build it no file

[wweizheng]

hello,when i run this colcon build --packages-select spl_lio_sam
the result is:
[0.162s] WARNING:colcon.colcon_core.package_selection:ignoring unknown package 'spl_lio_sam' in --packages-select
Summary: 0 packages finished [0.05s]

It says there is no file, what should I do next?

Did you start container according to the document and build inside container? and, notice to build in colcon workspace folder

我也遇到这个问题。检查发现splsam容器中codes目录为空，不知道是不是这个原因？

是不是因为下面这两条命令使用的不对呀？
export DATA_DIR=/path/to/download/ros2bag/dir
./docker_run.sh -c /path/to/code/repo -d $DATA_DIR
