Hello I've recently upgraded to next 14 and started a new project and anytime i try npm run dev i get an issue that tells me that I'm running an older and unsupported version of node which I don't even have installed. (I have node v20). Can someone help me? I've tried using nvm and uninstalling node completley.

if you run npx next info what does it show (esp node version)
also im guessing node -v shows the v20?
Least TernOP
C:\Windows\system32>node --version
v20.11.1
@riský if you run `npx next info` what does it show (esp node version)
Least TernOP
this is what i get
but when i run the npm run dev
you are using node.js 17.3.0. for next.js, node.js version >= v18.17.0 is required.
@Least Tern this is what i get

Least TernOP

nice
can you run where node and see if the top path is the correct one with your install
Least TernOP
yes
and is there any others there that may be the older version
Least TernOP
C:\Program Files\nodejs\node.exe
i really wonder where next is getting its node from
Least TernOP
me too
i deleted every folder of node
and even in registry
still can't run the new project?
Least TernOP
I can create new project
but it won't start
i just created another one
just in case the other one is corrupted
hmm, same result/error?
last thing, is node --print "process.versions.node" correct (this is what the next uses to get it)... but there has to be someting more broken
for example deleting node_modules and npm cache like npm config get cache.... but i cant see how that would fix it
Least TernOP
it randomly started workin 💀
