解决依赖冲突安装Behat和Laravel 5.3

Question

您好我正在尝试通过composer安装behat / behat，但是我有依赖性问题。我试过以下很多：

composer require behat/behat:"3.*" symfony/dependency-injection:"3.*" --dev

但是，上面的输出是

Your requirements could not be resolved to an installable set of packages.

下面是我的composer.json文件。

}

我应该安装behat和symfony / dependency-injection的组合？我尝试了许多版本以下发出的命令 作曲家信息behat / behat -a但仍然无济于事。

Answer 1

基本上，每当您遇到此依赖性噩梦时，强烈建议您使用所需的特定版本而不是通配符。换句话说：给予Composer更少的想象空间。

这就是我做的工作：

1。猜猜哪个最合适

Laravel 5.3于2016年9月9日回归released，超过了Behat releases，这是2016年3月28日发布的第一个主要版本3.1.0。所以这是我在Composer 中直接放入的第一个版本（即没有任何通配符等），如下所示：

"behat/behat": "3.1.0",

2。运行没有附加字符串的东西

之后，我刚刚运行了以下内容：

• composer dump-autoload：清理缓存
• rm -rf vendor和rm composer.lock：只是为了让生活更轻松
• composer install --no-scripts：只是为了确保php artisan内容不会运行。
• 利润

composer show | grep behat
