Question

在第一个 composer install 命令上（就在克隆项目之后），我收到了这个错误：

Generating autoload files
  [ErrorException]
  Undefined index: vulnerabilities

更详细一些，我明白了：

Generating autoload files
composer/package-versions-deprecated: Generating version class...
composer/package-versions-deprecated: ...done generating version class

似乎是 symfony/flex 的问题。因为当我检查文件下载时：https://flex.symfony.com/p/symfony,polyfill-php80,iv1.22.1,1610038173;jean85,pretty-package-versions,i1.6.0,1612455616;symfony,lock,iv4.2.12,1561965886，哪里没有关键的“漏洞”

如果我第二次重新运行 composer install 没有问题。有人知道为什么吗？

1.8.0 中的作曲家版本

Answer 1

我突然无缘无故出现了同样的错误。我试图找到罪魁祸首，但开始花费的时间太长了。

我通过升级软件包修复了它。

1-尝试将 Composer 从版本 1 升级到版本 2（2.0.13 对我有用）。

//Check your composer version 
composer -v

2-确保完全升级到 Symfony 4.4。*（就我而言，我的某些组件使用的是 4.2-4.3 版）按照以下步骤操作：https://symfony.com/doc/current/setup/upgrade_minor.html

Symfony flex 1.12.2 版在 symfony 4.4 中为我工作

我以前认为 4.4 对我来说会崩溃，但事实并非如此。我的错误是之前尝试升级到 4.3。跳过那个！

与 V4 中的其他次要版本不同，还支持 2022 年 11 月之前的 4.4。
