node throw error when use async/await syntax.but it works well with import/export syntax

nodemon throw the error when use async/await syntax:



**/node_modules/@babel/runtime/helpers/esm/asyncToGenerator.js:17
export default function _asyncToGenerator(fn) {
^^^^^^
SyntaxError: Unexpected token export


but it works well with import/export syntax.



package.json



{
"scripts": {
"dev": "nodemon --exec babel-node server/index.js",
}
"dependencies": {
"@babel/polyfill": "^7.2.5",
},
"devDependencies": {
"@babel/cli": "^7.2.3",
"@babel/core": "^7.2.2",
"@babel/node": "^7.2.2",
"@babel/preset-env": "^7.2.3",
}
}


.babelrc



{
"presets": [
"@babel/preset-env"
]
}


asyncToGenerator.js



function asyncGeneratorStep(...) { ... }
export default function _asyncToGenerator(fn) {
return function () {
var self = this,
args = arguments;
return new Promise(function (resolve, reject) {
var gen = fn.apply(self, args);

function _next(value) {
asyncGeneratorStep(gen, resolve, reject, _next, _throw, "next", value);
}

function _throw(err) {
asyncGeneratorStep(gen, resolve, reject, _next, _throw, "throw", err);
}

_next(undefined);
});
};
}


But I think it probably goes wrong because of my babel setting.



BTW, when I use typeof, it throws the same error



**/node_modules/@babel/runtime/helpers/esm/typeof.js:3
export default function _typeof(obj) {
^^^^^^
SyntaxError: Unexpected token export

  • Can you please post full script of asyncToGenerator.js? async/await is not related to import/export
