how to build point cloud viewer?

[sunmk2006]

When I did the third step :“npm install", there was an error: npm WARN point_viewer@0.1.0 No repository field.

Did you work it out?

[sunmk2006]

build successfully, but：
viki@viki:/soft/point_cloud_viewer-master/target/release$ ls
build build_octree deps examples libpoint_viewer.rlib native viewer
viki@viki:/soft/point_cloud_viewer-master/target/release$ build_octree
build_octree: command not found
viki@viki:~/soft/point_cloud_viewer-master/target/release$

./build_octree generates a lot of files,but
./viewer /home/viki/source/data/cartographer_data/mode
Listening on port 5433.
IT seems to do nothing, No changes in memory and CPU ，What happened？

open your browser to http://localhost:5433, then left click and drag a bit. It should load your points. use WASD to fly around, mouse wheel to adjust speed.
