由于 symfony/http-kernel 依赖，sentry-sentry-symfony 不会安装在 Symfony 2.8 上答案

【问题标题】：sentry-sentry-symfony won't install on Symfony 2.8 due to symfony/http-kernel dependency由于 symfony/http-kernel 依赖，sentry-sentry-symfony 不会安装在 Symfony 2.8 上
【发布时间】：2019-06-18 06:30:37
【问题描述】：

我有一个 Symfony 2.8 项目，我正在尝试安装 sentry/sentry-symfony。为此，我正在运行“composer require sentry/sentry-symfony”。

据我了解，这个哨兵库与 Symfony 2.x 兼容，但看起来它需要 symfony/http-kernel 3 或更高版本。

我的 composer.json 文件有以下...

    "require": {
        "php": ">=5.3.3",
        "symfony/symfony": "2.8.*",
        "doctrine/orm": "~2.2,>=2.2.3",
        "doctrine/doctrine-bundle": "~1.2",
        "symfony/assetic-bundle": "~2.3",
        "symfony/swiftmailer-bundle": "~2.3",
        "symfony/monolog-bundle": "~2.4",
        "sensio/distribution-bundle": "~3.0.12",
        "sensio/framework-extra-bundle": "~3.0",
        "incenteev/composer-parameter-handler": "~2.0",
        "knplabs/knp-paginator-bundle": "~2.4",
    "stripe/stripe-php": "^3.7",
    "twig/extensions": "^1.0"
    },

当我尝试执行 composer require 时会发生这种情况...

标签： php symfony composer-php sentry

【解决方案1】：

您不能将 Sentry 2.x 与 Symfony 2.x 一起使用。

来自documentation：

2.x 在 master 分支上积极维护，但需要 Symfony 3+ 和 PHP 7.1+；

1.x 仍然支持 Symfony 2 和 PHP 5.6/7.0；它可能会从主分支接收功能的反向移植，但不能保证

要安装 1.x 版，请使用

composer require sentry/sentry-symfony "<2"

这将安装最新版本低于 2
