创建项目laravel错误packagist.org

Question

当我使用composer create-project --prefer-dist laravel/laravel project像这样的错误

Content-Length mismatch
http://packagist.org could not be fully loaded, package information was loaded from the local cache and may be out of date

。我搜索了什么问题，但是大多数问题是当update composer并且必须更改url包时。但我想做一个新项目。我该如何解决。

Answer 1

首先，运行：

$ composer config --list --global        //this will get the composer home path.
[home] /root/.composer                   //it's my composer home path.

然后，在[home]目录中编辑config.json，使其像这样：
{
  "config": {
    "github-protocols": [
      "https,ssh"
    ]
  },
  "repositories": {
    "packagist": {
      "type": "composer",
      "url": "https://packagist.org"
    }
  }
}

这将使packagist连接强制为https。而且您还可以在项目中配置composer.json，这是一个laravel示例，如下所示：
{
  "name": "laravel/laravel",
  "description": "The Laravel Framework.",
  "keywords": [
    "framework",
    "laravel"
  ],
  "license": "MIT",
  "type": "project",
  "require": {
    "php": ">=5.5.9",
    "laravel/framework": "5.2.*"
  },
  "config": {
    "preferred-install": "dist"
  },
  "repositories": {
    "packagist": {
      "type": "composer",
      "url": "https://packagist.org"
    }
  }
}
