【问题描述】：

我想在我的 Laravel 5.3 项目中集成 paypal。我想使用 sger/laravel-paypal 包。

当我使用 composer require sger/laravle-paypal 来安装这个包时，composer 会报告我这个错误：

Using version ^0.1.0 for sger/laravel-paypal
./composer.json has been updated
> php artisan clear-compiled
Loading composer repositories with package information
Warning: Accessing php-repo.foticos.com over http which is an insecure protocol.
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for sger/laravel-paypal ^0.1.0 -> satisfiable by sger/laravel-paypal[0.1].
    - sger/laravel-paypal 0.1 requires paypal/rest-api-sdk-php 1.7.* -> satisfiable by paypal/rest-api-sdk-php[1.7.2, 1.7.3, 1.7.4, v1.7.0, v1.7.1].
    - paypal/rest-api-sdk-php 1.7.2 requires psr/log 1.0.0 -> satisfiable by psr/log[1.0.0].
    - paypal/rest-api-sdk-php 1.7.3 requires psr/log 1.0.0 -> satisfiable by psr/log[1.0.0].
    - paypal/rest-api-sdk-php 1.7.4 requires psr/log 1.0.0 -> satisfiable by psr/log[1.0.0].
    - paypal/rest-api-sdk-php v1.7.0 requires psr/log 1.0.0 -> satisfiable by psr/log[1.0.0].
    - paypal/rest-api-sdk-php v1.7.1 requires psr/log 1.0.0 -> satisfiable by psr/log[1.0.0].
    - Conclusion: don't install psr/log 1.0.0


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

这是我的 composer.json 文件：

【问题讨论】：

在此之前尝试此命令：“composer require psr/log”

【参考方案1】：

这就是我设法安装它的方式：

$ composer require psr/log 1.0.0

$ composer require paypal/rest-api-sdk-php 1.7.*

$ composer require sger/laravel-paypal 0.1.0

注意：

paypal/rest-api-sdk-php 1.7.* 需要 psr/log 1.0.0 -> 可满足 通过

psr/log[1.0.0]

sger/laravel-paypal 0.1 需要

贝宝/rest-api-sdk-php 1.7.*

【参考方案2】：

如错误所示，您尝试安装的软件包需要 psr/log 的 1.0.0 版本，如果您检查您的 composer.lock 文件，您已经拥有的软件包的所有其他要求都需要 ^1.0 或 ~1.0它的版本，在撰写本文时，这将解析为1.1.0。 考虑到您尝试要求的软件包恰好需要 1.0.0，现在您的整套要求规则将解析为 1.0.0 您可以先删除您的composer.lock 文件和供应商文件夹，然后将"sger/laravel-paypal": "^0.1.0", 添加到您的composer.json 文件的要求中，然后再次执行composer install。
