Question

我不完全确定如何使用babel和gulp并将一些反应jsx文件编译为JavaScript。

我已经安装了nodejs，babel-cli，gulp-babel，babel-preset-react和babel-preset-es2015

节点模块出现在我的工作目录中，一切似乎都在那里。

我的package.json文件如下所示：

{
  "name": "example1",
  "version": "1.0.0",
  "babel":{
    "presets": ["react", "es2015"]
  },
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "babel-cli": "^6.7.5",
    "babel-preset-es2015": "^6.6.0",
    "babel-preset-react": "^6.5.0",
    "gulp-babel": "^6.1.2"
  }
}

我的gulpfile.js看起来像这样：

var gulp = require('gulp');
var react = require('gulp-react');
var concat = require('gulp-concat');
var babel = require("gulp-babel");

gulp.task('default', function(){
    return gulp.src('src/**').pipe(react()).pipe(concat('application.js')).pipe(gulp.dest(' ./'))
});

我相信这是将我的文件编译为JavaScript所需的所有设置。但是，当我尝试npm run gulp时，从命令提示符处获得以下输出，我不确定如何解释：

npm ERR! argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "run" "gulp"

如何使我的.jsx反应文件编译为.js？

编辑：

在"gulp":"gulp"中的脚本下添加package.json，然后运行npm run gulp，即可让我：

    throw err;
    ^

如果您想使用npm run gulp从项目本地安装中运行gulp，则必须向gulp添加package.json脚本：

"scripts": {
  "test": "echo \"Error: no test specified\" && exit 1"
  "gulp": "gulp"
},
