.view.compiled条目返回无效的值。

Answer 2

只需运行这些命令并检查。

php artisan optimize:clear
