I get an error Route [post.destroy] not defined, what should I do?

Question

Laravel

I want to delete a post by a button, but I get an error that such a route does not exist.
show.blade.php:

@extends('layouts.main')

@section('content')
    <div class="post">
        <h3 class="post-title">{{$post->title}}</h3>
        <a href="{{route('post.store')}}">back</a>
        <a href="{{route('post.edit', $post->id)}}">edit</a>
        <form method="POST" action="{{route('post.destroy', $post->id)}}">
            @method('DELETE')
            @csrf
            
            <input type="submit" value="delete">
        </form>
    </div>
    
@endsection

web.php:

Route::get('/', function () {return view('main');})->name('main.index');
Route::get('/posts', '[email protected]')->name('post.index');

Route::get('/posts/create', '[email protected]')->name('post.create');
Route::post('/posts', '[email protected]')->name('post.store');
Route::get('/posts/{post}', '[email protected]')->name('post.show');
Route::get('/posts/{post}/edit', '[email protected]')->name('post.edit');
Route::patch('/posts/{post}', '[email protected]')->name('post.update');
Route::delete('/posts/{post}', '[email protected]')->name('post.destroy');

PostController.php:

public function destroy(Post $post) {
        $post->delete();
        return redirect()->route('post.index');
    }

try

php artisan route:list

if there is no such route there, then there is a problem with caches. php

artisan route:clear

this should help
