Question

我是一个旧的Symfony项目，这里是composer.json：

{
"name": "symfony/framework-standard-edition",
"license": "MIT",
"type": "project",
"description": "The \"Symfony Standard Edition\" distribution",
"autoload": {
    "psr-0": {"": "src/"}
},
"require": {
    "php": ">=5.5.9",

    "twig/extensions": "~1.0",
    "symfony/assetic-bundle": "~2.3",
    "symfony/swiftmailer-bundle": "~2.3",
    "symfony/monolog-bundle": "~2.4",
    "sensio/distribution-bundle": "~2.3",
    "sensio/framework-extra-bundle": "~3.0",
    "sensio/generator-bundle": "~2.3",
    "incenteev/composer-parameter-handler": "~2.0",
    "facebook/php-sdk-v4" : "4.0.*",
    "symfony/finder": "^3.1",
    "sonata-project/core-bundle": "^3.1",
    "sonata-project/seo-bundle": "^2.0",
    "sonata-project/admin-bundle": "^3.6"
},
"scripts": {
    "post-install-cmd": [
        "Incenteev\\ParameterHandler\\ScriptHandler::buildParameters",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::buildBootstrap",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::clearCache",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installAssets",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installRequirementsFile"
    ],
    "post-update-cmd": [
        "Incenteev\\ParameterHandler\\ScriptHandler::buildParameters",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::buildBootstrap",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::clearCache",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installAssets",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installRequirementsFile"
    ]
},
"config": {
    "bin-dir": "bin"
},
"extra": {
    "symfony-app-dir": "app",
    "symfony-web-dir": "web",
    "incenteev-parameters": {
        "file": "app/config/parameters.yml"
    },
    "branch-alias": {
        "dev-master": "2.4-dev"
    }
} }

首先我要使用：

php composer.phar self-update

然后我用下面的命令升级：

php composer.phar update

结果如下：

 Search for a package: symfony

Found 15 packages matching symfony

Answer 1

我使用php composer.phar self-update完成，然后php composer.phar update成功更改为symfony 2.8

尝试升级到Symfony的主要版本时安装失败
