Php 编写器错误：安装失败，将./composer.json还原为其原始内容

我尝试通过composer安装我的php项目

composer.json：

{
    "require": {
        "Intervention/image": "~2.3.7",
        "intervention/image": "^2.3",
        "guzzlehttp/guzzle": "^6.2" 
    }
}

我运行以下命令：

composer require google/apiclient:^2.0

结果：

./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1

Installation failed, reverting ./composer.json to its original content.

此外，我还安装了

php composer.phar require guzzlehttp/guzzle

，在…

之前，我会尝试删除您的项目对

guzzlehttp/guzzle

的要求，并让您的谷歌依赖项告诉composer它想要的版本。谷歌的软件包（出于某种原因）的http/psr7的最低版本为1.2，而composer则抱怨说，它不知道如何满足这一要求

由于您的新依赖项（谷歌软件包）也需要

guzzlehttp/guzzle

，因此您不需要特别要求它，因此我只需删除它，然后再次尝试

composer update

。
