Gatsby: gatsby源-graphql:无法读取未定义的属性“createPageDependency”

Question

我正在为fireblog ( https://fireblogcms.com/ )构建一个Gatsby主题，它有一个GraphQL API。因此，我尝试了gatsby-source-graphql插件，这似乎是可行的方法：

当按照本页的说明：https://www.gatsbyjs.org/packages/gatsby-source-graphql/然后访问http://localhost:8000/___graphql时，我在对新类型运行GraphQL查询时遇到了这个问题Cannot read property 'createPageDependency' of undefined。

复制：

将此配置

• yarn add gatsby-source-graphql
• add到gatsby-config.js

  plugins: [
    // Simple config, passing URL
    {
      resolve: "gatsby-source-graphql",
      options: {
        // This type will contain remote schema Query type
        typeName: "fireblog",
        // This is field under which it's accessible
        fieldName: "fireblog",
        // Url to query from
        url: "https://api.fireblogcms.com/graphql/blog/5de7a2934360f60004130881"
      }
    },
  //...
  ], 

转到http://localhost:8000/___graphql

并运行查询：

{
  fireblog {
    posts(last: 20) {
      edges {
        node {
          title
        }
      }
    }
  }
}

预期结果

我期望查询在没有错误的情况下运行，或者提供一条错误消息来解释下一步我应该做什么来使这个查询工作。

实际效果

发生了什么：

{
  "errors": [
    {
      "message": "Cannot read property 'createPageDependency' of undefined",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "path": [
        "fireblog"
      ]
    }
  ],
  "data": null
}

Answer 1

问题似乎是我的节点版本，我在节点12.4.0上的最后一次测试没有问题。如果我记得清楚的话，我以前在节点10.13.0
