Babel 在 Node.js 中不起作用 SyntaxError: Unexpected identifier

Question

I'm hosting a nodejs project on server, that uses ES6 syntax, and I used babel-cli to compile it. I don't have any problem in my localhost, but when i host it I get this error:

import express from 'express';^^^^^^^SyntaxError: Unexpected identifier

my node version is v10.16.0

package.json :

 {
  "name": "example",
"version": "1.0.0",
 "description": "",
 "main": "index.js",
 "scripts": {
  "test": "echo \"Error: no test specified\" && exit 1",
   "start": "nodemon ./index.js --exec babel-node -e js"
},
"author": "",
"license": "ISC",
"dependencies": {
 "bcrypt": "^3.0.2",
 "express": "^4.16.3",
 "jsonwebtoken": "^8.4.0",
"mongodb": "^3.1.6",
"mongoose": "^5.3.1",
"nodemailer": "^6.2.1",
"nodemon": "^1.18.4",
"randomstring": "^1.1.5",
"shortid": "^2.2.14"
 },
"devDependencies": {
"babel-cli": "^6.26.0",
"babel-preset-env": "^1.7.0",
"babel-preset-stage-0": "^6.24.1"
 }
}

and for .babelrc :

      {
    "presets": [
    "env",
    "stage-0"
]

}

import express from 'express';
   ^^^^^^^
