更新： @H_502_1@我实际发布了这个包,所以你可以自己看问题.

@H_502_1@在这里查看naomik/yamldump

@H_502_1@我正在尝试制作一个小的CLI工具并将其与作曲家打包在一起.

@H_502_1@下面是该程序的一个非常简化的版本,但它足以证明我遇到的问题.

@H_502_1@该项目有一个依赖项和一个“二进制”文件

@H_502_1@composer.json

{
  "name": "naomik/yamldump","version": "0.2.0","bin": [
    "bin/yamldump"
  ],"require": {
    "symfony/yaml": "2.5.3"
  }
}

@H_502_1@斌/ yamldump

#!/usr/bin/env PHP
<?PHP

// use Yaml namespace
use Symfony\Component\Yaml as Yaml;

// autoload
require_once "vendor/autoload.PHP";

// read yaml
$yaml = file_get_contents(sprintf("%s/%s",getcwd(),$argv[1]));

// create parser
$parser = new Yaml\Parser();

// parse the yaml
var_dump($parser->parse($yaml));

@H_502_1@因此,当我在全球范围内安装它时,我就明白了

$composer global require naomik/yamldump=dev-master

@H_502_1@文件已安装到

@H_502_1@>〜/ .composer / vendor / bin / yamldump – > ../naomik/yamldump/bin/yamldump
>〜/ .composer / vendor / naomik / yamldump /
>〜/ .composer / vendor / symfony / yaml /

@H_502_1@这是一个问题,因为我不打算全局安装symfony / yaml,我的软件包的vendor / autoload.PHP无法在正确的位置找到Yaml软件包.

@H_502_1@我不介意symfony / yaml是全局安装的,但是对我来说有意义的是,composer global require会安装这样的包：

@H_502_1@>〜/ .composer / vendor / bin / yamldump – > ../naomik/yamldump/bin/yamldump
>〜/ .composer / vendor / naomik / yamldump /
>〜/ .composer / vendor / naomik / yamldump / vendor / symfony / yaml /

@H_502_1@毕竟,如果我有依赖于symfony / yaml = 2.5.3的Package A和需要symfony / yaml = 2.6.x的Package B怎么办？

@H_502_1@如果composer global要求安装〜/ .composer / vendor / *的依赖项,那么每个全局需要的包都无法维护它自己的依赖项版本要求……

@H_502_1@我知道这是一个令人费解的问题,但我真的不知道如何开始修复它.

@H_502_1@目标

@H_502_1@用户应该能够

$composer global require naomik/yamldump=dev-master
$yamldump sample.yml

@H_502_1@错误

$yamldump sample.yml
Warning: require_once(vendor/autoload.PHP): Failed to open stream: No such file or directory in /Users/naomik/.composer/vendor/naomik/yamldump/bin/yamldump on line 8

Fatal error: require_once(): Failed opening required 'vendor/autoload.PHP' (include_path='.:') in /Users/naomik/.composer/vendor/naomik/yamldump/bin/yamldump on line 8

@H_502_1@这个问题

@H_502_1@这是黑色&白色：

@H_502_1@我打算如何编写require“vendor / autoload.PHP”行并让它适用于本地安装的软件包和全局安装的软件包？

require_once __DIR__.'/../vendor/autoload.PHP';

if (
    (!$classLoader = includeIfExists(__DIR__.'/../vendor/autoload.PHP')) &&
    (!$classLoader = includeIfExists(__DIR__.'/../../../autoload.PHP'))
) {
    echo 'You must set up the project dependencies,run the following commands:'.PHP_EOL.
        'curl -sS https://getcomposer.org/installer | PHP'.PHP_EOL.
        'PHP composer.phar install'.PHP_EOL;
    exit(1);
}
