2、查看 /Modules/ThemeStore/Providers/ThemeStoreServiceProvider.php，提示 未定义的类 ‘ThemeSchemaLoaderInterface’。如图2
3、但是，可以确认 类 ‘ThemeSchemaLoaderInterface’ 是存在的。最后发现 use 的路径有误。删掉掉路径中的 Theme\。IDE 不再提示。如图3
4、执行命令：php artisan list 时报错：Illuminate\Contracts\Container\BindingResolutionException : Target class [Modules\ThemeStore\Console\AssetCdn\SyncCommand] does not exist.
PS E:\wwwroot\object> php artisan list

5、查看 /Modules/ThemeStore/Providers/ThemeStoreServiceProvider.php ，确定 Consoles\AssetCdn\SyncCommand::class 在相应路径下不存在。删除掉相应的调用。如图4
6、再次执行命令：php artisan list 时成功。
