ViewsHow do I make Heroku use node 14.x instead of 12.x?
I need Heroku to use NodeJS 14 instead of 12, how do I do that? On my computer I'm using Node 14, and I'm defining it in engines on package.json (at the root of my repo):
{
"engines": {
"node": "14.x"
}
...
}
I have both the heorku/nodejs as well as the heroku/rails buildpack installed because this is a Ruby on Rails apps with webpack:
But when running my tests is Heroku, I get this error:
Error: Missing binding /app/node_modules/node-sass/vendor/linux-x64-72/binding.node
Node Sass could not find a binding for your current environment: Linux 64-bit with Node.js 12.x
Found bindings for the following environments:
- Linux 64-bit with Unsupported runtime (88)
If I workaround the problem in the CI, I still run into trouble when deploying:
-----> Installing node-v12.16.2-linux-x64
-----> Installing yarn-v1.22.4
-----> Detecting rake tasks
-----> Preparing app for Rails asset pipeline
Running: rake assets:precompile
yarn install v1.22.4
[1/5] Validating package.json...
error imok@0.1.0: The engine "node" is incompatible with this module. Expected version "14.x". Got "12.16.2"
error Found incompatible module.

In the documentation it says:
If you need a specific version of node for your Ruby application you should use multiple buildpacks to first install node then install Ruby.
which means if you deployed a Rails application, you need to remove all buildpacks and then re-add them in the correct order, first heroku/node and then heroku/rails.
