In my app.js,

const app = require("express")();

const port = 3000;

app.get("/", (req, res) => {
  res.send("hello world");
});

app.listen(port, () => {
  console.log("server running!");
});

This error generated after I save / update the app.js file,

Today I updated my npm to 7.19.1, after that I am getting this error. Otherwise, it has to do something with nodemon.

npm nodemon express node.js

Maybe the new version of nodemon is causing this. So, I've degraded the version to 2.0.7 which is working fine for me!

npm uninstall nodemon
npm install nodemon@2.0.7 --save-dev

You check nodemon -v, if nodemon is not recognized then npm install -g nodemon -> nodemon app.js

try installing nodemon verson 2.0.7 globally

first install the current version npm uninstall -g nodemon then write the command npm i -g nodemon@2.0.7

atleast it worked for me :)

The system32 folder's path was not found. As soon as I added it to the system path, it worked as it should.The problem was not with nodemon, it was my system that was missing the system32 folder's path in environment variables. System32 folder contains important operating system files that Windows needs in order to function properly. For this case the command was not automatically refreshing (nodemon).

Updating your nodemon to the latest version will resolve this issue.

npm install nodemon

Running above command will update nodemon to the latest version.
