nav2 teb

[1157354382]

小鱼儿你好，各位大佬好，我使用的的ubuntu20 Galactic
之前我使用的是 apt 安装的 nav2 ，并将 DWA替换成 TEB，并能正常导航，但是今天 我使用 源码编译安装 nav2后，使用 TEB 无法正常导航，报错如下：

[controller_server-8] [INFO] [1684587635.038695680] [controller_server]: Created controller : FollowPath of type teb_local_planner::TebLocalPlannerROS

我将 DWB 换回来后可以正常导航，请问这是什么原因呢。
另附上我的 teb 参数：

@1157354382 在 nav2 teb 中说：

源码编译安装 nav2后

估计是源码分支问题，注意分支和自己的当前分支保持一致

朋友你好，我用的humble版本的ROS2，将DWB替换成TEB以后没法进行导航，请问你在更换planner的时候除了将上面的代码替换掉原来的planner之外，还进行别的配置了吗？

@小鱼 大佬你好，我用的humble的ROS2，在将fishbot的DWB更换成TEB之后没办法导航，地图膨胀层和局部代价地图加载不出来，请问你知道是怎么回事吗，我只讲controller_server进行了替换，没有进行其他配置

[741390353]

地图是这个样子的
