无法使用composer在Windows上安装Mailgun库

Question

我一直在尝试使用composer在我的localhost中安装mailgun库。我在命令提示符下写了以下命令：

php composer require mailgun/mailgun-php:~1.3

它给我的错误为Could not open input file: composer

然后我尝试删除上一个命令开头的php：

composer require mailgun/mailgun-php:~1.3

它显示：

./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 mailgun/mailgun-php 1.0.0 could not be found.
Problem 2
- guzzle/guzzle v3.7.4 requires ext-curl * -> the requested PHP extension cu
rl is missing from your system.
- guzzle/guzzle v3.7.3 requires ext-curl * -> the requested PHP extension cu
rl is missing from your system.
- guzzle/guzzle v3.7.2 requires ext-curl * -> the requested PHP extension cu
rl is missing from your system.
- guzzle/guzzle v3.7.1 requires ext-curl * -> the requested PHP extension cu
rl is missing from your system.
- guzzle/guzzle v3.7.0 requires ext-curl * -> the requested PHP extension cu
rl is missing from your system.
- Installation request for guzzle/guzzle 3.7.* -> satisfiable by guzzle/guzz
le[v3.7.0, v3.7.1, v3.7.2, v3.7.3, v3.7.4].

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

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

我一直在努力安装mailgun几天，请帮助我。

更新

仅供参考：我使用的是使用xampp的Windows

composer.phar文件详细信息：

"name": "mailgun/mailgun-php",
"description": "The Mailgun SDK provides methods for all API functions.",
"require": {
    "guzzle/guzzle": "3.7.*"
},

    "phpunit/phpunit": "3.7.*"
},

Answer 1

mailgun使用guzzle，需要 php＆gt; = 5.3.3 和卷曲扩展

执行以下操作：

• 更新作曲家：composer self-update
• 检查php版本：php -v
• 安装curl扩展程序：[sudo] apt-get install php5-curl

如果您使用Windows，请尝试以下方法：

• WAMP Curl installation
• How to enable curl in xampp?
• How do I install cURL on Windows?

如果您仍然遇到composer require ...

错误

• 如果存在，请从项目的根目录中删除“composer.lock”文件。
• 在项目的根目录中创建“composer.json”文件，如下所示。
• 运行composer install

// composer.json：

{
    "require": {
        "mailgun/mailgun-php": "~1.5"
    }
}

Answer 2

作曲家需要mailgun / mailgun-php：~1.7.1

为我工作 - Windows，XAMPP。

找到你的php.ini并取消注释extension = php_curl.dll。
