Any help is appreciated. How can I upgrade the node “engine”?

Hey @LLawiet

The build image you are using is running an outdated and incompatible version of Node.js.

Using one of the methods outlined in the Manage Build Dependencies documentation to updated the version of Node.js used is the simplest.
Another option is to deploy a new site using the latest build image which runs Node.js v16. If you are using a custom domain, you could then remove them from the current site and add them to the new site.

If you have any questions, please don’t hesitate to reply.


Hey @coelmay,

I set the NODE_VERSION env variable to 12.22.0 and that worked! Thank you so much.

Can you help me understand:

  1. How can I ‘reset’ the image so it always use the latest version? Giving a little bit of context, I started the project from scratch again so that is the reason all the dependencies were different than what was on Netlify.

  2. I see other runtimes running like Ruby, PHP and Go. We’re not able to develop code in these languages yet correct?

To put it simply, Netlify deploys static websites so cannot deploy Ruby, PHP, [insert other dynamic language…] etc. You can however develop with Go in Netlify functions.

Yeah, I get it. I just find it interesting that all the other runtimes are there. I was hoping Netlify would support those anytime in the future :upside_down_face:

Also, the barrier between ‘static’ and dynamic is very blurry right now… We can run NextJS with SSR on Netlify…

Thanks for the article. I’ll check how to deploy serverless functions written in Go

Netlify supports all of these languages at build time, e.g. using Jeykll (Ruby), Cecil (PHP), Hugo (Go), etc. but not at runtime meaning you can’t deploy a PHP contact form.

Basically anything listed here:

Agree, this line seems a little blurry sometimes now. I don’t consider SSR as static, but more akin to PHP.
