使用 composer

如何解决使用 composer

我尝试使用以下命令安装特定的电子表格库：

composer 需要 PHPoffice/PHPspreadsheet:1.8.2（因为我有 PHP5 版本）

我有这个错误：

无法将您的要求解析为一组可安装的软件包。

问题 1

- symfony/symfony is locked to version v3.4.10 and an update of this package was not requested.

- Only one of these can be installed: symfony/twig-bundle[v3.4.26],symfony/symfony[v3.4.10]. symfony/symfony replaces symfony/twig-bundle and thus cannot coexist with it.

- symfony/twig-bundle is locked to version v3.4.26 and an update of this package was not requested.

我的 composer.json：

有人有想法吗？

解决方法

symfony/symfony 是一个包含 Symfony 框架所有组件的包。这也包含 symfony/twig-bundle。无需安装这两个软件包，因此您可以安全地删除 symfony/twig-bundle。之后，应该可以添加您想要添加的任何包
