作曲家不能在symfony 3.4中安装knp菜单包

Question

我试图在Symfony 3.4中安装knp菜单包，但出现以下错误：

作曲家需要knplabs/knp-meno-bundle dev-master

[无效参数异常]

版本dev-master的包knplabs/knp-meno-bundle有一个与您的PHP版本不兼容的PHP需求（5.5.9）

这很奇怪，因为我的PHP版本是7.1而不是5.5.9。

更新我的帖子以显示我的composer.json。

Answer 1

问题在于KNPLAB/knp菜单包需要以下内容：

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

你可以在这里看到。但是，您的composer.json具有：

"php": ">=5.5.9",

所以你需要至少需要5.6才能让knp-menum-bundle依赖满意。您仍然需要检查是否所有其他依赖项都可以。

Answer 2

尝试只是没有dev-master下面的作曲家需要knplabs/knp-meno-bundle"^2.0"或更改：

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