如何在命令行中直接运行node/babel脚本? [英] how to run node / babel script directly in command line?

问题描述

我的package.json看起来像:

My package.json looks like:

{
  "name": "99-nodetest",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "babel-node --presets env app.js"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "babel-cli": "^6.26.0",
    "babel-preset-env": "latest"
  }
}

我要运行的js脚本是app.js.我无法使用 node app.js 直接运行它，因为app.js包含新的语言语法.

The js script i want to run is app.js. I cannot run it directly using node app.js because app.js contains new language syntax.

因此，我必须按照上面定义的启动脚本，使用 npm start 通过babel运行它.这里没有问题.

Thus i have to run it through babel, using npm start, as per the start script defined above. No issues here.

我的问题是如何直接在命令行中运行cmd，可以做到吗? 类似于:

My question is how to run the cmd directly in the command line, can it be done? something similar to:

npm运行babel-node --presets env app.js

npm run babel-node --presets env app.js

推荐答案

node ./node_modules/babel-cli/bin/babel-node.js --presets env app.js
