phpspreadsheet 作曲家没有安装

Question

我在本地运行 composer 生成必要的文件，然后我将这些文件单独部署到服务器。所以我是运行:

composer require phpoffice/phpspreadsheet --ignore-platform-reqs

但是，它失败了：

Problem 1
    - The requested package phpoffice/phpspreadsheet No version set (parsed as 1.0.0) is satisfiable by phpoffice/phpspreadsheet[No version set (parsed as 1.0.0)] but these conflict with your requirements or minimum-stability.

我对作曲家不熟悉。我已经通过将 "phpoffice/phpspreadsheet":"^1.0" 添加到 composer.json 来尝试此处建议的解决方案 https://github.com/google/google-api-php-client/issues/971，但这没有用。我也试过将最低稳定性设置为 dev 但没有成功。

有人可以帮忙吗？

我安装了 PHP 7.2，完整版。json 与 https://github.com/PHPOffice/PhpSpreadsheet

Answer 1

好的，所以这个答案是给其他任何发现这个作曲家新手的人的：

我假设 composer 会访问我已经从 GIT 下载的本地文件来配置所有内容。所以我运行在库源目录中使用 composer 命令。

这不是它的工作原理。您需要从您的项目目录中运行 composer 命令，它将通过互联网拉取文件并 'install' 它们在您的项目目录结构中。
