创建数据迁移错误集：
错误描述1：
[ErrorException]
include(F:\phpStudy\WWW\blog\vendor\composer/../../database/migrations/2017_09_06_132637_create_ads_table.php): failed to open stream: No such file or directory
在此错误之前使用php artisan make:migration create_ads_table命令（命令1）执行并创建成功，后来问了与创建数据模型一致就想到用php artisan make:model Ad --migration命令（命令2），所以把已有迁移文件及数据库追踪数据表删除，在执行命令2时产生错误。
解决方法：执行以下3个命令
第一步、 php artisan cache:clear //清楚缓存
F:\phpStudy\WWW\blog>php artisan cache:clear
Cache cleared successfully.
第二步、composer dump-autoload-o
F:\phpStudy\WWW\blog>composer dump-autoload -o

第三步、composer update
F:\phpStudy\WWW\blog>composer update

以上三步执行完，再次执行命令2即可成功创建模型与迁移文件。
