Cannot find module 'webpack

'This error message usually indicates that the Webpack module is not installed or cannot be found in the current working directory.

To resolve this issue, you can try the following steps:

1. Install Webpack globally by running the following command:

npm install -g webpack

2. If you have already installed Webpack locally in your project, make sure that you have added it to your project's dependencies in the `package.json` file and that you have installed it by running the following command:

npm install webpack --save-dev

3. Check that the Webpack module is installed in the correct directory. If you have installed it globally, it should be located in the global `node_modules` directory. If you have installed it locally, it should be located in the `node_modules` directory of your project.

4. Ensure that you are running Webpack in the correct directory. Make sure that you have navigated to the correct folder in the command line before running the Webpack command.

5. If none of the above steps work, try deleting the `node_modules` directory and then reinstalling all dependencies by running the following command:

rm -rf node_modules && npm install
