可能是存储文件夹没有应用程序和框架文件夹和必要的权限。在框架文件夹中，它包含缓存、会话、测试和视图。使用下面的命令，这将工作。

Use command line to go to your project root: 
cd {your_project_root_directory}
Now copy past this command as it is: 
cd storage && mkdir app && cd app && mkdir public && cd ../ && mkdir framework && cd framework && mkdir cache && mkdir sessions && mkdir testing && mkdir views && cd ../../ && sudo chmod -R 777 storage/

我希望这能解决你的问题。

试试下面的方法:

在storage/framework下创建以下文件夹:

会话 的观点 缓存

现在应该可以了

首先清除缓存

php artisan cache:clear
php artisan config:clear
php artisan view:clear

如果它不起作用，请确保以下所有文件夹都可用

logs
framework
framework/cache 
framework/sessions 
framework/views

如果这些建议都不起作用，请验证配置文件config/view.php是否存在。如果没有，您可以为您正在使用的Laravel获取该文件的副本，并将其复制到项目配置文件夹。

这个错误的原因可以从Illuminate\View\Compilers\Compiler.php中找到

public function __construct(Filesystem $files, $cachePath)
{
    if (! $cachePath) {
        throw new InvalidArgumentException('Please provide a valid cache path.');
    }

    $this->files = $files;
    $this->cachePath = $cachePath;
}

该构造函数由BladeCompiler在Illuminate\View\ViewServiceProvider中调用

/**
 * Register the Blade engine implementation.
 *
 * @param  \Illuminate\View\Engines\EngineResolver  $resolver
 * @return void
 */
public function registerBladeEngine($resolver)
{
    // The Compiler engine requires an instance of the CompilerInterface, which in
    // this case will be the Blade compiler, so we'll first create the compiler
    // instance to pass into the engine so it can compile the views properly.
    $this->app->singleton('blade.compiler', function () {
        return new BladeCompiler(
            $this->app['files'], $this->app['config']['view.compiled']
        );
    });

    $resolver->register('blade', function () {
        return new CompilerEngine($this->app['blade.compiler']);
    });
}

因此，进一步追溯，下面的代码:

$this->app['config']['view.compiled']

通常位于你的/config/view.php，如果你使用标准laravel结构。

<?php
return [
    /*
    |--------------------------------------------------------------------------
    | View Storage Paths
    |--------------------------------------------------------------------------
    |
    | Most templating systems load templates from disk. Here you may specify
    | an array of paths that should be checked for your views. Of course
    | the usual Laravel view path has already been registered for you.
    |
    */
    'paths' => [
        resource_path('views'),
    ],
    /*
    |--------------------------------------------------------------------------
    | Compiled View Path
    |--------------------------------------------------------------------------
    |
    | This option determines where all the compiled Blade templates will be
    | stored for your application. Typically, this is within the storage
    | directory. However, as usual, you are free to change this value.
    |
    */
    'compiled' => realpath(storage_path('framework/views')),
];

如果路径不存在，Realpath(…)返回false。因此,调用

'Please provide a valid cache path.' error.

因此，要摆脱这个错误，你能做的就是确保

storage_path('framework/views')

or

/storage/framework/views

存在:)

步骤1:PHP工匠存储:链接

步骤2:在存储文件夹中创建这些文件夹

确保存储目录中有以下文件夹:

日志 框架 框架/缓存 框架/会议 框架/观点 这对我很有效

这对我也有用

我的2美分

删除存储中的所有内容，然后执行以下操作:

> cd storage/
> mkdir -p framework/{sessions,views,cache}
> chmod -R 755 framework

// This last line depends on your user group settings so 
// it may not be applicable to you.
> chown -R www-data:www-data framework

为我工作过=)
