NextJS - ReferenceError: Request is not defined | Reading old version of Node

Question

When I run npm run dev in my nextjs project I get the following error:

.../node_modules/next/dist/server/web/spec-extension/request.js:28
class NextRequest extends Request {
                          ^

Node.js v17.4.0

When I run node -v I get:

v20.9.0

I have already uninstalled node from my machine and reinstalled it using nvm.

From what I understood nextjs and the packages I have installed are complaining because I am not using the required node version. However since in my terminal when I run node -v I get that I am using v20.9 I'm not sure why else Nextjs isn't detecting the correct node version

Anyone know how I can solve this?

Answer 1

Open terminal inside your project and then run below mentioned command

npm i node@lts

This does not work on a pc using v 16.15.1 I observed that it works for all versions of node greater that 18. – Nork

I says No matching version found for – Analects

Answer 2

I got this issue when using a node version below 18 which is actually required by nextJs 13. If you are not using node version manager, I suggest you install it you can find details about how to install it here

Then run nvm install 18 this will install and set your current version to 18. Then just run yarn dev or npm run dev to start your development server.

Answer 7

It happened to me. I was working on 2 projects one was in React and the other one was in nextJs. For react project node 16 was used and 20 for nextjs project.

I faced this error because when I was running the next app, I was using node 16. So I just changed the node version to 20 and restarted the app. It started working fine.

So finally that was the issue of the node version. Just type

nvm use 20

if it's not installed?

nvm install 20

and then shift to node 20

Now restart your project and it will work.
