Questions & Answers

#1

I try to deploy the rails 6 App on platformsh, I have this error when deploying my project in Rails 6 with Webpacker 5.2.1.

I have done days of research on google, without success. I have NVM installed locally, node and npm, I will say that everything is fine locally, the webpacker is compiled correctly, but not on the remote machine. and this error makes the deployment fail.

    W: Webpacker requires Node.js ">=10.17.0" and you are using v6.17.1
    W: Please upgrade Node.js https://nodejs.org/en/download/
    W: Exiting!
  
  E: Error building project: Step failed with status code 1.

E: Error: Unable to build application, aborting.

when I want to compile the assets with this line on Build hook.

RAILS_ENV=production bundle exec rails webpacker:install

can you help me I’ll share my config

Hi @kam-vakaramoko. It looks like you’ll need to upgrade the version of Node.js in your Ruby container. Here is a guide for how to use NVM during the build hook to install whichever version you may need https://docs.platform.sh/languages/nodejs/nvm.html.
