事情的经过是这样的：
一、我闲着没事更新了一下依赖
1 | composer update |
批量更新，控制台大概是这样的，更新了一大堆，这下尴尬了
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 | bash-4.4# composer update Do not run Composer as root/super user!

二、然后启动时，报错了
启动命令
1 | php bin/hyperf.php start |
报错如下
1 2 3 4 5 6 7 | PHP Fatal error: Declaration of Hyperf\Framework\SymfonyEventDispatcher::dispatch($event) must be compatible with Symfony\Contracts\EventDispatcher\EventDispatcherInterface::dispatch(object $event, ?string $eventName = NULL): object in /hyperf-skeleton/vendor/hyperf/framework/src/SymfonyEventDispatcher.php on line 23 Fatal error: Declaration of Hyperf\Framework\SymfonyEventDispatcher::dispatch($event) must be compatible with Symfony\Contracts\EventDispatcher\EventDispatcherInterface::dispatch(object $event, ?string $eventName = NULL): object in /hyperf-skeleton/vendor/hyperf/framework/src/SymfonyEventDispatcher.php on line 23 |
好像是什么奇怪的地方冲突了
三、解决办法
经一位前辈指点，说这个问题他也遇到过，官网上有解决办法。
hyperf官网 常见问题
截图如下
命令如下
1 2 3 | rm -rf vendor rm -rf composer.lock composer require "symfony/event-dispatcher:^4.3" |
按顺序执行，冲突解决了，启动 php bin/hyperf.php start 成功，又能愉快的玩耍了。
