当我尝试安装通知通道laravel-notification-channels/clickatell时，它给了我下面的错误。
我怎样才能清除它？
- Root composer.json requires laravel-notification-channels/clickatell ^0.1.4 -> satisfiable by laravel-notification-channels/clickatell[0.1.4].
- laravel-notification-channels/clickatell 0.1.4 requires illuminate/notifications ~5.5 || ~6.0 || ~7.0 -> found illuminate/notifications[v5.5.0, ..., 5.8.x-dev, v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev] but these were not loaded, likely because it conflicts with another require.
