作曲者：找不到要求的套件php [英] Composer: The requested package php could not be found

问题描述

每次尝试运行 composer install 时，依赖项都会由于以下错误而失败：

Every time i try and run composer install, the dependencies fail due to the following error:

The requested package php could not be found

我知道了在LAMP堆栈上工作，但是我现在尝试在php5-fpm上使其在LEMP堆栈上工作，并且运行不正常。

I've got this working on a LAMP stack, but I'm trying to get it working on a LEMP stack now, with php5-fpm and its not going well.

$ php -v

EDIT

我还有其他东西，但是我在同一位置测试了以下 composer.json

I have other stuff in mine, but i tested the following composer.json on the same server, and its still doing it.

composer.json

{
   "require": {
        "php": "5.4.*"
    }
}

我的作曲家版本是

Composer version b7a9ea4187bce63f418bf7ba035b63dcb1e23ef6 2014-02-06 22:07:47

我错过了什么吗？

推荐答案

好吧，这很简单：Composer确实在做什么

Well, that's easy: Composer is exactly doing what you tell it to do.

您正在请求任何版本的PHP 5.4。您明确不允许使用任何5.5版本。因此Composer会正确地抱怨没有正确的PHP版本（您的PHP是PHP 5.5，您要求5.4。*。）。

You are requesting any version of PHP 5.4. You explicitly do not allow any versions of 5.5. So Composer correctly complains about having not the right version of PHP (yours is PHP 5.5, you request 5.4.*).

代码不太可能无法运行使用较新的版本，因此最好使用以下 composer.json 内容：

It is very unlikely that your code does not run with the newer version, so it's best to use this composer.json content:

{
    "require": {
        "php": ">=5.4"
    }
}

请求大于或等于5.4的版本还将包括5.5及更高版本。

Requesting a version greater than or equal 5.4 will also include 5.5 and above.
