尝试使用Composer安装Laravel 5时出现PHP致命错误

Question

I'm trying to run composer to install Laravel 5.0.14, and am also trying to test this code out in Jenkins using the Jenkins php-template.

Whenever I run composer update, I get the following error:

Error Output: PHP Fatal error: Call to undefined method 
Illuminate\Foundation\Application::redirectIfTrailingSlash() 
  in /var/lib/jenkins/jobs/Demo/workspace/bootstrap/start.php on line 16

If I remove the offending line in start.php, I obtain the following error when attempting to run composer update:

Error Output: PHP Catchable fatal error: 
  Argument 1 passed to Illuminate\Foundation\Application::detectEnvironment() 
   must be an instance of Closure, array diven, called in 
   /var/lib/jenkins/jobs/Demo/workspace/bootstrap/start.php on line 32 
     and defined in 
   /var/lib/jenkins/jobs/Demo/workspace/vendor/laravel/framework/src/Illuminate
   /Foundation/Application.php
 on line 402

This is my composer.json file:

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "require": {

        "pear/pear_exception": "1.0.0",
        "phing/phing": "2.6.1"
    },
    "autoload": {
        "classmap": [
            "app/commands",
            "app/controllers",
            "app/models",
            "app/database/migrations",
            "app/database/seeds",
            "app/tests/TestCase.php"
        ]
    },
    "scripts": {
        "post-install-cmd": [
            "php artisan optimize"
        ],
        "pre-update-cmd": [
            "php artisan clear-compiled"
        ],
        "post-update-cmd": [
            "php artisan optimize"
        ],
        "post-create-project-cmd": [
            "php artisan key:generate"
        ]
    },
    "config": {
        "preferred-install": "dist"
    },
    "minimum-stability": "dev"
}

I can run composer update --no-scripts.

I've searched for any composer.php files with sudo find . -print | grep -i 'compiled.php'. The only one I have is

./vendor/symfony/dependency-injection/Tests/Fixtures/php/services9_compiled.php

which does not correspond with the compiled.php file several other people have suggested deleting for other people who have had this problem.

I think you are using a Laravel 4 composer.json. One of the big changes from Laravel 4 to Laravel 5 is the usage of namespaces. Also a lot of paths have been modified, so just installing Laravel 5 over an existing Laravel 4 is not possible. Better to install a fresh Laravel 5 and follow this guide: http://laravel.com/docs/master/upgrade#upgrade-5.0

For reference here is my composer.json (notice the psr-4 in the autoload section)

{
"name": "laravel/laravel",
"description": "The Laravel Framework.",
"keywords": ["framework", "laravel"],
"license": "MIT",
"type": "project",
"require": {
    "laravel/framework": "5.0.*",
},
"require-dev": {
    "phpunit/phpunit": "~4.0",
    "phpspec/phpspec": "~2.1"
},
"autoload": {
    "classmap": [
        "database"
    ],
    "psr-4": {
        "App\\": "app/"
    }
},
"autoload-dev": {
    "classmap": [
        "tests/TestCase.php"
    ]
},
"scripts": {
    "post-install-cmd": [
        "php artisan clear-compiled",
        "php artisan optimize"
    ],
    "post-update-cmd": [
        "php artisan clear-compiled",
        "php artisan optimize"
    ],
    "post-create-project-cmd": [
        "php -r \"copy('.env.example', '.env');\"",
        "php artisan key:generate"
    ]
},
"config": {
    "preferred-install": "dist"
}
}
