答案

你的composer.lock是在运行PHP7.1的计算机上制作的，但是你的prod服务器运行的是7.0.22，或者你对（我猜）教条的版本限制太高了。要绕过第一个，将其添加到composer.json： ... "config": { "platform": { "php": "7.0.22" } } ...，运行composer update并检入生成的composer.lock文件。这样你就可以强迫composer为你的生产php版本选择包，它应该与你的开发版本（7.1）兼容。

另一答案

它比编辑composer.json更简单

例如，使用switch --ignore-platform-reqs和composer命令

composer update --ignore-platform-reqs
