METRO BUNDLER ERROR: Metro Has Encountered an error: Cannot read properties of undefined(reading 'transformfile')

I'm not sure why it is showing up like this, The problem occured on Bundler.js, and the error pointed to this line.

TransformFile(filePath, transformOptions) {
    var _this3 = this;

    return _asyncToGenerator(function*() {
      // We need to be sure that the DependencyGraph has been initialized.
      // TODO: Remove this ugly hack!
      yield _this3._depGraphPromise;
      return _this3._transformer.transformFile(filePath, transformOptions);
    })();

It might be important to add that I installed node via nvm.

Thank You!
