首先需要安装这两个包:

First you need to install these two packages:

npm install gulp-babel babel-plugin-transform-react-jsx

然后你可以这样转换:

var gulp = require('gulp');
var babel = require('gulp-babel');

gulp.task("babel", function(){
    return gulp.src("src/jsx/*.jsx").
        pipe(babel({
            plugins: ['transform-react-jsx']
        })).
        pipe(gulp.dest("src/js/"));
});
