即使安装了正确的 php 版本，为什么在 Composer 安装期间为过时的 php 版本出现版本不匹配? [英] Why do I get a version mismatch during composer install for an outdated php version even though correct php version is installed?
本文介绍了即使安装了正确的 php 版本，为什么在 Composer 安装期间为过时的 php 版本出现版本不匹配?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
鉴于非常基础的 composer.json:
{
"name": "kopernikus/fizzbuzz",
"description": "FizzBuzz!",
"type": "project",
"require": {
"php": "^7.0"
},
"require-dev": {
"phpunit/phpunit": "^6.5"
},
"license": "MIT",
"authors": [
{
"name": "Philipp Kretzschmar",
"email": "philipp.kretzschmar@gmail.com"
}
]
}
如果我跑:
$ composer install
我明白了:
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

为什么我只安装了 php@7，composer 却认为我在运行 php@5.5?
Why does composer think I am running php@5.5 even though I only have php@7 installed?
推荐答案
检查你的 Composer 配置，你已经覆盖了你的 平台 设置.
Check your composer config, you have overwritten your platform settings.
这在日志行中变得明显:
This becomes apparent by the log line:
- phpunit/phpunit 5.5.4 requires php ^5.6 || ^7.0 -> your PHP version (7.0.26-2+ubuntu16.04.1+deb.sury.org+2) overridden by "config.platform.php" version (5.5) does not satisfy that requirement.
重要的一点:
your PHP version (7...) overridden by "config.platform.php" version (5.5)
此外，您可以通过以下方式查看它是否设置:
Also, you can see if it is set via:
$ composer config platform.php
5.5
它对于构建机器很有用，这样 composer 可以在运行不同 php 版本的机器上安装依赖项.但它不应该一直存在于我的开发机器上.
It's useful for build machines so that composer can install dependencies on machines running different php versions. Yet it should not have persisted on my development machine.
我过去将平台设置为 5.5 仍然能够 composer install php7 下的 php5 项目，即使 composer install --ignore-platform-reqs 会足够了，或者也可以在项目级别设置平台配置.我在全局配置中有它:
I set the platform to 5.5 in the past to still be able to composer install a php5 project under php7 even though composer install --ignore-platform-reqs would suffice or one could set the platform config on a project level as well. I had it in the global config though:
$ jq . ~/.composer/config.json
{
"config": {
"platform": {
"php": "5.5"
}
}
}
在较新的作曲家版本上，配置湾是:
On newer composer version the config bay be part of the:
jq . ~/.config/composer/composer.json
{
"require": {
"hirak/prestissimo": "^0.3.7"
},
"config": {
"platform": {
"php": "5.5"
}
}
}
我也可能存在于您项目的 composer.json 中.
I might also exist within your project's composer.json.
我必须删除平台配置并且还必须composer update项目的composer.lock.仅删除配置是不够的.
I had to remove the platform config and had to composer update the project's composer.lock as well. Only removing the config did not suffice.
这篇关于即使安装了正确的 php 版本，为什么在 Composer 安装期间为过时的 php 版本出现版本不匹配?的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
