Symfony\Component\Debug\Exception\FatalThrowableError ：语法错误，意外的“公共”（T_PUBLIC）

Question

您好，我遇到了问题PHP artisan migrate does not migrate all tables 遵循了该程序，但我遇到了另一个错误。

    λ php artisan migrate

       Symfony\Component\Debug\Exception\FatalThrowableError  : syntax error, unexpected 'public' (T_PUBLIC), expecting end of file

      at C:\laragon\www\blog\app\Providers\AppServiceProvider.php:34
        30| }
        31|
        32| use Illuminate\Support\Facades\Schema;
        33|
      > 34| public function boot()
        35| {
        36|     Schema::defaultStringLength(191);
        37| }
        38|

      Exception trace:

      1   Composer\Autoload\includeFile("C:\laragon\www\blog\vendor\composer/../../app/Providers/AppServiceProvider.php")
          C:\laragon\www\blog\vendor\composer\ClassLoader.php:322

      Please use the argument -v to see more details.

AppServiceProvider.php 文件已更改，我什至尝试将新类放在顶部。并且错误是相同的，除非它在不同的行上检测到。

    <?php

    namespace App\Providers;





    use Illuminate\Support\ServiceProvider;

    class AppServiceProvider extends ServiceProvider
    {
        /**
         * Register any application services.
         *
         * @return void
         */
        public function register()
        {
            //
        }

        /**
         * Bootstrap any application services.
         *
         * @return void
         */
        public function boot()
        {
            //


        }
    }

    use Illuminate\Support\Facades\Schema;

    public function boot()
    {
        Schema::defaultStringLength(191);
    }

您的app/Providers/AppServiceProvider.php 应该与此类似

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider {

    public function boot(){
        \Schema::defaultStringLength(191);
    }

    public function register()
    {
        //
    }

}
