Error on "./nodebb setup"

[Alligator]

Hello, I'm facing this error when I attempt a ./nodebb setup according to this tutorial:

Ubuntu (Recommended) - NodeBB Documentation

I'm trying this on a fresh Digital Ocean Droplet. Could anyone, please, help me out?

@alligator this is a thing that we need to fix, but for a temporary fix please use an older version of Node

[Ivorzk]

me too

[PitaJ]

@ivorzk this will be fixed in 1.17.0

I recommend you use Node 14 for now.

@ivorzk ah sorry it's actually the npm version that matters here. You need to downgrade to the previous major version:

npm install --global [email protected]

[Ivorzk]

@pitaj Thank you

I checked out v1.16.2 of the forum and was running node version 15.12 when I encountered the same error.
I downgraded to node version 14.6.0 and now this error is not coming up.

I hope this info can help anyone.
