我突然遇到了这个问题。我没有改变作曲家的任何东西，直到上周它运行得很好。现在，当我运行 composer install 我最后得到这个：
Generating autoload files
ocramius/package-versions: Generating version class...
ocramius/package-versions: ...done generating version class
[ErrorException]
Undefined index: vulnerabilities
这使我的部署崩溃，现在我无法在暂存或生产中发布任何内容。
我已经一一删除了软件包，并设法将问题追溯到 symfony/flex。我尝试更新它，但作曲家只是冻结在一个随机步骤上，这对我来说毫无意义。
我已经尝试删除它并运行清理composer require symfony/flex以防我的版本出现问题 - 它安装它然后尝试更新依赖项并永远冻结。
我试过了：
composer clearcache
composer self-update
composer update --no-plugins --noscripts
没有任何效果。它仍然在更新时冻结，并且仍然给我安装错误。我快要绝望了。
这是我的 composer.json 文件：

有谁知道可能是什么原因造成的，或者我还能尝试什么？非常感谢，非常感谢！
