Symfony / BrowserKit / Panther -- "don't install symfony/symfony v3...."

Question

我很难解决与 Symfony、BrowserKit 和 Panther 无头测试库相关的作曲家依赖管理问题。

我有三个基本环境，其中两个是相互关联的。

本地 Ubuntu 桌面，php 7.2.15 -- 工作
本地 Virtualbox 运行在 Ubuntu 本地 Ubuntu 桌面上，php 7.2.15 -- 失败
远程暂存服务器，php 7.2.10 -- 失败

命令：

SYMFONY_ENV=dev composer install

错误：

}

但是，如果我从 composer.json

的 "require-dev" 中删除以下行

    "symfony/panther": "^0.2.0",
    "symfony/browser-kit": "^4.2"

然后，它在所有三种环境中都有效！

当然，我会在运行每次测试之前删除我的 ./vendor 文件夹和 composer.lock 文件。

非常感谢任何帮助！

据我所知，symfony/panther 不支持您使用的 Symfony 3.4。

在 Symfony Panther GitHub 存储库中查看以下问题：#79 and #142

Symfony / BrowserKit / Panther -- "don't install symfony/symfony v3...."

Symfony / BrowserKit / Panther -- "don't install symfony/symfony v3...."

php

symfony

composer-php

symfony-3.4

symfony-panther
