Render deploys should work after upgrade to Yarn 4

[kbighorse]

Upgrading to Yarn 4 also broke Render deploys.

see #1496

and

[kbighorse]

does anyone have an opinion on this? Are people just not deploying current bullet-train apps to Render atm?

@kbighorse I don't use Render so I don't know if this will work, but you might try altering your render.yaml so that the buildCommand line looks like this:

buildCommand: "corepack enable && yarn && ./bin/render-build.sh"

Or alternatively you might try updating bin/render-build.sh to look like this:

#!/usr/bin/env bash
# exit on error
set -o errexit

corepack enable
yarn

bundle install
bundle exec rake assets:precompile
bundle exec rake assets:clean

# These are not combined because we want to reload all models after the migrations take place.
# TODO Any way to read these from the `Procfile` where we have the same thing defined for Heroku?
bundle exec rails db:migrate 
bundle exec rails db:seed

Reference: https://community.redwoodjs.com/t/deployment-to-render-yarn-versions/5789

And based on the link you shared it look like you might have to set the SKIP_INSTALL_DEPS ENV var to true, but I don't know how or where you'd do that.

Please report back if you give this a try. If it works we can add it to the repo.

I have an open request on the render community forum. I tried a ton of options and I haven't been able to figure out what I'm missing...

render forum thread

I'll update the render.yaml and render-build.sh once I've got a working version

My working changes:

render.yaml

services:
  - type: web
    name: web
    env: ruby
    buildCommand: "./bin/render-build.sh"
    startCommand: "bundle exec puma -C config/puma.rb"
    envVars:
      - key: SKIP_INSTALL_DEPS
        value: true

bin/render-build.sh

#!/usr/bin/env bash
# exit on error
set -o errexit

echo "bundle install starting..."
bundle install

echo "enabling corepack..."
corepack enable 
echo "corepack install..."
corepack install
echo "running yarn..."
yarn

echo "setting yarn version..."
yarn set version 4.2.2

echo "assets precompile starting..."
bundle exec rake assets:precompile

echo "assets clean starting..."
bundle exec rake assets:clean

echo "db:migrate starting..."
bundle exec rails db:migrate 
echo "db:seed starting..."
bundle exec rails db:seed

The current output error in render is

error This project's package.json defines "packageManager": "[email protected]". However the current global version of Yarn is 1.22.22.
Presence of the "packageManager" field indicates that the project is meant to be used with Corepack, a tool included by default with all official Node.js distributions starting from 16.9 and 14.19.
Corepack must currently be enabled by running corepack enable in your terminal. For more information, check out https://yarnpkg.com/corepack.

edit: even going as far as removing the packageManager from the package.json didn't fix the issue and the error still complained about the variable in the package.json.... I'm so confused.
