lucadegasperi/oauth2-server-laravel这个包，我也下载不了，报错Your requirements could not be resolved to an installable set of packages.

大神啊，这是编程，不是数学题啊。。。

我现在有一个点和一系列点，这一系列点形成了一条轨迹线，求这个点到这条轨迹线的最短距离。

有哪位大牛能给个算法，计算点到一条轨迹的距离?跪求

哥啊，都三个月了你还没有录呢，我都等三个月了，等的花都谢了~_~

我给你截图说吧，我觉得锚点的名字是一样的，就是不起作用

老大,这个消息跳转到锚点那为啥我的跳不到那去呢,id都是一样的,你的却能跳到相应的回复

点击消息通知跳转到回复的位置是怎么做到的？

我已经根据模型将数据查出来了，该怎么渲染到模板上呢？结构是这样的：

引用也是加了的，没起作用，还有没有别的比较好的markdown编辑器推荐的，总感觉这个样式贼难看，我发现laravel社区里的那个发送私信的支持粘贴图片的文本框就特别好，方便。

laravel5.5引用的这个编辑器没有实时预览效果，标题大小都没区别## 和###是一样的效果，这是为什么呢？为什么没解析呢
