Gulp gulp markdown-to-json类型错误

Question

给定标记和markdown-it的自述文件中的示例：

来自markdown-it's README.md

var md = require('markdown-it')();
var result = md.render('# markdown-it rulezz!');

来自marked's README.md

var marked = require('marked');
console.log(marked('I am using __markdown__.'));

我尝试创建Gulp任务来将我的.md文件转换为.json。我首选的markdown解析器是markdown-it，但我在以下配置中遇到了错误：

// Gulpfile.js
const gulp = require('gulp');
const md2json = require('gulp-markdown-to-json');
const md = require('marked');
const mdb = require('markdown-it')();

console.log(md('*markdown*')); // => Works
console.log(mdb.render('*markdown*')); // => Works

gulp.task('md', () => {
  return gulp.src('src/**/*.md')
    .pipe(md2json(md))
    .pipe(gulp.dest('dst'))
})
// => Success

gulp.task('it', () => {
  return gulp.src('src/**/*.md')
    .pipe(md2json(mdb.render))
    .pipe(gulp.dest('dst'))
})
// => Error
// UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): TypeError in plugin 'gulp-markdown-to-json'
// Message:
//     Cannot read property 'renderer' of undefined

我做错了什么吗？

I think you've lost this context here:

.pipe(md2json(mdb.render))

Try

.pipe(md2json(mdb.render.bind(mdb))
