我一直在尝试安装谷歌的ClientAPI，但它有大量的依赖性问题。我在网上搜索过，一点运气都没有。
我试图自己安装错误的依赖项，但它们有相同的问题。这是我得到的信息：
Your requirements could not be resolved to an installable set of packages.

Installation failed, reverting ./composer.json to its original content.
在这一点上，我所能想到的就是在composer之外安装ClientAPI，但我不知道这是否是一个好主意！
这是我的作曲家。json文件（仅相关部分）：
"minimum-stability": "dev",
"require": {
"php": ">=5.5.9",
"laravel/framework": "5.2.*",
"tymon/jwt-auth": "0.5.*",
"barryvdh/laravel-cors": "^0.8.0",
"laravel/socialite": "^2.0",
"guzzlehttp/guzzle": "^6.1",
"intervention/image": "^2.3",
"kozz/laravel-guzzle-provider": "^6.0",
"symfony/psr-http-message-bridge": "^0.2.0",
"fairholm/elasticquent": "dev-feature/laravel-5",
"graham-campbell/flysystem": "^3.3",
"league/flysystem-sftp": "^1.0",
"netshell/paypal": "dev-master",
"facebook/php-sdk-v4": "~5.0"
},
问题在于旧包需求和新包需求之间存在冲突。
这是作曲家最糟糕的部分，也是作曲家的缺点。
您必须手动安装一个包版本，它可以满足两个包。相信我，这很难做到。
我找到了一个关于GitHub谷歌API PHP客户端问题的解决方案和讨论。这实际上也解决了我的问题。参考原始帖子，这样它也可以挽救某人的一天。

其想法是直接将“google/apiclient”：“^2.0”添加到composer。json和正在运行的composer更新。
phpseclib/phpseclib的安装请求（锁定在0.3.10）
guzzlehttp/psr7的安装请求（锁定在1.4. x-dev）
似乎有些软件包在特定版本上被“锁定”（根据您的composer.lock）。
要查看它们被锁定的原因，请运行：
composer why org/package -t
您可以尝试通过以下方式更新这些依赖项：
composer update --with-dependencies
但是，如果没有帮助，考虑删除<代码>作曲家。锁定并重新运行composer安装。
在空文件夹上也尝试您的配置。
要查看已安装的依赖关系树，请运行：
composer show -t
要查看给定包的要求，请运行以下示例：
composer show -a google/apiclient 2.0.3
这可以让你知道什么是错的。要查看更详细的输出，请将-v添加到命令中。
