Javascript 使用markdown it解析markdown引用

我正在使用解析一个降价文件。我的资料来源如下：

![Build Status][1]

我一直在使用它来获取解析数据，但是现在它让我失望了

有一个降价的现场演示。我把我的来源放进去了，它工作得很好。在该页面上有一个

debug

选项卡，我期望的确切输出就在那里

我如何解决这个bug并使用它获得预期的输出

我是否可以调用另一种方法来提供正确的输出

这似乎需要一个

env

，它是

我使用的是4.4.0版（未在NPM上发布，在github上的主标记）

以下是一些源代码：

var fs = require('fs')
var markdown = fs.readFileSync('./readme.md', 'utf8')
var MarkdownIt = require('markdown-it')
var md = new MarkdownIt()
var parsedMd = md.parse(markdown)

---

我相信这解决了问题：

var parsedMd = md.parse(markdown, {})
