gatsby-source-wordpress不起作用

我是React和Gatsbyjs的新手 . 我能够使用盖茨比网站的4个教程创建一个网站 . 当我的页面是js文件或Markdown时，它正在工作 .

我尝试安装gatsby-source-wordpress插件，但是当我输入gatsby develop时Gatsby无法导入数据 .

我看到这个警告：警告gatsby-source-wordpress插件没有生成Gatsby节点 . 你需要它吗？

版本：

盖茨比=> 1.1.39

Node => v8.9.4

Mac High Sierra 10.13.3

我在dreamhost vps主机上使用全新安装的WordPress 4.9.4 . 该网站正在使用来自Let's encript的https！

这是我在终端中看到的消息 .

 You can now view gatsby-starter-hello-world in the browser.

  http://localhost:8000/

  View GraphiQL, an in-browser IDE, to explore your site's data and schema

  http://localhost:8000/___graphql

 Note that the development build is not optimized.
 To create a production build, use gatsby build
