Composer 需要 phpoffice/phpspreadsheet 不起作用

我想使用 Phpspreadsheet 包编写一个脚本。我没有 php 经验。我正在尝试通过 sudo Composer require phpoffice/phpspreadsheet 添加对我的脚本的引用。但这不起作用。我收到错误：安装失败，删除composer.json...如果不知道为什么它不起作用。任何想法？

详细错误：

Problem 1

You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Installation failed, reverting ./composer.json to its original content.

所以我应该安装

sudo apt install php-xml

sudo apt install php7.0-gd

sudo apt install php7.0-mbstring

sudo apt install php-zip
