Lumen 5.7.5 打破了绑定解析

Question

更新:

流明版本：5.7.5

PHP版本：7.2

我刚刚完成了从 5.5 到 5.6 到 5.7 的升级，直到 5.7.4 一切都按预期工作，只要我引入 5.7.5。 PHP Artisan 给我

"Target [Illuminate\Contracts\Debug\ExceptionHandler] is not instantiable."

示例：

PHP artisan

在 Container.php 行 945:

目标 [Illuminate\Contracts\Debug\ExceptionHandler] 不可实例化。重现步骤：从 5.5 升级到 5.6 再到 5.7，最后从 5.7.4 升级到 5.7.5。

我正在检查所有代码更改以及可能导致此问题的原因。

也许你们有想法？

这是堆栈跟踪：

#8 {main}

因此我在 Github 上创建了一个问题：

Answer 1

在 Lumen V5.7.6 中发布了一个修复程序。

它基本上归结为引导过程中的路径覆盖。

Lumen中的application.php一直在使用命令static:class而不是class路径。

这已更改为 self:class 以反映正确的当前路径。

This is the commit that broke it

This is the commit that fixes it

在某些情况下，您可能希望覆盖基本应用程序路径，因此您可以在覆盖基本应用程序路径时添加别名，例如在 app.php 中引导应用程序时。

例如

$app->alias(overwrite\path\Application::class, \Laravel\Lumen\Application::class);

希望这对某人有所帮助，尽管新提交应该修复任何手动覆盖以反映正确的 class 路径。
