php - Merchant SDK for Express Checkout API 在 Paypal 上的 Composer 问题

Question

我想集成一种方法，访客也可以通过该方法在我的网站上进行付款。所以，我正在实现这个 Paypal 的SDK。需要安装 compser 并运行它以获取依赖项。所以，我运行了这个命令来在 samples 文件夹中安装 composer.phar 文件

curl -sS https://getcomposer.org/installer | php -- --install-dir=/var/www/html/app/paypaltest/samples

然后为了安装 Composer ，我运行了这个命令:

php composer.phar install

但是它显示错误为

Loading composer repositories with package information
Installing dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Problem 1
- The requested package paypal/merchant-sdk-php 1.0.0 could not be found.

Potential causes:
- A typo in the package name
- The package is not available in a stable-enough version according to your minimum-stability setting
  see <https://groups.google.com/d/topic/composer-dev/_g3ASeIFlrc/discussion> for more details.

Read <http://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.

不确定为什么当我明确定义版本号时出现版本 1.0.0 的错误，即 v3.8.107这是我正在使用的 composer.json 文件。任何人都可以帮助我知道问题是什么以及为什么我不能正确安装 Composer 。我错过了什么吗？

Answer 1

在您的 composer.json 中尝试以下内容:

{
    "require": {
        "paypal/merchant-sdk-php": "v3.8.107"
    }
}
