使用php 7运行composer，但安装php 5软件包 [英] Use php 7 to run composer, but install packages for php 5

问题描述

我想使用安装在docker容器中的php 7运行composer，但最终的软件将在php 5上运行，因为多数民众赞成生产服务器正在运行。

I would like to run composer using php 7 installed inside a docker container, but the final software will run on php 5 since thats what the production server is running.

我没有看到为php 5安装软件和使用php 7 cli运行作曲者之间的任何关联，但似乎存在连接。

I don't see any correlation between installing software for php 5 and using php 7 cli to run composer, yet there appears to be a connection.

我怎么知道不管我运行哪个版本的composer，都无关紧要的是安装的软件包。

How can I tell composer that it doesn't matter what version I run composer with, what matters is the packages that it installs.

推荐答案

正确解决方案似乎是添加以下内容

The correct solution it seems is to add the following

"config": {
    "platform": {
        "php": "5.6.17"
    }
}

作曲家文件，那么它将用作您要尊重的php的版本。

to your composer file, then it will use that as the "version" of php you want to respect.
