Directory Permissions
After installing Laravel, you may need to configure some permissions. Directories within the
storageand thebootstrap/cachedirectories should be writable by your web server or Laravel will not run.
目录权限
安装 Laravel 后，您可能需要配置一些权限。内的目录
storage和bootstrap/cache目录应该是可写的Web服务器或Laravel将无法运行。
