node init.js UnhandledPromiseRejectionWarning: Error: The client is closed

[roger-OR-CAT]

This is my ifirst installation, but stuck on this issue.

Environment:

ubuntu 20.04
node -v: 11.15.0
npm: 6.7.0
redis-server: Redis version=6.0.6, bits=64 (installed from ppa:chris-lea/redis-server, as indicated on the requirements).

Cloning the pool and running npm update completed with warning and no errors. Ubuntu 20.04 comes with python3 by default, I installed python 2 before proceeding with npm update. Process completed with no problems.

node init.js fails at the beginning

Redis is available and running on the standard port:

~/pool$ redis-cli
127.0.0.1:6379> PING
PONG

Any clue?

R.

Solved: the Redis dependency on package.json must be 3.1.2
