xviz github的的指南中有以下步骤：
# Download KITTI data $ ./scripts/download-kitti-data.sh # Convert KITTI data if necessary and run the XVIZ Server and Client $ ./scripts/run-kitti-example.sh
其中在转换kitti数据为XVIZ的数据过程中，执行./scripts/run-kitti-example.sh报错“gyp ERR! Node-gyp failed to build your package”，详细如下：

解决方法，进入xviz/examples/converters/kitti目录，执行sudo yarn add node-gyp -g：
004:~/myworkspaces/vueworkspace/xviz/examples/converters/kitti$ sudo yarn add node-gyp -g
安装完成后再执行./scripts/run-kitti-example.sh即可正常生成xviz的glb文件：
