这些消息到底是什么意思？我该怎么解决？
答案 0 :(得分：1)
在此报告中，您可以看到以下行，这意味着laravel-websockets需要illuminate/broadcasting 5.7、5.8或6.0+。它还为您提供了可以满足此要求的laravel/framework的所有版本（5.7.x-dev，5.8.x-dev，6.x-dev）：
- beyondcode/laravel-websockets 1.3.0 requires illuminate/broadcasting 5.7.* || 5.8.* || ^6.0 -> satisfiable by laravel/framework[5.7.x-dev, 5.8.x-dev, 6.x-dev], illuminate/broadcasting[5.7.17, 5.7.18, 5.7.19, 5.7.x-dev, 5.8.x-dev, 6.x-dev, v5.7.0, v5.7.1, v5.7.10, v5.7.11, v5.7.15, v5.7.2, v5.7.20, v5.7.21, v5.7.22, v5.7.23, v5.7.26, v5.7.27, v5.7.28, v5.7.3, v5.7.4, v5.7.5, v5.7.6, v5.7.7, v5.7.8, v5.7.9, v5.8.0, v5.8.11, v5.8.12, v5.8.14, v5.8.15, v5.8.17, v5.8.18, v5.8.19, v5.8.2, v5.8.20, v5.8.22, v5.8.24, v5.8.27, v5.8.28, v5.8.29, v5.8.3, v5.8.30, v5.8.31, v5.8.32, v5.8.33, v5.8.34, v5.8.35, v5.8.4, v5.8.8, v5.8.9, v6.0.0, v6.0.1, v6.0.2, v6.0.3, v6.0.4, v6.1.0, v6.2.0, v6.3.0, v6.4.1, v6.5.0].
在您的作曲家文件中，我们可以看到以下行，这意味着您在项目中仅允许5.6.x版本的Laravel：
// require
"laravel/framework": "5.6.*"
Composer只是告诉您不能在Laravel 5.6中使用laravel-websockets
这里的报告改写了：
尝试安装 laravel-websockets 1.3.0
正在检查依赖项...
laravel-websockets 1.3.0需要照明/广播 5.7、5.8或6.0+
但是照明/广播已在另一个版本中安装谁需要此照明/广播版本？
laravel / framework 做到了。它是否具有符合我的照明/广播要求的任何版本？
是的，它们是：5.7.x-dev，5.8.x-dev，6.x-dev我可以将 laravel / framework 升级到其中一个版本吗？
正在检查要求...
不， laravel / framework 不能超过5.6.x失败
