PHP将Facebook SDK添加到作曲家

Question

我正在阅读此官方Facebook https://developers.facebook.com/docs/php/gettingstarted/4.0.0页面。

我想将Facebook SDK添加到我的项目中

我试图做到这一点： composer require facebook/php-sdk在我的项目的根目录中composer require facebook/php-sdk ，我得到了

Warning: This development build of composer is over 30 days old. It is recommend
ed to update it by running "C:\ProgramData\ComposerSetup\bin\composer.phar self-
update" to get the latest version.
Please provide a version constraint for the facebook/php-sdk requirement: **4**

如您所见，我选择了4，然后收到此错误消息：

./composer.json has been updated
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 facebook/php-sdk could not be found in any version,
there may be a typo in the package name.

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

or more details.

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

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

为什么要这样？ 请注意，我没有向composer.json添加任何内容。

我打开composer.json并发现以下行：

"require": {
        "laravel/framework": "4.2.*"
    },

所以我应该将其更改为：

"require": {
        "laravel/framework": "4.2.*",
          "facebook/php-sdk-v4" : "4.0.*" 
    },

还是应该保留它并添加一个新的require实体，如下所示：

"require" : {
    "facebook/php-sdk-v4" : "4.0.*"
  }

Answer 1

只需尝试将facebook/php-sdk-4到现有的require哈希中，然后运行composer update 。

"require": {
    "laravel/framework": "4.2.*",
    "facebook/php-sdk-v4" : "4.0.*" 
}
