metro.config.js:

module.exports = {
    transformer: {
        babelTransformerPath: require.resolve("./transformer"),
        getTransformOptions: async () => ({
            transform: {

Error I am getting:

I find the solution when using with react-native 0.61 This is my metro.config.js My problem disappear when I change babelTransformerPath: require.resolve(“./transformer”) to getTransformModulePath: () => { return require.resolve(‘./transformer’); },

module.exports = {
  transformer: {
    getTransformOptions: async () => ({
      transform: {
        experimentalImportSupport: false,
        inlineRequires: false,
      },
    }),
    getTransformModulePath: () => {
      return require.resolve('./transformer');
    },
  },
};
