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/wshop/platform> php artisan list
Illuminate/Contracts/Container/BindingResolutionException  : Target class [Modules/ThemeStore/Console/AssetCdn/SyncCommand] does not exist.

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。
