composer.json文件看起来像这样

我在更新之前完成了composer安装，以便下载所有依赖项。为了解决另一个错误，我对 composer.lock文件

的要求进行了一些小改动

            "php": ">=5.4.0",
            "symfony/process": "~2.6|~3.0"
        },

我无法删除上述错误，说明您的要求无法解决。请帮助我，提前致谢。

Answer 1

它对我有用，

请勿更改composer.lock文件。

第一个错误输出表明您尝试获取0.4.x 的barryvdh/laravel-async-queue版本，但该版本不适用于Laravel 5.4。

如果所有其他方法都失败了，请备份composer.lock并重新运行composer install。

Composer更新：无法将您的要求解析为可安装的软件包集
