I am facing an error when trying to run my Parcel project. The error in the browser console is:

Uncaught Error: Cannot find module '@parcel/transformer-react-refresh-wrap/lib/helpers/helpers.js' at newRequire (react-weather-project.f03ac8bf.js:70:19) at newRequire (react-weather-project.f03ac8bf.js:54:18) at localRequire (react-weather-project.f03ac8bf.js:93:35) at newRequire (react-weather-project.f03ac8bf.js:80:24) at react-weather-project.f03ac8bf.js:140:5 at react-weather-project.f03ac8bf.js:159:3

Steps to reproduce:

1. Installed dependencies using npm install
2. Started the project using npm start
3. Error appeared in the console

What I've tried:

• Cleared Parcel cache & reinstalled dependencies

  rm -rf .parcel-cache node_modules package-lock.json
  npm install
  

• Reinstalled Parcel

  npm uninstall parcel && npm install --save-dev parcel
  

• Installed missing module

  npm install --save-dev @parcel/transformer-react-refresh-wrap
  

But the error still occurs.

My environment:

• OS: Ubuntu 24.04.2 LTS
• Parcel Version: 2.14.1
• Node.js Version: 22.12.0
• npm Version: 11.2.0

package.json:

Yo! to solve this error i removed "main" in package.json and if you encounter "failed to resolve react-router/dom" something like this then add this code below code in your package.json file

"@parcel/resolver-default": {
      "packageExports": true
}
