这个错误信息表明你运行的launch文件smartcar_display.rviz.launch不存在于smartcar包中,或者smartcar不是一个有效的launch文件名。请检查一下路径和文件名是否正确。如果你确认路径和文件名正确,那可能是缺少了相应的依赖包。你可以通过查看日志文件来获取更详细的信息,帮助你解决问题。

根据你提供的信息,roslaunch启动失败了,并报告了一个错误。错误信息显示了不正确的XML语法,可能是由于在第2行第1列出现了一个无效的标记导致的。
你可以尝试检查smartcar_display.rviz.launch文件中的XML语法并确保其正确性。你还可以尝试在终端中使用roslaunch命令启动ROS节点,以查看是否会出现类似的错误信息,并进一步排除问题。

根据你提供的launch文件,你的URDF文件路径有问题。在第3行的`<arg>`标签中,你将`default`参数设置为以下值:
```
$(find xacro)/xacro '$(find smartcar)/urdf/smartcar.urdf.xacro'
```
这个值应该是一个有效的命令行字符串,用于加载URDF文件。然而,这个命令行字符串似乎不正确,因为它包含了两个`$(find)`占位符。正确的命令行字符串应该是:
```
$(find xacro)/xacro '$(find smartcar)/urdf/smartcar.urdf.xacro'
```
这个命令行字符串使用`xacro`工具来解析你的URDF文件,并将结果作为URDF文件的路径。请注意,你需要确保`smartcar.urdf.xacro`文件位于`smartcar`软件包的`urdf`目录下。
如果你仍然遇到问题,请检查命令行输出和启动日志,以获取更多信息。
