使用Laravel的artisan命令工具执行migrate操作,提示”Class not found”的错误,但是这个migrate类文件是存在的,如遇到这个问题,可执行以下composer dump-autoload,问题得到解决。
一开始报错如下:
[root@iZ94r80gdghZtanteng.me]# php artisan migrate:reset [Symfony\Component\Debug\Exception\FatalThrowableError] Fatalerror: Class 'CreateAttachmentTable' not found
无论执行migrate什么操作都提示类找不到。
执行composer dump-autoload后,再次运行migrate操作,一切正常。
[root@iZ94r80gdghZtanteng.me]# composer dump-autoloadGeneratingautoloadfiles[root@iZ94r80gdghZtanteng.me]# php artisan migrate:resetRolledback: 2016_03_30_104849_create_attachment_tableRolledback: 2016_03_07_094057_create_admins_tableRolledback: 2016_02_22_102354_entrust_setup_tablesRolledback: 2016_02_22_091444_my_ask_anwser_tableRolledback: 2014_10_12_100000_create_password_resets_tableRolledback: 2014_10_12_000000_create_users_table
composer dump-autoload的作用
composer dump-autoload命令的作用是优化自动加载,当把代码部署到生产环境中,或者增加删除了自动加载文件夹里的类文件,需要执行一下自动加载命令,这样自动加载才会起作用。
