Php 同时安装Composer依赖项

运行composer install以获取弹性搜索时，出现以下错误：

  Problem 1
    - Installation request for tamayo/laravel-scout-elastic 1.0.1 -> satisfiable by tamayo/laravel-scout-elastic[1.0.1].
    - tamayo/laravel-scout-elastic 1.0.1 requires elasticsearch/elasticsearch ^2.2 -> no matching package found.

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting
   see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.

如何让这些软件包一起安装？

尝试清理Composer的缓存

您的DEP（至少有3个已发布）工作正常，只需将它们安装到我的机器上即可

还有我的

composer.json

    "elasticsearch/elasticsearch": "^2.2",
    "tamayo/laravel-scout-elastic": "^1.0"
  }
}

所以我试过了，但仍然不起作用。当我一个接一个地运行composer时，它们安装得很好。问题是在新部署上，当composer安装运行时，正如我在回答中所说的，我无法重现这个问题。让我们先定义复制它的步骤。我的部署是新的，我也点击了

composer安装

。所以从零开始，没有供应商文件夹。在composer.json中运行composer install的这三件事给了我错误。它在我的本地机器和信号量上失败。我没有错误

composer.json

来自答案。Composer安装了软件包。所以我运行了Composer clearcache，需要做什么才能清除它

{
  "require": {
    "laravel/scout": "^1.1",
    "elasticsearch/elasticsearch": "^2.2",
    "tamayo/laravel-scout-elastic": "^1.0"
  }
}
