我以前从未升级过SilverStripe项目，所以请原谅我，如果我错过任何明显的事情。
我想将我在本地运行的3.0.5 SilverStripe站点升级到最新版本（3.1.6或类似版本）。我更新了我的composer.json文件（位于[project name] /cms/composer.json中的项目中），看起来像这样：
{
"name": "silverstripe/cms",
"type": "silverstripe-module",
"description": "The SilverStripe Content Management System",
"homepage": "http://silverstripe.org",
"license": "BSD-3-Clause",
"keywords": ["silverstripe", "cms"],
"authors": [
{
"name": "SilverStripe",
"homepage": "http://silverstripe.com"
},
{
"name": "The SilverStripe Community",
"homepage": "http://silverstripe.org"
}
],
"require": {
"php": ">=5.3.2",
"composer/installers": "*",
"silverstripe/cms": "3.1.*",
"silverstripe/framework": "3.1.*"
},
"autoload": {
"classmap": ["tests/behat/"]
}
}
我还在终端中提示我更新了作曲家本身。
我去了composer.json文件所在的位置，在终端中运行了composer update并得到了这个错误：
Loading composer repositories with package information

我是否需要具体说明我需要更新到哪个版本的SilverStripe？我没有在项目中看到composer.lock文件，但我确实在web.config中删除了一行调用一行：
<add segment="composer.lock" />
composer.json文件应该位于项目的其他位置（而不是[项目名称] / cms）吗？
更新：在根目录中安装了composer并且位于那里的composure.json文件，在尝试将站点升级到SilverStripe 3.1时仍然会出错：

您不应该编辑cms / composer.json，您应该在项目的根目录下编辑composer.json（如果有一个存在 - 如果以前的开发人员没有＆＃可能没有composer.json 39;用作曲家安装。）
