Причину этой ошибки можно найти по адресу Illuminate \ View \ Compilers \ Compiler.php
public function __construct(Filesystem $files, $cachePath)
{
if (! $cachePath) {
throw new InvalidArgumentException('Please provide a valid cache path.');
}
$this->files = $files;
$this->cachePath = $cachePath;
}
Конструктор вызывается BladeCompiler в Illuminate \ View \ ViewServiceProvider
/**
* 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']);
});
}
Итак, отслеживая далее, следующий код:
$this->app['config']['view.compiled']
обычно находится в вашем /config/view.php, если вы используете стандартную структуру laravel.
<?php
return [
/*

'paths' => [
resource_path('views'),
],
/*

*/
'compiled' => realpath(storage_path('framework/views')),
];
realpath (...) возвращает false, если путь не существует. Таким образом, ссылаясь
'Please provide a valid cache path.' error.
Поэтому, чтобы избавиться от этой ошибки, вы можете убедиться, что
storage_path('framework/views')
или
/storage/framework/views
существуют :)
