如何从 Laravel 5.2 升级到 5.4？

我想把Laravel更新到最新的版本5.4。
但是在Laravel迁移指南中没有直接升级的方法，因此我首先尝试将其迁移到laravel 5.3。
我的项目正在5.2 Laravel版本上运行并尝试升级它。
我按照Laravel迁移指南文档的指导更新了composer.json文件。
并在命令行中运行composer update命令。
我遇到了以下错误。
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Loading composer repositories with package information

更新依赖项（包括 require-dev） 您的要求无法解决安装包的集合。

你需要将dompdf包从0.6.1更新到最新版本。 在你的composer.json文件中更新版本为"dompdf/dompdf": "^0.8"。 - Hariharan
没戏，伙计。我也试过了。 - Rahul
仍然出现同样的错误吗？还是其他包依赖版本问题？ - Hariharan
我已更新错误日志信息，请检查。那些错误已经消失了。现在还有一些剩余。 - Rahul
将"laravelcollective/html": "^5.3"更改为v5.4需要laravel框架v5.4。 - Ruchita Sheth

我将Laravel 5.2迁移到了5.6.3，以下是我的步骤：

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

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

其次，更新您的composer.json文件。这是我的默认配置：
{
  "name": "laravel/laravel",
  "description": "The Laravel Framework.",
  "keywords": [
    "framework",
    "laravel"
  ],
  "license": "MIT",
  "type": "project",
  "require": {
    "php": ">=7.1.3",
    "fideloper/proxy": "~4.0",
    "laravel/framework": "5.6.*",
    "laravel/tinker": "~1.0",
    "laravelcollective/html": "^5.5.0"
  },
  "require-dev": {
    "barryvdh/laravel-debugbar": "^3.1",
    "filp/whoops": "~2.0",
    "fzaninotto/faker": "~1.4",
    "mockery/mockery": "~1.0",
    "nunomaduro/collision": "~2.0",
    "phpunit/phpunit": "~7.0",
    "symfony/thanks": "^1.0",
    "doctrine/dbal": "^2.5"
  },
  "autoload": {
    "classmap": [
      "database/seeds",
      "database/factories"
    ],
    "psr-4": {
      "App\\": "app/"
    }
  },
  "autoload-dev": {
    "psr-4": {
      "Tests\\": "tests/"
    }
  },
  "extra": {
    "laravel": {
      "dont-discover": [
      ]
    }
  },
  "scripts": {
    "post-root-package-install": [
      "@php -r \"file_exists('.env') || copy('.env.example', '.env');\""
    ],
    "post-create-project-cmd": [
      "@php artisan key:generate"
    ],
    "post-autoload-dump": [
      "Illuminate\\Foundation\\ComposerScripts::postAutoloadDump",
      "@php artisan package:discover"
    ]
  },
  "config": {
    "preferred-install": "dist",
    "sort-packages": true,
    "optimize-autoloader": true
  },
  "minimum-stability": "dev",
  "prefer-stable": true
}

然后运行 composer update 或者 php composer.phar update

将原始仓库中的 App/Providers/RouteServiceProvider.php 替换为您的版本。

将您的路由从 app/routes/web.php 移动到 routes/web.php（最初，您可能还想复制 Laravel 的原始路由）

用 Laravel 原始仓库中位于 app/Http/Controllers/Auth 文件夹下的 Authentication 控制器替换您的控制器。

注释掉旧的 auth 路由并在 web.php 路由文件中添加 Auth::routes();（更多信息）。

从原始仓库中添加 config/hashing.php。

运行 php artisan config:cache 重新设置缓存。

最后，更新您的数据库结构：php artisan migrate --seed 并运行应用程序：php artisan serve

Laravel 的原始仓库

今天我们是否不需要做更多的工作就可以从5.2迁移到5.6？我正在寻找一种方法来实现这一点。我看到了从5.2升级到5.3的更新，有很多步骤与您的方法相反。谢谢。 - faty fatoumata
你能提供一篇文章的链接吗？ 在我的情况下，我成功地按照上述步骤进行了迁移。 - Leonid Dashko

最终，我最终利用了link的优势，因为这些人集成了一切可能的东西。只有我们方面的小改变，而且当他们升级最新版本的laravel时，他们也会在日志中提到。虽然这是付费的，但一次性投资可以节省时间，值得。

我认为你需要尝试这个：

你必须先更新 LaravelCollective html package。

在你的 composer.json 文件中，将以下内容替换为：

"laravelcollective/html": "5.2.*"

改为：

"laravelcollective/html": "5.4.*"
没戏，伙计，还是出现了同样的错误。但我注意到一件事，错误行数已经减少了。 - Rahul

您需要先更新barryvdh/laravel-dompdf包。

在您的composer.json文件中进行以下更改：

首先更改

"laravel/framework": "5.3.*" 到之前的版本

然后再更改

从

"barryvdh/laravel-dompdf": "^0.6.1",

到

"barryvdh/laravel-dompdf": "^0.8.0",

然后输入composer update命令

然后更改"laravel/framework": "5.3.*"并再次输入命令

`composer update`

命令

首先，将您的“laravel/framework”更改为旧版本，然后执行composer update命令。这样就可以在没有任何错误的情况下首先更新“barryvdh/laravel-dompdf”包，然后再更改“laravel/framework”的版本为“5.3.*”。 - Ruchita Sheth
让我们只是删除"laravelcollective/html": "~5.4"和"barryvdh/laravel-dompdf": "^0.8.0"这两行，然后运行composer update。 - Ruchita Sheth
使用Composer升级到Laravel 5.3后出现问题？请查看升级指南。 - Ruchita Sheth
您可以从EventServiceProvider、RouteServiceProvider和AuthServiceProvider的boot方法中删除参数。 - Ruchita Sheth
让我们在聊天中继续这个讨论。 - Rahul
