【问题描述】：

我尝试运行“php composer.phar update”，但出现此错误：

Key extra is a duplicate in ./composer.json at line 94
ComposerHookHandler::onPreUpdate
Deprecation Notice: The Composer\Package\LinkConstraint\VersionConstraint class is deprecated, use Composer\Semver\Constraint\Constraint instead. in phar:///home/budrysl2/domains/westeros.com.pl/public_html/composer.phar/src/Composer/Package/LinkConstraint/VersionConstraint.php:17

我在 westeros.com.pl 上的 MediaWiki 页面上使用它

有人可以帮我吗？

【问题讨论】：

请发布您的 composer.json 文件。问题出在它里面
你可以在这里找到我的 comoser.json 文件：westeros.com.pl/composer.txt
您的 json 文件中有错误 - 您有重复的额外部分。 Composer 无法完全解码您的配置，因此失败并出现错误。
那么我应该合并那些额外的部分吗？
我认为是的。这必须解决您的问题

标签： php json symfony composer-php

【解决方案1】：

除了重复的"merge-plugin" 键之外，您的composer.json 是正确的，并且可以在我的设置中正常安装：

Generating optimized autoload files
Key merge-plugin is a duplicate in ./composer.json at line 92
Class ComposerHookHandler is not autoloadable, can not call pre-update-cmd script
Loading composer repositories with package information
Updating dependencies (including require-dev)
Nothing to install or update

也许之前的某个包依赖项有问题？

【讨论】：

我之前不确定依赖项的问题？如何检查？如何更新它们？
如果您现在在文件上运行composer update，它应该可以正常工作
