composer Failed to decode response: zlib_decode(): data error 問題解決

首先用 composer diagnose 命令診斷下問題

然後他告訴我

Checking composer version: WARNING
You are not running the latest stable version, run `composer self-update` to update (1.7.2 => 1.9.0)

所以，我執行了下 composer self-update 命令

再次執行 composer require …… 成功了～
