如何从 laravel 5.2 升级到 5.4？

How to Upgrade from laravel 5.2 to 5.4?

提问by Rahul

I want to update Laravel to the latest version 5.4.
But direct migration is not given in laravel migration guide, so first I am trying to migrate it to laravel 5.3.
My project is working on a 5.2 laravel version and trying to upgrade it.

我想将 Laravel 更新到最新版本 5.4。
但是在laravel 迁移指南中没有给出直接迁移，所以首先我试图将它迁移到 laravel 5.3。
我的项目正在开发 5.2 laravel 版本并尝试升级它。

I have updated composer.jsonas guided into the documentation of laravel migration guide.
And run command composer updateon the command line.

我已经composer.json按照 laravel 迁移指南的文档中的指导进行了更新。
并composer update在命令行上运行命令。

I am getting the following error.

我收到以下错误。

Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

What extra changes do I need to make in composer.json to make the update work?

In the end I end up using advantage of linkas these people integrated everything possible. Just minor changes from our side, that too they will mention in the log when they upgrade latest version of laravel. Its paid thing, but one time investment to save time worth it.

最后我最终使用了链接的优势，因为这些人整合了一切可能。只是我们这边的一些小改动，当他们升级最新版本的 laravel 时，他们也会在日志中提到这一点。它是付费的，但是为了节省时间而进行的一次性投资是值得的。

I migrated from Laravel 5.2 to 5.6.3 Here are my steps:

我从 Laravel 5.2 迁移到 5.6.3 以下是我的步骤：

Firstly, you need to update providers app/Providers/{EventServiceProvider, RouteServiceProvider}.php.
Their boot() methods shouldn't take arguments:

首先，您需要更新提供者app/Providers/{EventServiceProvider, RouteServiceProvider}.php。
他们的 boot() 方法不应该带参数：

     ...
-    public function boot(DispatcherContract $events)
+    public function boot()
     {
-        parent::boot($events);
+        parent::boot();
     }
     ...

Secondly, update your composer.json. Here is my default configuration:

其次，更新你的 composer.json。这是我的默认配置：

    ],
    "psr-4": {

    }
  },
  "autoload-dev": {

    "preferred-install": "dist",
    "sort-packages": true,
    "optimize-autoloader": true
