sudo apt-get install ros-<distro>-tf2-sensor-msgs

Please replace `<distro>` with the name of your ROS distribution, such as "melodic" or "noetic", and then run the command in the terminal:
```
sudo apt-get install ros-<distro>-tf2-sensor-msgs
```
For example, if you are using ROS Melodic, the command would be:
```
sudo apt-get install ros-melodic-tf2-sensor-msgs
```
This should install the "tf2_sensor_msgs" package and resolve the error message you encountered.

sudo apt-get install ros-<distro>-yocs-msgs
这是一个 ROS(Robot Operating System)命令,用于在 Ubuntu 系统上安装 ROS 中的 yocs_msgs 软件包。其中 `<distro>` 部分是 ROS 版本号,例如 kinetic、melodic 等。你需要将 `<distro>` 替换为你正在使用的 ROS 版本号,然后在终端中执行该命令即可完成安装。例如,如果你正在使用 ROS Melodic 版本,则可以执行以下命令进行安装:
```
sudo apt-get install ros-melodic-yocs-msgs
```
注意:在执行该命令之前,你需要先安装 ROS 系统。

这个编译错误是因为链接器找不到tf库的符号引用。tf库是一个用于处理坐标变换的库,它提供了TransformListener和Transformer等类。
要解决这个问题,你需要确保tf库正确地链接到你的项目中。以下是一些可能的解决方法:
1. 确保tf库已经正确地安装在你的系统中。如果你使用的是ROS,可以通过运行以下命令来安装tf库:
```
sudo apt-get install ros-<distro>-tf
```
这里的 `<distro>` 是你正在使用的ROS发行版,例如`melodic`或`noetic`。
2. 确保在你的CMakeLists.txt文件中正确地添加了tf库的依赖项。你可以在`find_package`命令后添加以下行来链接tf库:
```
target_link_libraries(your_target_name ${catkin_LIBRARIES} tf)
```
这里的 `your_target_name` 是你的目标可执行文件的名称。
3. 如果你的项目使用了其他依赖项,例如tf2或tf2_ros,你可能还需要添加它们的链接库。例如:
```
target_link_libraries(your_target_name ${catkin_LIBRARIES} tf tf2 tf2_ros)
```
4. 确保你的源代码文件中包含了正确的头文件引用。对于tf库,你可能需要包含`<tf/transform_listener.h>`和`<tf/transform_broadcaster.h>`。
尝试以上方法后,重新编译你的项目,应该能够解决链接错误。如果问题仍然存在,请确保在编译过程中没有其他错误或警告,并仔细检查你的代码和编译配置。
