【问题描述】：

当我在我的 Laravel 5.1 上进行作曲家更新时，会出现此错误

  [RuntimeException]
  Could not load package shopware/shopware in http://packagist.org: [UnexpectedValueException] Could not parse version constraint ~v

[UnexpectedValueException]
  Could not parse version constraint ~v2.0.0-rc1: Invalid version string "~v2.0.0-rc1"

当我在缓存文件夹中跟踪它时

"require-dev": {
                    "phpunit\/phpunit": "~4.5",
                    "phpunit\/dbunit": "~1.3",
                    "behat\/mink": "~1.7",
                    "behat\/mink-extension": "~2.1",
                    "behat\/mink-goutte-driver": "~1.2",
                    "behat\/mink-selenium2-driver": "~1.3",
                    "symfony\/dom-crawler": "~2.8",
                    "behat\/behat": "~3.1",
                    "sensiolabs\/behat-page-object-extension": "~v2.0.0-rc1"
                },

它不在我的要求包中：composer.json 它来自 symfony/polyfill-mbstring 但是为什么在 json 文件中他们得到了这个？

标签： symfony laravel composer-php updates

【解决方案1】：

似乎是作曲家本身的问题，我们的全局作曲家也有同样的问题。您需要清除 /root/.composer/ 中的缓存和供应商映射并更新 composer 本身：

cd /root
curl -sS https://getcomposer.org/installer | sudo php --
php composer.phar global update
rm composer.phar

【讨论】：

感谢您的回复。但我已经清除缓存并更新作曲家..实际上我使用centos 6.7时仍然出现错误

【解决方案2】：

我遇到了完全相同的错误

./composer.phar selfupdate为我解决问题。

【讨论】：

我可以确认将我的 Satis 更新到最新版本可以解决我的问题 - 似乎是 Composer 中的更新版本约束检查。
@VaL 你能告诉我你的作曲家是什么版本的吗？现在
@EnDiwang Composer version 1.0-dev (e8b1a5f35772e39ca21ab855a278bd84a0a534b2) 2016-03-29 07:53:57

【解决方案3】：

这不是 Composer 中的问题，而是 Shopware 上游软件包的问题。

以下提交在 3 月 29 日打破了这种依赖关系： https://github.com/shopware/shopware/commit/e44e4a7d788675489aadbd664c50a7cfc47e0f05

以下提交在一天后修复了它： https://github.com/shopware/shopware/commit/0cec1d69e972150b3d1fa71b82e621031ff341e3

因此，如果您仍然遇到此问题，请使用以下命令进行修复：

composer clear-cache
composer update shopware/shopware
