当我启动roslaunch septentrio_gnss_driver rover.launch param_file_name:=rover时，出现以下启动文件错误：

我已经通过`sudo apt install ros-noetic-septentrio-gnss-driver`安装了ROS Noetic的septentrio_gnss_driver。`

when I launch `roslaunch septentrio_gnss_driver rover.launch param_file_name:=rover
`
having following launch file for github [repo][1]
```xml
&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;

&lt;launch&gt;
  &lt;arg name=&quot;node_name&quot; default=&quot;septentrio_gnss&quot; /&gt;

  &lt;/node&gt;

&lt;/launch&gt;

I get following error

ERROR: cannot launch node of type [septentrio_gnss_driver/septentrio_gnss_driver_node]: Cannot locate node of type [septentrio_gnss_driver_node] in package [septentrio_gnss_driver]. Make sure file exists in package path and permission is set to executable (chmod +x)
I already install septentrio_gnss_driver for ros noetic by sudo apt install ros-noetic-septentrio-gnss-driver

对于软件包安装验证，您需要手动运行您在启动文件中编写的节点以执行。还尝试在编写节点名称之前按两次TAB键以检查是否找到软件包。

ros2 run <package_name> <node_name>

• 如果未找到节点，请检查此存储库，其中所有使用sudo安装的软件包都会进入：

/opt/ros/humble/lib/

• 列出所有软件包并找到您的。
• 我还制作了一个相关视频-> 链接。

英文:

For package installation verification you need to manually run the node you are writting in launch file to execute . Also try pressing double TAB key before writing node name to check if package was found.

> ros2 run <package_name> <node_name>

• If node is not found check this repository where all sudo installed package go into

> /opt/ros/humble/lib/

• List all packages and find yours .
• I have produced a video about it as well -> link
