Php Laravel更新至5.8，更新依赖项

我目前已将laravel从5.2更新到5.8。在整个过程中，我让它工作并显示站点，但我没有添加所有5.8依赖项，就像我从5.8开始项目一样。所以我从头开始创建了一个laravel项目，看看会包含什么，然后我开始慢慢地移动。目前，我正在尝试使composer.json与新的laravel 5.8项目几乎相同。这就是我们所做的--

我改成了--

在尝试运行此更新脚本之后，我遇到了如下错误

任何建议

我都明白了，默认情况下，api使用一个包含函数（）的路由。因为闭包不能序列化，所以当您有使用闭包的路由时，您不能缓存路由

修正--

注释掉\routes\api.php中的测试路由
