在Paypal上使用Merchant SDK for Express Checkout API的作曲家问题

Question

I want to integrate a method from which a guest also can do payments on my site. So, i am implementing this SDK of paypal. It is required to install the compser and run it for dependencies. So, i ran this command to install composer.phar file inside samples folder

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

then to install composer i ran this command:

php composer.phar install

But it is showing error as

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.

Not sure why i am getting error of version 1.0.0 when i explicitly defining the version number i.e v3.8.107 This is the composer.json file which i am using. Can anyone help me know what is the issue and why can't i install the composer correctly. Am i missing any thing?

Answer 1

Try just the following in your composer.json:

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