Symfony 编写器更新-无法在中加载包shopware/shopwarehttp://packagist.org:

当我在我的Laravel 5.1上进行composer更新时，会出现以下错误

> Downloading http://packagist.org/p/symfony/polyfill-mbstring$a9a5f6e4a8af44008f50a8c0059a6d1a61b1f692627fb41f0cc1f3e8bbfb7205.json
> Writing /root/.composer/cache/repo/https---packagist.org/provider-symfony$polyfill-mbstring.json into cache



  [RuntimeException]
  Could not load package shopware/shopware in http://packagist.org: [UnexpectedValueException] Could not parse version constraint ~v
  2.0.0-rc1: Invalid version string "~v2.0.0-rc1"




[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"
                },

它处于打开状态，而不是在我的require包中：composer.json 它来自symfony/polyfill mbstring 但为什么在json文件中他们得到了这个

似乎是作曲家本身的问题，我们的全球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

---

我也犯过同样的错误

/composer.phar selfupdate

为我解决问题。

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日打破了此依赖关系：

以下提交在一天后修复了它：

因此，如果您仍遇到此问题，请使用以下命令进行修复：

composer clear-cache
composer update shopware/shopware

谢谢你的回复。但我已经清除缓存并更新了编写器。。仍然存在错误实际上我正在使用centos 6.7我可以确认将我的Satis更新到最新版本解决了我的问题-看起来像是更新版本约束签入Composer。@VaL你能告诉我你的Composer的版本吗？now@EnDiwang
