php - 如何从 Laravel 5.2 升级到 5.4？

Question

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

我已经按照 laravel 迁移指南文档的指导更新了 composer.json。
并在命令行上运行命令 composer update。

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.

  Loading composer repositories with package information

更新依赖(包括require-dev) 无法将您的要求解析为一组可安装的软件包。

我需要在 composer.json 中进行哪些额外更改才能使更新生效？

这是composer.json

Answer 1

我从 Laravel 5.2 迁移到 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。
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();
     }
     ...

其次，更新您的 composer.json。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 php composer.phar update

从原始存储库替换您的 App/Providers/RouteServiceProvider.php。

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

从文件夹 app/Http/Controllers/Auth 中的原始 Laravel 存储库替换您的 Controller 以进行身份​​验证

在 web.php 路由文件 (more about this) 中注释掉您的旧身份验证路由并添加 Auth::routes();。

从原始存储库添加 config/hashing.php。

运行 php artisan config:cache 重置缓存。

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