关于XTDrone在编译PX4文件夹时报错：Failed to connect to master in 30 seconds.

而且这一次的配置，是已经跑通过全流程的，但是更改了部分文件之后出现了px4编译不通过的现象。偶然发现PX4飞控EKF配置文件跟之前看见的不一样了。重新在ubuntu下网页下载px4包发现还是文件不对。在windows下打开文档下载px4的包，然后u盘拷到ubuntu下即可！博主配置了那么多次环境，还问了周围一圈人，都没碰到过这么奇怪的问题！抽象抽象抽象，真抽象哇。
根据xtDrone安装px4时遇到的不能连接rosmaster问题解决思路

之前老是显示[Err] [ConnectionManager.cc:121] Failed to connect to master in 30 seconds. [Err] [gazebo_shared.cc:78] Unable to initialize transport. [Err] [gazebo_client.cc:56] Unable to setup Gazebo。兜兜转转搞了好久都不行。先gazebo启动后，不关闭窗口，然后再开启一个终端来使用。用这个玄学方法终于成功了。
