RHEL 8 nodejs conflicts with JupyterHub-needed repos: nodesource-nodejs/nodesource-nsolid

Get Help
1

On RHEL 8 running dnf install ondemand --best --allowerasing results in the following conflicts. The server also runs JupyterHub which needed these 2 repos:

-rw-r--r--  1 root root   262 Mar  5 09:27 nodesource-nodejs.repo
-rw-r--r--  1 root root   262 Mar  5 09:27 nodesource-nsolid.repo

I’ve set enabled=0 on those 2. I also ran into the conflicts mentioned here.

 Problem: package ondemand-3.1.1-1.el8.x86_64 from ondemand-web requires ondemand-nodejs = 3.1.5-1.el8, but none of the providers can be installed
  - cannot install the best candidate for the job
  - nothing provides nodejs >= 1:18.0 needed by ondemand-nodejs-3.1.5-1.el8.x86_64 from ondemand-web
  - nothing provides nodejs < 1:19.0 needed by ondemand-nodejs-3.1.5-1.el8.x86_64 from ondemand-web
  - nothing provides npm needed by ondemand-nodejs-3.1.5-1.el8.x86_64 from ondemand-web

Is there a way around this?

Hi and welcome.

Sorry for the trouble with the install. What version of nodejs are you using?

You may want to checkout the dependency updates if you haven’t yet:

3

I uninstalled it:

rpm -qa|grep -i node
nodesource-release-el8-1.noarch

Which ones are you referring to? You quoted this discussion.

4

It’s likely a conflict from these instructions for JupyterHub:

# install nodejs and npm
curl –sL https://rpm.nodesource.com/setup_10.x | sudo bash -; yum install –y nodejs 

# install configurable-http-proxy
npm install -g configurable-http-proxy install

But what’s the fix?

5

I’m not sure of a fix from the current situation.

It looks like you simply have the wrong version of nodejs installed. The dependencies state 18 is needed. But, setup_10.x looks to be nodejs 10 not 18:

#!/bin/bash
...
# Script to install the NodeSource Node.js 10.x repo onto an
# Enterprise Linux or Fedora Core based system.
...

Try again with setup_18.x and see if that gives you better luck.

Ah yes I checked my cmd history:

curl –sL https://rpm.nodesource.com/setup_18.x | sudo bash -; yum install  nodejs -y
curl: (3) Failed to convert –sL to ACE; string contains a disallowed character

It seems like they have a dependency conflict where the nodejs versions don’t match up. I really don’t know how to solve that as you are trying to install both OOD which I do know about, and JupyterHub which i don’t know about, on the same server.

Are you able to install these on different servers/vm’s?

8

Yes we have an older version on another cluster but I’m trying to get these both working on the same server for testing purposes.

9

I think segmentation is the only way forward here. You are trying to install these 2 pieces of software and they have fundamentally different requirements and there’s just no way around that unfortunately.
