我在更新之前完成了 composer install 以便下载所有依赖项。 为了修复另一个错误，我对 composer.lock 文件
的要求做了一些小改动"packages": [

我无法删除上述错误，即无法解决您的要求。请帮助我，在此先感谢。
【问题讨论】：
你运行的是什么 PHP 版本？在命令行输入 php -v 如果它是 @RobFonseca 先生，我不这么认为，因为我使用的是 PHP 7.0.15 版本。这是 PHP 的最新版本。 嗨@sameer，您正在使用包barryvdh/laravel-async-queue，版本为0.4.x。我认为对于 Laravel 5.4 你必须使用这个包的0.6.x 版本。我认为这可能会对您有所帮助。
@LuckySaini 先生，我通过将版本更改为 0.5.0 和 0.6.x 进行了尝试，但没有任何效果。仍然收到相同的错误消息。
【参考方案1】：
它对我有用，
不要更改 composer.lock 文件。
第一个错误输出表明您正在尝试获取 barryvdh/laravel-async-queue 的 0.4.x 版本它不适用于 Laravel 5.4。
如果一切都失败了，请备份您的 composer.lock 并重新运行 composer install。
