如果这发生在服务器上:

sudo mkdir logs framework framework/cache framework/sessions framework/views
sudo chgrp -R www-data storage
sudo chmod -R ug+rwx storage

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

您的存储目录或其中一个子目录可能丢失。存储目录必须包含Laravel安装附带的所有子目录。

当我在存储文件夹内创建框架文件夹及其子文件夹会话，视图和缓存时，我解决了这个问题。

进入你的cmd或终端，然后输入你的项目根路径，然后输入以下命令:

cd storage
mkdir framework
cd framework
mkdir sessions
mkdir views
mkdir cache

再次回到项目根路径并运行composer update

之后，工匠完美地工作。

我这边的问题(在localhost上部署时):有视图文件夹丢失.. 所以 如果你没有框架文件夹，你需要添加文件夹。 但如果已经存在框架文件夹，则确保所有以上文件夹，即 1. 缓存 2. 会话 3.的观点

存在于框架目录中。
