error: bundling failed: Error: Unable to resolve module `react-native-get-real-path` from `App.js`: react-native-get-real-path could not be found within the project.

If you are sure the module exists, try these steps:
 1. Clear watchman watches: watchman watch-del-all
 2. Delete node_modules: rm -rf node_modules and run yarn install
 3. Reset Metro's cache: yarn start --reset-cache
 4. Remove the cache: rm -rf /tmp/metro-*

I'm using Ubuntu 19.10. Moreover, I have installed the package properly. here is the App.js code;

import RNGRP from 'react-native-get-real-path';

async MultipleFilePicker() {
    try {
      const res = await DocumentPicker.pickMultiple({
        type: [DocumentPicker.types.allFiles],

      });

      for (const results of res) {
        //Printing the log realted to the file
        console.log('res : ' + JSON.stringify(results));
        console.log('URI : ' + results.uri);
        console.log('Type : ' + results.type);
        console.log('File Name : ' + results.name);
        console.log('File Size : ' + results.size);

        //get the files URI
        let url = results.uri;
        const split = url.split('/');
        const name = split.pop();
        const inbox = split.pop();

        // Create an accesible file path
        const realPath = `${RNFS.TemporaryDirectoryPath}${inbox}/${name}`;
        // Print the file path
        console.log('real path' + realPath);

        RNGRP.getRealPathFromURI(realPath).then(filePath =>
          console.log("RNGRP : "+ filePath)
        )

        // Recheck if the selected file exists
        RNFS.exists(realPath).then((success) => {
          console.log('FILE exists!');
          console.log('Success result' + success);
        }).catch((err) => {
          console.log('Returned an error!');
          console.log(err.message);
        })
      }

      this.setState({ multipleFile: res });


    } catch (err) {
      if (DocumentPicker.isCancel(err)) {
        Alert.alert('Canceled');
      } else {
        Alert.alert('Unknown Error: ' + JSON.stringify(err));
        throw err;
      }
    }
  }
