You need to upgrade your Node Version: Manage build dependencies | Netlify Docs

Hi, thx for the answer.

i already uppate node. when i use “node -v” command in terminal, the answer given to me is " v18.13.0" .
i may haved miss something.
when i build on netlify, it say iv got 12.18.0

Ty for your answer,
sry i didnt see the doc @hrishikesh linked me

i read the doc, but clearly am not a pro. i understood that i have to set an environement variable NODE_VERSION but i dont know how.
When i go on netlify site in Environment variables set, it ask me a key and value but i dont know what i have to set.
i tryed with .env file but i dont know what i have to write in the file.

i dont know the simplest way to implemant environment variable.
i dont even know a way to do it.
Sorry, i guess its dumb ( and I probably am too

@d1991 You’re not dumb, everything is hard until it’s easy.

Learning to search and read the Documentation will get you a long way…

There’s a section within your Build settings in the Netlify UI which lets you set Environment Variables.
