Error: Cannot find module '@babel/core'

This error occurs when the required module '@babel/core' is not installed or is not found in the node_modules directory of your project.

To fix this error, you can follow the below steps:

1. Install '@babel/core' module using the npm command:

npm install --save-dev @babel/core

2. If the module is already installed, try deleting the 'node_modules' directory and reinstalling all the dependencies using the following command:

rm -rf node_modules && npm install

3. Check whether the module is listed in the 'dependencies' or 'devDependencies' section of your 'package.json' file. If not, add it to the respective section and run 'npm install' command again.

Once you have installed the module successfully, the error should be resolved.
