Composer没有在PHP项目中安装依赖项

我试图将Paypal PHP SDK添加到我的项目中：

composer require "paypal/rest-api-sdk-php:*"

但我一直收到以下错误，并且作曲家没有将 \ vendor 添加到我的项目中。 

user@user:/opt/lampp/htdocs/projects/paypal/ipn$ composer require "paypal/rest-api-sdk-php:*"

我可能做错了什么？

提前谢谢大家。

这是我的应用程序的composer.json：

{
    "require" : {
        "paypal/rest-api-sdk-php" : "*"
    }
}

1 个答案:

答案 0 :(得分：3)

无法满足paypal/rest-api-sdk-php composer中指示的平台要求，这就是Problem 1 - The requested PHP extension ext-curl * is missing from your system. Install or enable PHP's curl extension. 拒绝安装软件包的原因：

--ignore-platform-reqs

要求包裹$ composer require paypal/rest-api-sdk-php --ignore-platform-reqs

如果你只关心需要包，你可以运行

php

供参考，请参阅composer.json：

  

- ignore-platform-reqs ：忽略hhvm，lib-*，ext-*和--ignore-platform-reqs要求并强行安装，即使本地机器不满足这些。另请参阅https://getcomposer.org/doc/03-cli.md#require配置选项。

使用composer.json

安装软件包

假设包

  • 已添加到composer.lock
  • composer.json与$ composer install --ignore-platform-reqs
    • 中的更改保持同步

你可以运行

php

供参考，请参阅platform：

  

- ignore-platform-reqs ：忽略hhvm，lib-*，ext-*和composer.lock要求并强行安装，即使本地机器不满足这些。另请参阅https://getcomposer.org/doc/03-cli.md#install配置选项。

要了解composer.json是否与$ composer validate 中的更改保持同步，请运行

ext/curl

注意：您可能仍然无法使用软件包，因为软件包依赖于要安装的ext/curl。要确保您可以在计算机上安装和使用该程序包，您应该在该计算机上安装func loadDataFromURL() { // Fetch URL let url = URL(string: "https://www.apple.com/nl/today/static/data/hub/1101000001001110001.json")! // Load Data let data = try! Data(contentsOf: url) // Deserialize JSON let json = try! JSONSerialization.jsonObject(with: data, options: .allowFragments) as? [String: AnyObject] let coursesJSON = json?["courses"] as? [AnyObject] for object in coursesJSON! { let id = object["id"] as! String if coursesDict[id] == nil { let name = object["shortName"] as! String let program = object["programName"] as! String let shortDescription = object["shortDesc"] as! String let mediumDescription = object["mediumDesc"] as! String let longDescription = object["longDesc"] as! String let imageURL = object["image"] as! String let tempCourse = Course(id: id, name: name, program: program, shortDescription: shortDescription, mediumDescription: mediumDescription, longDescription: longDescription, imageURL: imageURL) coursesDict[id] = tempCourse table.reloadData() } } print(coursesDict.count, "loadURL") } } 。
