[Slackware-current] can't install

On Slackware 15.1-current (n86-64) I can't install.

root@0.cosmos:~/pvc-0.8.14# make install
npm install
sed -e 's/@VERSION@/0.8.14/' -e 's/@DATE@/Tue 28 Jan, 2025/' pvc.1.in > pvc.1
npm error code 127
npm error path /root/pvc-0.8.14/node_modules/zlib

make: *** [Makefile:65: nodeModules] Error 127

Do I have to uninstall pvc v0.8.12 first, and were any my earlier issues solved?
