在Paypal上安装Merchant SDK for Express Checkout API

Question

正如标题所示，我试图在PayPal上安装Merchant SDK for Express Checkout API。

composer.json

{ 
    "name": "paypal/merchant-sdk-php", 
    "description": "PayPal Merchant SDK for PHP", 
    "keywords": ["paypal", "php", "sdk"], 
    "homepage": "https://developer.paypal.com", 
    "license": "proprietary", 
    "authors": [ 
     { 
      "name": "PayPal", 
      "homepage": "https://github.com/paypal/merchant-sdk-php/contributors" 
     } 
    ], 
    "require": { 
       "php": ">=5.3", 
       "ext-curl": "*", 
       "paypal/merchant-sdk-php":"v3.6.106" 
      }, 
    "autoload": { 
     "psr-0": { 
      "PayPal\\Service": "lib/", 
      "PayPal\\CoreComponentTypes": "lib/", 
      "PayPal\\EBLBaseComponents": "lib/", 
      "PayPal\\EnhancedDataTypes": "lib/", 
      "PayPal\\PayPalAPI": "lib/" 
     } 
    } 
} 

当我运行composer update，这里是我的错误：我尝试安装的软件包，Button Manager的SDK

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 
    - 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 min 
imum-stability setting

problems. 

。这就要求我将"require"中的最后一行更改为"paypal/buttonmanager-sdk-php":"v3.6.106" 而且工作正常。

我不知道为什么在商家SDK的情况下搜索1.0.0版本，并报告找不到它的错误。

考虑我的指示，请提供一个洞察我的问题，如果需要也要求任何额外的信息。

Answer 1

在你的composer.json只保留所需的东西。如果您只创建需要通过作曲家安装的组件/软件包，则需要定义名称，描述，关键字等。

因此，为了您的项目需要任何软件包，只需保留软件包名称和版本名称即可。所以，你composer.json会像

{ 
    "require": { 
     "paypal/merchant-sdk-php": "3.6.106" 
    } 
} 

另外，可以通过composer require paypal/merchant-sdk-php做，并给予版本名称。
