Unsupported engine node / NPM only when building in Docker - node.js

Question

I have a dependency in my package.json which itself has the following dependency:
"node-rdkafka": "^2.5.0",
Using nvm on my local machine and setting my node version to 8.9.1, and my npm version is 5.5.1, I can successfully run
npm install node-rdkafka#2.7.1
But when running the same thing (i.e npm install) from within my docker image:
FROM node:10.13.0-alpine or FROM node:8.9.1-alpine
I get the following error:
npm ERR! notsup Unsupported engine for node-rdkafka#2.7.1: wanted: {"node":">=12.0.0"} (current: {"node":"10.13.0","npm":"6.4.1"})
npm ERR! notsup Not compatible with your version of node/npm: node-rdkafka#2.7.1
npm ERR! notsup Not compatible with your version of node/npm: node-rdkafka#2.7.1
npm ERR! notsup Required: {"node":">=12.0.0"}
npm ERR! notsup Actual: {"npm":"6.4.1","node":"10.13.0"}
Any ideas about this inconsistency?
I clearly dont need a node version this high. But it says I do.

Answer 1

Try to remove package-lock.json before npm install in Docker
rm package-lock.json
npm i

Answer 2

The engines property in the package.json allows us to establish a range of versions.
With >=12 is asking for a node with version 12 or greater.
Therefore, the solution would be to install the requested version:
FROM node:12
Anyway, I recommend reviewing the versions supported by Docker currently here.
