【问题描述】：
我有一个旧的 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",

},
"scripts": {
"post-install-cmd": [
"Incenteev\\ParameterHandler\\ScriptHandler::buildParameters",

],

"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"
},

}
} }
首先我会使用：
php composer.phar self-update
然后我使用以下命令进行升级：
php composer.phar update
结果如下：

【问题讨论】：
-
开始一个新的 Symfony 项目以获得一个工作的 composer.json 然后使用 composer require 添加额外的包，比如 facebook sdk。用新的 composer.json 替换旧的 composer.json，重新安装，然后开始工作，尽管您将面临许多问题。除非你对 Symfony 有深入的了解，否则你最好分步升级：2.2 => 2.3 => 2.7 => 2.8 => 3.1 随着你的进展清除所有弃用通知。或者将你的旧应用一点一点复制到新应用中。
-
谢谢，但这些对我来说很难，因为我是新手，但我想了解更多，有没有办法解决我遇到的所有错误？
-
我想你可以雇人。否则，您基本上就不得不学习如何使用 Symfony 框架进行开发。
-
不，我说我只是想升级这些项目。
-
我想支持@Cerad 所说的话。 2.2 和 3.x 之间有很多变化，但你不会找到灵丹妙药。
