Deploy to Heroku failed. move-file incompatible with node version

问题

I am struggling to deploy a new rails 6 app to heroku. It runs fine on my local. During the deployment process I receive the following output.

Unfortunately, I am new to webpack and yarn. It seems like a version / dependency issue with move-file which in turn seems to be a dependency for webpacker. However, I have no idea how to resolve this.

It seems to come down to this line:

error move-file@2.0.0: The engine "node" is incompatible with this module. Expected version ">=10.17". Got "10.15.3"

However, node is not one of my node-modules but seems to be an installed binary. When I run

node - v

I get: v12.16.1

Any help would be greatly appreciated.

If you need any further log or code samples, please let me know. I am at a loss.

===================== update:

I found the documentation about buildpacks and node on heroku: - https://devcenter.heroku.com/articles/nodejs-support

based on that, I changed my package.json file to look like this:

  },
  "version": "0.1.0",
  "engines": {
    "node": "12.16.x"
  },
  "devDependencies": {
    "webpack-dev-server": "^3.10.3"
  }

now, the error message has changed to:

remote:        Running: rake assets:precompile
remote:        yarn install v1.16.0
remote:        [1/5] Validating package.json...

I assumed the update in the package.json file would cause heroku to use the specified node version. However, it doesn't.

The question is: How can I define which node version heroku uses?

回答1:

It took some research to solve this. Heroku can apply multiple build packs per app. In that case, the order matters. I specified to run the nodejs buidlpack first and then the ruby buildpack. Only then will the "engine" definition in the package.json have an effect. If you use the ruby buildpack, the node version defaults to 10.15.3. However, if you execute the nodejs buildpack first, it will install the version specified in the package.json file. https://devcenter.heroku.com/articles/ruby-support#installed-binaries
