Composer php PHPSReadSheet编写器未安装

我在本地运行composer来生成必要的文件，然后将这些文件单独部署到服务器。因此，我正在运行：

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

然而，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.

我对这位作曲家不熟悉。我尝试了这里建议的解决方案，在composer.json中添加了

“phpoffice/phpspreadsheet”：“^1.0”

，但没有成功。我还尝试将最小稳定性设置为

dev

，但没有成功

有人能帮忙吗

编辑更多信息***

我已经安装了PHP7.2，full.json与从

好的，这个答案适用于其他认为这是作曲家新手的人：

我假设composer将访问我已经从GIT下载的本地文件来配置所有内容。因此，我从库源目录中运行composer命令

这不是它的工作原理。您需要从项目目录中运行composer命令，它将通过internet提取文件并将其“安装”到项目目录结构中。

v1.0需要PHP5.6。您的PHP版本是否涵盖了这一点？你能分享整个

composer.json

和一些关于你的环境的版本信息吗？@NicoHaase我已经为这个问题添加了细节，但我也运行了composer，并标记了

--ignore platform reqs

，Thank.OMG，这太蹩脚了，没人提到这一点。。非常感谢您帮助我找到难以捉摸的autoload.php等：）
