bin/installDeps.sh - failing with unable to find `dezalgo` error

Using the latest 1.6.2, get the following error when trying to start up. It seems to come from the installDeps.sh

[root@2274172dfbae etherpad]# bin/installDeps.sh

Versions:

[root@2274172dfbae etherpad]# npm -v
5.6.0
[root@2274172dfbae etherpad]# node -v
v4.8.7

Any ideas?

to make it work with npm@5.6.0 : remove the src/package-lock.json

I removed all package-lock.json files and run bin/installDeps.sh with success
