在 Composer 中创建项目时如何使用全局 composer.json？答案

【问题描述】：

我添加了以下配置，如果我需要全局包，一切正常。每个包都会从 mirrors.aliyun.com 安装

composer global config repo.packagist composer https://mirrors.aliyun.com/composer/

以及来自~/.composer/composer.json的内容

{
    "require": {
        "laravel/installer": "^4.0",
        "laravel/valet": "^2.11"
    },
    "repositories": {
        "packagist": {
            "type": "composer",
            "url": "https://mirrors.aliyun.com/composer/"
        }
    }
}

但是如果我用这样的作曲家创建项目，我发现包从https://repo.packagist.org/packages.json下载

composer create-project --prefer-dist laravel/laravel sample.com -vvv

我需要从镜像下载，但是全局composer.json中的配置被忽略了，有人知道这是为什么吗？

这是一些相关的日志

我添加--repository参数，然后从镜像仓库下载laravel/laravel模板

composer create-project laravel/laravel sample.com --prefer-dist --repository=https://mirrors.aliyun.com/composer/ -vvv

但是下载laravel/laravel之后，还是从Packagist下载，这里有一些相关日志

我自己找到了答案。

不要使用以下方法设置镜像，因为它们会修改~/.composer/composer.json，而composer.json在创建项目时将不起作用

composer global config repo.packagist composer https://mirrors.aliyun.com/composer/

正确的方式-手动将以下代码放入~/.composer/config.json，无论composer global require还是composer create-project，它们都会从镜像站点获取文件，而不是从packagist.org获取文件

{
    "config": {},
    "repositories": [
        {
            "type": "composer",
            "url": "https://mirrors.aliyun.com/composer/"
        },
        {
            "packagist": false
        }
    ]
}

无需在~/.composer/composer.json添加任何仓库相关配置

{
    "require": {
        "laravel/installer": "^4.0",
        "laravel/valet": "^2.11"
    }
}
