composer 无法在 symfony 3.4 中安装 knp 菜单包

Question

我尝试在 Symfony 3.4 中安装 knp-menu-bundle，但出现以下错误：

$作曲家需要knplabs/knp-menu-bundle开发大师

[InvalidArgumentException]

包 knplabs/knp-menu-bundle 版本 dev-master 的 PHP 要求与您的 PHP 版本 (5.5.9)

不兼容

奇怪，因为我的 PHP 版本是 7.1 而不是 5.5.9。

正在更新我的 post 以显示我的 composer.json。

Answer 1

尝试在 composer require knplabs/knp-menu-bundle "^2.0" 下面不使用 dev-master 或更改：

 "require": {
        "php": ">=7.0",
        ...............

Answer 2

问题是 knplabs/knp-menu-bundle 需要以下内容：

"php": "^5.6 || ^7",

你可以看到 here。但是您的 composer.json 有：

"php": ">=5.5.9",

所以你至少需要 5.6 才能使 knp-menu-bundle 依赖项满意。您仍然需要检查是否也适用于所有其他依赖项。
